Notes:

1. Models are available with leakage current specified as low as 500 µA (at 240 VAC) /

300 µA (at 120 VAC). Contact the factory for details.

2. Output regulation includes line & load.

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

the unit is made with a 0.1 µF ceramic capacitor and a 22 µF electrolytic capacitor

connected in parallel.

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

50% to 100%.

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

6. 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.

7. Output current is given for the factory preset voltage.With the excep-

tion of the “05” & “09” output models, the maximum continuous

output power level is 250W (with 16 CFM), convection cooled) or

135W convection cooled. For more information, contact the factory.

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

capable of longer durations, contact the factory.

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

specifications.
