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 600W with 25 CFM airflow.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/10A). 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.

9. The Fan Drive output (at connector CN4) provides 12V/300 mA to drive an external fan.

Signal

Goes TTL high 100 to 500 mS after

regulation. Goes low at least 1 mS

before the loss of regulation. Will sink
