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 400W with 23 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 two (250V/8A) fuses. Since these fuses are 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.
