The waveformsProgrammable DC Electronic LoadC h ro m a 6310APro gra m m a b l e E l e c t ro n i c Lo a d i nte grate s microprocessor capabilities into each load module and mainframe to provide simple and accurate parallel operation to optimize the speed and control among multiple load modules. All load modules may be configured to work synchronously, to test multiple outputs simultaneously, thus simulating real life applications.The 6310A load modules operate in constant current, constant voltage,constant power or constant resistance to satisfy a wide range of test requirements. For example, the test of a battery charger can be simulated easily by setting the load to operate in constant voltage.APPLICATION OF SPECIFIC LOAD SIMULATIONThe 6310A series load modules will be compatible with the 6310 series mainframes (6312/6314). In addition, the remote control commands will be compatible between the 6310 and the 6310A series without needing to re-writing any remote control programs.COMPATIBILITY WITH 6310 SERIESMODULE LOAD DESIGN8-channel 100W/channel load with standard front-panel inputs. This makes it ideal for testing multiple output switching power supplies and multiple DC-DC converters. There are also higher wattage modules that may be mixed and matched for an even more versatile system. Additionally, the GO/NG output port is useful for UUT's pass/fail testing on an automated production line. All modules on the 6314A/6312A mainframe share a common GPIB address to synchronize and speed up the control of the load modules and the read-back of data.The Chroma 6314A 1400W and 6312A 700W electronic load mainframes accept the user-installable 6310A series load modules for easy system configuration and will mount in a 19" instrument rack. The6314A holds up to four 63102A load modules, which will result in anEach load module is designed with state-of-the-art technology and connects all the power MOSFET devices in parallel to insure high accuracy load control with a minimum drift of less than 0.1%+0.1%F.S. of the current setting. Chroma's use of FET technology provides minimum input resistance and enables the load to sink high current even at very low voltages. For example, the model 63123A is capableof sinking 70A at 0.6V, and well-suited for testing the new 3.3V low voltage power supplies. Low voltage operation, down to zero volts, is possible at reduced current levels.The 6310A load module uses a photo coupler for isolation between the output and control sections, thus each load is isolated and floating. The user can use multiple load modules independently to test multi-output power supplies, or parallel them for high power testing applications.DYNAMIC LOADING AND CONTROLModern electronic devices operate at very high speeds and require fast dynamic operation of their power providing components. To satisfy these testing applications, the 6310A loads offer high speed, programmable dynamic load simulation and control capability. The figure aside shows the programmable parameters of the 6310A modules:The programmable slew rate makes the simulation of transient load change demanded by real life applications possible. The 6310A internal waveform generator is capable of producing a maximum slew rate at 10A/µs, and dynamic cycling up to 20kHz. It's dedicated remote load sense and control circuit guarantee minimum waveform distortion during continuous load changes.MULTI CHANNEL CONTROLThe 6310A comes with RS-232C as standard for remote control and automated testing applications. The USB and GPIB interfaces are available as options. In addition, the 6310A provides an efficient solution for testing single output AC to DC or DC to DC converters by controlling multiple loads. The 6310A provides the capability to test upto 8 UUTs at a time.UUT : AdaptorThe 6310A series of loads include a unique timing & measurement function, which allows precise time measurements in the range of 1ms to 86,400s. This feature allows the user to set the final voltage & timeout values for battery discharge testing, super capacitor discharge, and other similar applications.For example, the figure on the right shows the 6310A internal timer starting at Load ON, and ending when the battery voltage reaches the final voltage.The digital I/O interface makes the 6310A DC Load the ideal choice for automated testing requirements. Through the digital I/O, the 6310A can accept digital signals to trigger its functions (Load On/Off, OCP test, etc.) as well as current output status signals.Each 6310A load module has an integrated 16-bit precision A/D converter for voltage measurement with an accuracy of 0.025%+0.015%* of full scale. The built-in resistive load current sensing circuit is capable of measuring current with an accuracy of 0.04%+0.04%* of full scale. Apart from voltage and current measurement, 6310A also provides power measurement function and there is no need for users to spend time for power