Why Buy?

DC Power Supplies allow one to power devices that commonly run on 12V DC such as two way radios, amplifiers, car/marine stereos, etc... in your home or shack to use the radio as a base station. Be sure to choose a model with sufficient amperage to run your devices. 3-6A for a standard AM CB Radio. 12-18A for a Stereo or SSB / 10M Mobile radio. 12+A for use with Amplifiers. Refer to your devices owners manual or look up specifications if unsure.

Quick Specs

Step up your base station with the Pyramid PS12KX, a heavy-duty, RF-quiet power supply. This is a Linear power supply, using a robust transformer to deliver exceptionally clean and stable 13.8V DC power. Its noise-free output makes it a favourite for CB, GMRS, and Amateur Radio operators who demand a clear, interference-free signal.

With 10 amps of continuous power (12A peak), the PS12KX is the perfect workhorse for running 25W to 50W mobile radios, or for powering a CB radio and multiple other accessories without straining. If you need a reliable, no-nonsense power source that won't inject noise into your receiver, this is it.

  • 📻
    RF-Quiet Linear Design: Provides extremely clean and stable 13.8V DC power, eliminating the RF interference and "hash" common with cheap switching supplies.
  • ⚡️
    10 Amp Continuous Power: Delivers 10A continuous and 12A peak (surge) current, ideal for powering most 25-50 watt mobile radios.
  • 🔌
    Heavy-Duty Output Terminals: Features solid, rear-panel red/black binding posts for a secure, high-current connection for your radio equipment.
  • 🛡️
    Fully Protected: Built-in thermal and short-circuit protection safeguards your connected gear. Features an illuminated front-panel power switch.

⚠️ Power Limitations: Check Your Radio

A typical 50-watt mobile radio draws approximately 10-12 amps when transmitting at full power. This supply is a perfect match for that use.

It is NOT recommended for high-power 100W HF radios (like an Icom 7300 or Yaesu FT-891), as they require 20-25 amps. Using this supply with a 100W radio will cause it to shut down on transmit.

Nice power supply, but...

I would have given it 5 stars if it actually had a cooling fan in it as is described in the listing. Otherwise, it works fine.

Amazing

Great power supply for ham radio and super low noise level. Never had an issue with over/under current. Great product and pyramid seems to be ok as well with customer support/warranty

Nice Unit, clearly well constructed.

I like the fact that it is constructed of metal, no plastic shells. Very sturdy and a lifetime investment if used properly. Supplies Linear power. Compared to Plastic "Brick" switching power supplies, it has a simple design, dissipates excess power through its metal shell and is capable of high thermal stress.

So far so good

Needed more 13.8V 10A power supplies for one of our physics labs. They seem to be just as advertised, but I'll update if we have any issues.

Works as Described

Works great. Puts out the amperage I needed without fail. It's actually the second one I bought. Was pleased with the first so I picked up another.

Good, reliable unit.

Works well, no overheating. I like the fact that it's quiet, both sound wise and electrical.I use it in my ham radio shack, and there is no electrical interference. Some transformers make an awful amount of static on the line when in use. This one is quiet.

Great value

We’ve ordered these before for powering our ionic foot baths. Great output at a great price.

At 50% Load, 5 Amps, this power supply gets very hot. limit 10 A to 15 min.

This power supply was advertised has having a built-in cooling fan. Mine came without any fan, and there is no evidence of provisions made for mounting one. The power transistors and finned heat-sink on the back of the unit get very hot, and there is alarming heat build-up within the case. I have ordered several cooling fans to add to the power supply, then it will become a noisy power supply instead of a quiet hot one.

Good Power Supply

This is a solid power supply. 10 amp, 12 amp surge. The voltage readout on my ham radio shows 13.8 volts. Good value for the money.
