Power Supply DC Connector Pin Assignments

The 250-WpowersupplycanoperatefromanACpowersourceof115VACor230VACat50–60 Hz. The power supply provides the DC operating voltages

and currents listed in the following table.

Outputs will meet and not exceed SELV requirements per electrical standards, for example UL 60950, IEC 60950, EN60950 PAR.2.3.

Maximum continuous combined load on +5 VDC and +3.3 VDC outputs will not exceed 150 watts.

Peak +12 VDC output power (up to 17.0 amps) will not exceed 15 seconds in duration. Under this condition, tolerance on the +12v output, is allowed to be

+/- 10%.

+5 VDC minimum load will be 0.2A when there is a minimum load of 0.3A on the +12 VDC and 0.42A on the +3.3 VDC outputs simultaneously. +5V min load

is 1A for load transient tests.

In system applications where +3.3VDC is not used, all other outputs will stay within regulation while the +3.3 VDC output is in a zero load condition.

NOTE: The +3.3 VDC output wires (orange) must be 16 AWG. All other output wires must be 18 AWG.
