Notes:

1. Output regulation includes line & load.

2. Ripple & noise is measured from 10 Hz to 20 MHz. Measurement connection to the

unit is made with a 0.1 µF ceramic capacitor & a 22 µF electrolytic capacitor con-

nected in parallel.

3. Transient recovery is measured to within a 1% error band for a load step change of

50% to 100%.

4. Isolation specifications are production HI-Pot tested for 3 seconds.

5. The full output range (see table above) is covered in the safety

agency certification. Standard models are factory set to the

“Preset” voltage.This may be set to other levels within the range

without affecting the agency certification. For more information,

contact the factory.

6. Units will provide peak power of 600W for 500 µS. For units

capable of longer durations, contact the factory.

7. A 1% minimum load is required to maintain regulation and ripple

specifications.
