* Channel 1 output is linearly derated from 90Vac to 85Vac, 4W per volt to 280W.
** Dc ratings are for specific 60950-1, Non-standard versions only.
All ratings apply for ambient temperatures up to 50°C. From 50 to 70°C the output power is derated at 2.5%
per deg C.
Input Connections: Molex 3 pin header 7A/250V MAX.

* Can be adjusted from nominal at the factory only.
** Peak power of 400W for 10 seconds maximum, maximum rms power of 300W:

Output Limitations:
All outputs are SELV up to and including 48V nominal. Voltages above 48V nominal are non SELV and
therefore all outputs are non SELV and must not be accessible to an end operator.
These products are designed for use with capacitive loads up to the value shown in the Table below.
Applications where a discharged capacitor is switched onto the power supply output creates additional
loading for which a non-standard product may be required if the peak current exceeds the value shown in the
Table below. Consult factory for details.
