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. Stan-

dard 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 load of 1% is required to maintain load regulation and ripple specifications.

7. Output current is given for the factory preset voltage.With the exception of the “03”

(297W) and “05” (450W) output models, the maximum continuous output power level is

600W with 30 CFM. For more information, contact the factory.

8. Units will provide peak power of 900W for 500 µS. For units capable of longer durations,

contact the factory.
