Notes:
1. Output regulation includes line & load.
2. Ripple & noise is measured from 10 Hz to 20 MHz. Connec-
tion to the unit is made with a 0.1 µF ceramic capacitor and
a 22 µF electrolytic capacitor connected in parallel.
3. A 1% minimum load is required to maintain regulation and
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 220W without providing 26.85 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 an input fuse (T8A/250V). 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.
Models with other output voltage levels
are available (i.e. 15 VDC, 36 VDC, etc)
