Functions

The 100 Watt Power Supply Module is a rack-mountedunit that plugs directly into a 48-pin backplanemounted connector in the leftmost slot in the rack. It

provides +5 volt, +12 volt and -12 volt power, and logic

level sequencing signals to the backplane.

This power supply may be used either in a single rack

application, or may also be used to provide power to a

second rack if the total load is within the supply rating.

Interconnection to the second rack is through a prewired cable (see the ordering instructions on the last

page of this data sheet)The power supply output will ride through a one-cycle

total loss of input power at full load. Protection is provided for overcurrent and overvoltage fault conditions.

Operation of the Power Supply

This Power Supply Module can operate from either a

120 voltor 240 volt nominal line (this is jumper selectable, as illustrated on page 3). For these two ranges, the

power supply can accept an input voltage range of from

90 to132 VAC or from 180 to 264 VAC, 47 to 63 Hz.Overvoltage Protection

The power supply includes an electronic overvoltage

protection circuit. This circuit will turn the output off

if the 5 volt bus exceeds 6.2 +0.5 V. The power supply

must be turned off to be reset. External overvoltage

on the output that triggered the overvoltage protection will not cause the power supply fuse to open.

However, if an internal fault in the power supply

caused the overvoltage condition, the fuse may open.

Replace this fuse with a 3AG 3 amp, 250 volt fuse.