calculation. Also, short circuit can be simulated. All measurements are done using remote sensing to eliminate any error due to voltage drops along the measurement path. The user can also select from a complete set of voltage and current measurements.Note * : Only for Model 63123AModern switching power supplies are designed with over current protection (OCP) circuitry; therefore, it is important to test the OCP circuitry to make sure it is functioning within its designed specifications. The 6310A series provides an easy and fast solution for this testing.By simply choosing the channel and setting the OCP parameters (start current, end current, step current and dwell time) from the front panel, the 6310A series provides a fast and easy OCP testing solution. The 6310A series will automatically detect the OCP point, making it an ideal solution for design verification as well as production line testing.Battery Discharge Testing6314A : 4 in 1 Mainframe A631001:Remote ControllerA631000 :GPIB Interface63106A / 63108A63102A / 63107A / 63110A63101A63105A63112A63103A / 63123A /63113A / 63115A6312A : 2 in 1 Mainframe A631003 :USB InterfaceAs a constant current source, the LED power driver has an output voltage range with a constant output current. LED power drivers are usually tested in one of the following ways :1. With LEDs2. Using resistors for loading3. Using Electronic Loads in Constant Resistance (CR) mode, or Constant Voltage (CV) mode However, all these testing methods, each of them has their own disadvantages.As shown on the V-I curve in Figure 1, the LED has a forward voltage VF and a operating resistance (Rd). When using a resistor as loading, the V-I curve of the resistor is not ableto simulate the V-I curve of the LED as shown in blue on Figure 1. This may cause the LED power driver to not start up due to the difference in V-I characteristic between the resistors and the LEDs. When using Electronic Loads, the CR and CV mode settings are set for when the LED is under stable operation and therefore, is unable to simulate turn on or PWM brightness control characteristics. This may cause the LED power driver to function improperly or trigger it's protection circuits. These testing requirements can be achieved when using a LEDs as a load; however, issues regarding the LED aging as well as different LED power drivers may require different types of LEDs or a number of LEDs. This makes it inconvenient for mass production testing.Chroma has created the industries first LED Load Simulator for simulating LED loading with our 63110A load model from our 6310A series Electronic Loads. By setting the LED power driver's output voltage, and current, the Electronic Load can simulate the LED's loading characteristics. The LED's forward voltage and operating resistance can also be set to further adjust the loading current and ripple current to better simulate LED characteristics. The 63110A design also has increased bandwidth to allow for PWM dimming testing.Figure 4 shows the dimming current waveform of the LED.Figure 5 shows the dimming current waveform when using 63110A as a load.Figure 1 - LED V-I characteristicsFigure 5 - 63110A dimming test Figure 6 - LED driver turn-on waveformFigure 4 - LED dimming test Figure 3 - Simulate different characteristic of LEDsFigure 2 - Simulate different number of LEDsRear Panel18 ON/OFF key : To enable or disable the load input 19 Up/Down key : To select the next or previous displayin edit mode20 Numeric key : For data setting21 ENTER key : To confirm editing data on the instrument 22 SHIFT key : As LOCAL key when in remote mode 23 Power switch24 SHIFT + 0 key : System function 25 SHIFT + . key : Lock function26 SHIFT + 3 key : Clear the currently edited data27 Digital I/O : Used for system input/output control signals 28 RS-232C connector 29 GO/NG output port 30 GPIB or USB slot31 AC input voltage switch 32 AC input fuse33 AC input connector1 LED indicator2 SHORT key : To apply a short circuit across the input3 STATIC/DYNA key : To select static or dynamic test mode4 L/R key : To select left or right channel of input load(63102A, 63107A) A/B key : To select static A or B load (other models)5 V terminal : To measure the UUT's output voltage using remote sense6 Rotary knob : To adjust load setting continuously7 Load terminal8 LCD display9 LED indicator : To display the channel at which load is set 10 CHAN key : To select input load channel11 MODE key : To select the operation mode of CC, CR, CV or CP 12 PROG key : For program data setting13 OCP/OPP key : Over current protection/Over power protection testing 14 RECALL key : To recall the front panel input status from memory 15 SAVE key : To save the front panel input status into memory 16 SPEC key : To set up High/Low limits for GO/NG test 17 CONF key :To set the configurationLoad ModuleMainframe ControllerNOTE*2 : S (siemens) is the SI unit of conductance, equal to one reciprocal ohm.

