charging. If you connect a battery to any of these models with the unit
plugged into a live 120 Volt AC outlet or the unit plugged in but tumed
you may bum out the unit because of reverse current flow.
You MAY use
battery charging. However, the battery must be separately
not greater than the value of the unit's nameplate amperage rating. OtherÂwise, the battery can cause current flow greater than the unit's amperage
rating back into the unit under certain circumstances and may bum out the
unit.

DC; output voltage is maintained from
Crowbar Overvoltage Protection: prevents overvoltage surges from damaging con-
nected equipment (15 amp and larger models).
High Quality Filtering: provides low-noise operation, excellent for sensitive commu-
nications receivers (0.1 to 0.15 volts maximum ripple).
Current-Limiting Electronic Foldback: automatically limits current and voltage
outputs in case of overload; time-controlled on
Heavy-Duty Power Transformer: provides complete line isolation.
Large Heat Sinks and Vented Cabinet: provides cool, continuous operatio; and long
component life.
Compact, Attractive Design: size and color harmonize with all modem commdnica-
tions equipment; narrow front profile conserves operating space.
Common Ground and Battery Minus Bonded: contributes to low noise operation.

has been made possible by careful placement of the cabinet louvers and
design of the external heat sinks, to provide adequate internal cooling for
long life and reliable performance.
If you are installing a radio transceiver or other equipment directly on top of PR models,
you must construct a small raised shelf with at least

Plug the power suppty line cord into a
switch on the front panel. The switch body (or indicator light on smaller models) will
illuminate RED, indicating the power supply is functioning properly. Turn the connected
