Power Supply 

 

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

voltages and currents listed in the following table.

When the current load is outside of the ranges listed, but within each specified output current range, the +5-V, +12-V, and +3.3-V outputs are allowed to 
regulate at +/

10% of nominal DC voltages.  

1

Maximum continuous total DC output cannot exceed 200 W. Maximum continuous combined load on +5-VDC and +3.3-VDC outputs cannot exceed 135 W. 

 

2

Peak +12-VDC output power (up to 12 A) does not exceed 15 seconds in duration. In this condition, the tolerance on the +12-V output is allowed to be +/

–

10%.  

3

In system applications where +3.3 VDC is not used, these values may be 0 A without affecting the regulation on the other outputs.

 

4

The required full load combinations are adjusted so that the total output power is less than or equal to 250 W.
