Notes:
1. Output regulation includes line & load.
2. Ripple & noise is measured from 10 kHz 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 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 135W without providing 16 CFM airflow. All models provide a peak power
level of 600W for a maximum duration of 500
µS.
For more information, contact the factory.
8. Each unit includes an input fuse (250V/8A). 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.
