Some models may require a minimum order quantity.
Contact the factory for details at:
1. Units are available with the leakage current specifi ed at 500 µA max. Contact the factory for more
2. Output regulation includes line & load.
3. 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.
4. A 1% minimum load is required to maintain regulation & ripple specifi cations.
5. Transient recovery is measured to within a 1% error band for a load step change of 50% to 100%.
6. Isolation specifi cations are production HI-Pot tested for 3 seconds.
7. The full output range (see table) is covered in the safety agency certifi cation. Standard models are
factory set to the Preset voltage, but may be set to other levels within the range without affecting
the agency certifi cation. For more information, contact the factory.
8. Output power is given for the factory preset voltage. The maximum continuous output power level
is 400W with 26.85 CFM airfl ow. All models provide a peak power level of 700W for a maximum
duration of 500 µS. For more information, contact the factory.
9. Each unit includes an input fuse (250V/8A). Since this fuse is not fi eld replaceable, it is recommended
that an external fuse of the same size be used on the input of the power supply for protection.
10. The Fan Drive output (at connector CN4) provides 12V/300 mA to drive an external fan.
