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 & 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. 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.

7. Output current is given for the factory preset voltage.With the exception of the “05”

output model, the maximum continuous output power level is 320W (with 22 CFM),

180W (U-Chassis convection cooled) or 170W (“C” units convection cooled. For more

information, contact the factory.

8. Units will provide peak power of 700W for 500 μS. For units capable of longer durations,

contact the factory.

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