Unmatched performance and reliabilityBypass isolation ATS Eaton’s bypass isolation automatic transfer switch (ATS) is designed to provide unmatched performance, reliability and versatility for critical standby power applications. Supervisory intelligence is provided by an ATC-900 or ATC-300+ controller, delivering operational simplicity and field adaptability coupled with diagnostic and troubleshooting capabilities. The bypass isolation ATS design is ideal for those applications where the ability to perform maintenance is required without interrupting power to life safety and other critical loads.Product configuration• Automatic operation—ATS and bypass switch• Open and closed transition• 100–1200 A rating• Two-, three- or four-pole• NEMA T 1, 3R• Up to 600 Vac, three- orfour-wire, 60 Hz or 50/60 Hz• Drawout ATS and fixedbypass switch, facilitatingconcurrent maintenance• Service entranceFeatures and benefitsProven performanceand reliability• Automatic and non-automaticoperation modes are availableto provide multiple methods oftransferring the load betweenpower sources• Manual operation allowsunloaded transfer betweenpower sources for allproduct configurations• UL T 1008 Listed short-circuitand short-time (select catalognumbers only) withstandclosing current ratingsmaximize system reliabilitySimplified installationand integration• Factory-configured powersource and load terminalsfor top/bottom cable ingress• Removable enclosure panelsprovide front and rear accessto cable terminal connections• Seismic certified to OSHPD,CBC, IBC and UBCEnhanced safety• Two-door, compartmentalizedconstruction provides steelbarriers, protecting workers• Integral safety interlocksautomatically open the maincontacts prior to the ATSbeing isolated for test orremoved for serviceImproved serviceability• Two-door design eliminatesthe need to scheduleshutdowns for routine test,inspection or maintenanceof the ATS• Drawout design allows theATS to be disconnectedfrom the electrical bus andisolated in cell for regulartesting as prescribed bycode (NFPA T 70, 99, 110)• Testing of the isolated ATScan be performed whilethe bypass switch is in theautomatic or non-automaticmode of operationDesign featuresDual automatic technology Eaton’s bypass isolationtransfer switch design includes an automatic bypass switch and an ATS housed within a single assembly.Regardless of which power switch is actively distributing power, redundant automatic operation provides for a rapid load transfer and restoration of power to life safety and critical loads, eliminating the need for active supervision by qualified personnel.Segmented construction The ATS and automatic bypass switch are housed in separate compartments, with robust steel walls, that isolate the power switches from each other to facilitate ease of maintenance and worker safety. Eachcompartment includes a door with padlockable handle. This design prevents the possibility of inadvertent contact andunnecessary exposure to power cable terminations and energized electrical control components.Drawout ATS and fixed-mounted bypassService personnel can rack-out and isolate the ATS (with compartment door closed) from the electrical bus for routine test or exercise. A Kirk T -key interlock prevents access to the racking mechanism until the load connection has been transitioned to the automatic bypass switch.Opening the compartment door allows the ATS to be completely drawn out of the cell for inspection or maintenance.Safety interlocks prevent rack-out or rack-in of the ATS from the electrical bus with the main contacts closed. The automatic bypass switch is fixed mounted to the electrical bus and stands ready to initiate an automatic load transfer when the ATS is undergoing maintenance.Multi-tap control power transformerSystem voltage can be fieldconfigured via a multi-tap control power transformer (CPT) with quick-disconnect plugs.T ransition to bypass mode When maintenance or testing of the ATS needs to be performed, qualified personnel can easily and quickly transition the load connection between the ATS and automatic bypass switch using door-mounted operator controls fitted with indication lights. The transition occurs in a make-before-break fashion, ensuring continuous power flow to loads.Multiple operation modes Operation is possible in the following modes:• Automatic • Non-automatic •Manual AIn automatic mode, the transfer switch is self-acting, and atransfer is automatically initiated by the intelligent logic controller.In non-automatic mode(optional), a transfer is initiated by the operator using a door-mounted selector switch.In manual mode, a transfer is initiated by the operator using controls mounted directly on the automatic bypass switch or ATS.Alternatively, a transfer can be initiated remotely via an HMi remote annunciator controller.A Manual operation (unloaded) is provided forall product configurations.for top and bottom cable terminationFixed-mounted automatic Drawout ATS can be isolated for test within compartment orand automatic bypassswitch compartments600–1200 A rating (480 V), NEMA 1 enclosure100–400 A rating (480 V), NEMA 1 enclosureFixed-mounted automatic Drawout ATS can within compartmentor completely removedRemoveable optionpanels allow front access for top and bottom cableterminationDrawout ATS removed for bench level inspection/Automatic bypass switch stands ready to transfer load2EATON Bypass isolation automatic transfer switchesStandard enclosure dimensions and weightsDimensions and weights shown are approximate and subject to change.

Application1.Remote Sense Connection ifnot usedNotes ：(1)If the sense function is not used for remote regulation the user must connect the +Sense to +Vo and -Sense to 0V at the DC-DC converter pins and will compensate for voltage drop across pins only.(2)The connections between Sense lines and their respective power lines must be kept as short as possible,otherwise they may be picking up noise,interference and/or causing unstable operation of the power module.2.Remote Sense Connection Notes:(1)Using remote sense with long wires may cause unstable output,please contact technical support if long wires must be used.(2)PCB-tracks or cables/wires for Remote Sense must be kept as short as possible.Twisted pair or shielded wairs are suggested for remote compensation and must be kept as short as possible.(3)We recommend using adequate cross section for PCB-track layout and/or cables to connect the power supply module to the load in order to keep the voltage drop below 0.3V and to make sure the power supply's output voltage remains within the specified range.(4)Note that large wire impedance may cause oscillation of the output voltage and/or increased ripple.Consult technical support or factory for further advice of sense operation.1.Ripple &NoiseAll the DC-DC converters of this series are tested before delivery using the recommended circuit shown in

that at least a 100μF electrolytic capacitors is connected at the input in order to ensure adequate voltage surge suppression and protection.Input and/or output ripple can be further reduced by appropriately increasing the input &output capacitor values Cin and Cout and/or by selecting capacitors with a low ESR (equivalent series resistance).Also make sure that the capacitance is not
