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.
