Review on 🔌 Tripp Lite PR12 High-Efficiency 12-Amp DC Power Supply with 120VAC Input and 13.8VDC Output by Eric Nelson

Revainrating 5 out of 5

Good power supply for light loads.

I have a 65 watt 2 meter ham radio transceiver and this 12 amp power supply connected to it for easy use. I had the output power set to medium and had some local repeaters and a simplex frequency programmed into the transceiver. I switched the microphone to the simplex frequency so as not to disturb anyone, and the transceiver display went blank. Even with the "Low Power" setting, the display still went black. So I came up with the idea of separating that 12 amp power supply from the transceiver and replacing it with a 40 year old 20 amp power supply that I have. When I did this and tried to transmit on the same simplex frequency, this time the transceiver worked fine as intended. So if you want to power a 65 watt 2 meter ham radio transceiver for basic use, don't use a 12 amp power supply. It's not strong enough. Choose a power supply of at least 20 amps or maybe more. These transceivers clearly use a lot of power when transmitting. Desperate

Pros
  • Timed automatic overcurrent protection in case of overload
