The power supply is capable of operating at input voltages
F.Y.I.
of below 85 Vrms or between 132 and 180 Vrms without
damage. However, at these voltages it is possible for the
power supply to shut down.
The power supply has three output voltages which can be either
switched or nonswitched. The following table lists the available
power supply output voltages.

If the power supply should shut down, restart it by turning
F.Y.I.
the system off and then on.
Any output can indeÞnitely withstand a short circuit without
damage or stress to the power supply. However, a short circuit
causes the power supply to shut down. When a short circuit occurs
it must be removed. By powering down the system, the AC input
voltage is recycled. When the system is powered on, normal
operation can be resumed.