Chroma 6310系列电子负载操作指导书1 前言和目的本文阐明了Chroma 6310系列电子负载操作方法,便于实际的操作使用。

2 适用范围适用于Chroma 6310系列电子负载的使用操作。

3 操作规程仪器简介Chroma 6310系列电子负载6314插框可以放下四路电子负载,6312可以放下两路负载模块(63102、63103、63105、63107……),包括一个处理器,GPIB接口、RS-232接口、控制面板、以及显示器和PASS/FAIL信号。

具有SAVE/RECALL功能,可以储存100份文件,10个程序、一个缺省默认设计。

各路负载模块可以各自工作在CC、CR、CV三种模式,每个模块都具有一个或者两个通道(63103、63106为当通道模块,63102、63107为双通道模块),每个通道都有自己的编号(1~8),可以各自独立地turn on/ turn off,或short-circuited。

如果一个模块带载不够还可以将模块并联提高带载能力,当四路都加载时最大功率可达1200W。

其中控制面板有三个键都可以实现两个功能,将SHIFT 键与该键同时按下就可以实现另外一个功能。

插框面板按钮介绍1.电源开关2.LCD显示器3.通道显示4.功能键CHAN:选定通道进行设置MODE:用来选择带载模式(CC、CR、CV)PROG:用来编辑一组带载程序或者运行一组带载程序。

CLEAR:当数字输入错误后,按该键可以清除。

RECALL:可以用来调用先前存储的负载设置。

SAVE:当你设置好一种负载后可以使用该键保存到一个程序里面(1to10),下次使用可以通过RECALL(1to10)调用。

存储/调用(SAVE/RECALL)该系列负载可以对各路负载设定值按顺序储存在一个文件里,下次再要用到该系列负载时可以将此文件调用出来,如你要将已经设定好好的负载值储存到1号文件里,则只需按SAVE,然后按方向键,当显示器出现 SAVE PROGRAM 1:YES 2:NO时,按键“1”存储,当下次要再次调用该系列负载时,只需按RECALL,1,ENTER,则所有通道的设定值都回被条用出来,然后按LOAD即可加载。

SPEC:SPEC功能开关。

CONF:可以进行初始值CONF设置。

初始值设置Configuration按键CONF则弹出菜单CC Vrange Select 1:HIGH 2=LOW 设置模块带载端子电压范围选1则可以承受高电压,选2则电压范围小,超出范围模块报警。

ENTER,跳出设置带载点Von Point VOLTAGE:-V 在光标处输入加载点电压值,再ENTER,弹出Von Latch 1:ON 2:OFF 选1 一旦输出电压达到加载点Von Point开始加载,就算加载引起电压瞬间低于Von Point仍能继续加载,若选2则一旦电压被拉低小于加载点则马上卸载。

ENTER则出现CV. CURR-LIMIT CURRENT:-A 在光标处设置CV模式下的限流点。

ENTERSIGN OF VOLT 1:PLUS 2:MINUS 选1电压值为正选2为负,符合是“-”5.输入键上下方向键ON/OFF:负载带载卸载开关ENTER:回车键,设置参数后按该键确认写入SHIFT: 上档键,选择上档功能,或者在遥控状态下按该键可以转为本地面板操作。

0-9:数字键. :输入小数点负载模块面板按钮功能简介:1.7段LED显示2.模块通道LED显示(L/R):对于具有双负载通道的模块若标识R的LED亮,则右边标识R的通道使能,若标识L的LED亮,则左边标识L的通道使能,可以通过键R/L来切换。

对于单通道的模块63103、63106则没有该LED显示3.7段LED显示数值单位(电压/V,电流/A)4.带载模式与GO/NG显示:若检测不能满足SPEC设置,则GO/NG显示红灯,满足设置则显示绿灯。

5.键区显示灯6.键区:R/L、STATIC/DYNAMIC、SHORT、LOAD,当你按键后上方的LED灯就会亮红灯,分别实现该负载(R或者L)通道的动态负载、短路、带载功能。

对于模块加载卸载可以通过插框的主键盘的ON/OFF键来进行加载/卸载,或者通过单个模块LOAD键来控制。

有的模块如63102具有两路通道,左边的通道“L”和右边的通道“R”而这两个通道相互之间是隔离的,通过键“R/L”可以切换。

当两个通道同时选择时,两个LED等都亮,此时键STATIC/DYNAMIC、SHORT、LOAD操作不起作用。

对于单通道模块如右图则键区R/L为键A/B,A/B键上LED灯亮则灯亮选择的是A,灯灭选择的是B,选A则是LEVEL1,选B则是带载LEVEL2。

7.Vsense 端子:遥控操作的电压SENSE端。

8.旋钮:功能相当于数字键,顺时针方向旋转数值增加,逆时针方向数值减小。

9.负载带载正负端子。

“+”极必须必须接“UUT”的正,“-”接“UUT”的地。

具体应用1、负载带载模式设置各路负载模块可以各自工作在CC、CR、CV三种模式,更换负载模式只要通过“MODE”键选定所需的负载模式然后按“ENTER”键即可。

在更改模式的过程中,模块的输入自动关断以确保在切换负载时过冲最小CC.在CC恒流模式下会根据你编辑的数值提供负载电流,不受输入电压的影响,CC可由“MODE”键设置,当“MODE SELECT”字样在显示器上出现后,通过上下键,可以选定低负载范围“CCL”或者是高负载范围“CCH”,设定动态负载跳变时可以选择低动态负载范围“CCDL”或者是高动态负载范围“CCDH”然后按“ENTER”键即可。

