Model Selection Guide

Notes:

1. Output regulation includes line & load.

2. Ripple & noise is measured from 10 Hz to 20 MHz. Connec-

tion to the unit is made with a 0.1 µF ceramic capacitor and

a 22 µF electrolytic capacitor connected in parallel.

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

ripple specifications.

4. Transient recovery is measured to within a 1% error band

for a load step 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

7. Output power is given for the factory preset voltage. The maximum

continuous output power level is 220W without providing 26.85 CFM

airflow.All models provide a peak power level of 700W for a maximum

duration of 500 µS. For more information, contact the factory.

8. Each unit includes an input fuse (T8A/250V). 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.
