A. INPUT CHARACTERIZATION

1.1 INPUT CURRENT/POWER/EFFICIENCY/POWER FACTOR

Test conditions:

The unit is set at maximum load and the input voltage is varied from the minimum to the

maximum value. Efficiency is computed and Power Factor is either computed or measured after

10 minutes warm up at least.

Test equipment:

Chroma Model 8000 Power Supply Auto Test System

Chroma Model # 6590 9KVA Low Impedance AC Source

Chroma Model # 630X0 DC Load

Chroma Model # 6630 Power Analyzer

Pass/Fail criteria:

The unit test shall meet the specification requirements.

Test result: PASS
