Purpose and Audience

The Tripp Lite PR7 converts 110 V AC mains into a regulated 13.8 V DC output rated at 7 amps. It is built for technicians and installers who need a compact, continuous-duty bench supply for 12 V nominal equipment such as mobile radios, security panels or test gear.

Who It Suits and Who It Does Not

The unit fits users who require TAA-compliant hardware with automatic time-controlled overcurrent protection and an illuminated on/off switch. It is not suited for applications demanding higher amperage, adjustable voltage, multiple output channels or battery-backup functionality.

Sustained Load Behaviour

Large heat sinks and a vented cabinet allow continuous operation at the full 7-amp rating while maintaining output within 95 % of the no-load value. The supply measures 4.3 inches high, 5.5 inches wide and 9.5 inches deep, weighing approximately 7.40 lb.

Questions about this item

What AC voltage must my wall outlet provide for the PR7 to convert to 13.8 V DC?

The unit accepts 110 V AC input and delivers a regulated 13.8 V DC output at up to 7 A.

Will the PR7’s automatic overcurrent protection interfere with older 12 V radio equipment that draws brief peak currents?

The built-in time-controlled overcurrent protection trips only on sustained overload, so short peaks from legacy gear are handled without shutdown.

How can I verify the PR7 is delivering its regulated 13.8 V DC after I switch it on?

The illuminated on/off switch lights when the unit is powered, and the regulated output holds at least 95 % of the no-load voltage under load.
