Notes:

1. Models are available with leakage current specified as low as 750 µA.

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 & 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. 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. Contact the factory for

details.

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

7. Output current is given for the factory preset voltage. For more information, contact the

factory.

8. Units will provide peak power of 600W for 500 µS. For units capable of longer dura-

tions, contact the factory.
