Overview
Tripp Lite PR series DC power supplies convert standard 120 Volt AC (VAC), 60Hz power into
regulated 13.8 Volt DC (VDC) power; (12V DC output, nominal). PR series models are ideal for
powering a wide range of equipment designed to run on 12V DC power. PR series models can
also be used as general-purpose test bench power sources.
BATTERY CHARGING NOTE
DO NOT use PR series models rated at 12 amps and lower for battery charging. If you connect
a battery to any of these models with the unit NOT plugged into a live 120 Volt AC outlet or the
unit plugged in but turned OFF, you may burn out the unit because of reverse current flow.
You MAY use PR series models rated at 15 amps and higher for battery charging. However, the
battery must be separately fused with a fuse not greater than the value of the unit’s nameplate
amperage rating. Otherwise, the battery can cause current flow greater than the unit’s
amperage rating back into the unit under certain circumstances and may burn out the unit.

Installation
Features
Solid State Integrated Circuit: Provides excellent voltage regulation to within ±0.5V;
output voltage is maintained from 0 to 95% of full load
Crowbar Overvoltage Protection: Prevents overvoltage surges from damaging
connected equipment (15 amp and larger models)
High Quality Filtering: Provides low-noise operation, excellent for sensitive
communications 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 7 amp and larger models
Heavy-Duty Power Transformer: Provides complete line isolation and robust load
handling.
Large Heat Sinks and Vented Cabinet: Provides cool, continuous operation and long
component life
Compact, Attractive Design: Size and color harmonize with all modern communications
equipment; narrow front profile conserves operating space
Common Ground and Battery Minus Bonded: Contributes to low noise operation
Power Supply Installation
Place your PR power supply in a well ventilated location. Note: The unit will generate heat as it
operates, especially if used at or near its current output limits.
WARNING!
Hazardous voltages are present inside the unit. DO NOT expose the unit to rain
or moisture. Unit should only be used in a dry, indoor, protected environment.
Operating Environment: Temp 0 to 40 Degrees C, 0 to 95% humidity (Non-
Condensing)
CAUTION!
DO NOT block the louvers on PR models. Allow at least 2” above the top of the
PR cabinet for ventilation. The compact, space-saving design of the PR 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. Please store the unit in a clean and suitable environment
and keep it cleaned regularly with a dry cloth.
Equipment Installation
Place your equipment next to your PR model power supply.
Note: 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 2” clearance for the equipment to rest on.
The PR models’ louvers are intentionally designed to prevent direct installation of equipment
on top of them.
