Notes:

1. Output regulation includes line & load.

2. Ripple & noise is measured from 10 Hz to 20 MHz. Connection to the unit is made with a 0.1 µF ceramic capacitor &

a 22 µF electrolytic capacitor connected in parallel.

3. A 1% minimum load is required to maintain regulation & ripple specifications.

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) is covered in the safety agency certification. Standard models are factory set to the

Preset voltage, but may be set to other levels within the range without affecting the agency certification. For more

information, contact the factory.

7. Output power is given for the factory preset voltage.The maximum continuous output power level is 800W.All models

provide a peak power level of 900W for a maximum duration of 500 µS. For more information, contact the factory.

8. Each unit includes an input fuse (250V/12A).Since this fuse is not field replaceable,it is recommended that an external

fuse of the same size be used on the input of the power supply for protection.