CR在一定的CR下负载电流与输入电压成正比,在模块的输入端有一个双极性的RC滤波器,所以高频部分将会被滤掉,延迟时间大约为47uS,为防止由于输入电压的波动而带来负载电流的改变,电源阻抗必须尽量小,同时在大电流负载下必须使用遥控SENCE电缆去检测输入电压。

CR模式下也可以选择“LOW RANGE”CRL和“HIGH RANGE”CRH两个负载范围,可以通过方向键来选取,其负载值设定与CC类似,CR无法设置动态负载跳变。

CV在CV下负载将会控制电源输出电压到编辑值,也可以通过A/B来选定两个不同的电压值。

可以设计响应速率,对于CV模式有FAST和SLOW两个响应速度。

2、将所有负载通道都设置为CC模式下5A负载按键STATIC/DYNAMIC使LED灯灭,使负载工作在稳态负载下,在某些模块内(63103)设计了两个稳态负载值(A或B),可以通过建A/B来切换,灯亮选择的是A,灯灭选择的是B,选A则是LEVEL1,选B则是带载LEVEL2。

按CHAN键选择你要设置的通道;按“MODE”,当“MODE SELECT”字样在显示器上出现后,通过上下键,可以选定高负载范围“CCH”然后按“ENTER”键即可。

这样就确定了CC模式。

然后通过方向键选到下一步设置,在CCH1、CCH2分别设置为5A,按数字键2,ENTER。

CCH1:5ACCH2:5A设置加载速率,按键0 . 1CCH(加载速率):0.1A/uSCCH(卸载速率):0.1A/uS一个负载通道负载值设置完毕,按键CHAN再设置下个通道的负载值,所有通道都设置完毕后按键SAVE可以将设置的负载保存到一个文件里,下次需要时又可以调用出来。

然后按键“1”SAVE FILEFILE NO:1将该所有通道的负载设置保存到文件1里面下次需要该负载设置时,重新调用,按键RECALL,“1”,ENTER则又可以将设置好的负载调用出来。

3、CC模式下设置动态负载值按CHAN键选择你要设置的通道;按“MODE”,当“MODE SELECT”字样在显示器上出现后,通过上下键,可以选定高动态负载范围“CCDH”然后按“ENTER”键即可,而动态负载需编辑两个负载值(CCDH1,CCDH2),两个加载时间(CCDHT1,CCDHT2),以及负载跳变斜率,静态/动态功能可以通过键STATIC/DYNAMIC来切换。

当要设计电流值CCDH1为2A时,则可以按“2”键然后按“ENTER”,当要设计电流值CCDH2为4A时,则可以按“4”键然后按“ENTER”即可。

CCDH1:2ACCDH2:4A接着显示器会跳出变换时斜率大小值,若要修改为上升率为1A/uS以及下降速率为1A/uS,则对上升速率按“1”“ENTER”,对下降速率按“1”“ENTER”。

CCDH(加载速率):0.1A/uSCCDH(卸载速率):0.1A/uS对于动态负载跳变设计,动态还有一个各负载带载时间设定,如CCDHT1:2mS,CCDHT2:4mS,则分别按设定的值,然后再按ENTER即可。

CCDHT1:2mSCCDHT2:4mS然后按键CHAN则可切换负载模块,继续设置另一个通道模块的带载值。

所有通道都设置完毕后按键SAVE可以将设置的负载保存到一个文件里,下次需要时又可以调用出来。

然后按键“2”SAVE FILEFILE NO:2将该所有通道的负载设置保存到文件2里面下次需要该负载设置时,重新调用,按键RECALL,“2”,ENTER则又可以将设置好的动态负载调用出来使用。

按键STATIC/DYNAMIC,LED灯亮,LOAD ON开始输出设置好的动态负载,进行2A(2mS)~4A(4mS),1A/uS,的动态负载跳变。

CR、CV负载设置与CC类似,但是不能进行动态负载跳变。
