Vehicle DC Converter for Two-Way Radio

This compact switch-mode power supply converts a vehicle DC input of 18-36V into a stable 13.8V output at 45A for mobile two-way radios. It is designed for operators who need reliable DC-DC conversion in automotive installations.

Check Vehicle Voltage and Radio Current Draw

Verify that your vehicle electrical system stays within the 18V to 36V input range and that your radio does not exceed the 45A continuous output rating. The unit provides over-voltage protection at 16V±1.5V and over-current protection at 11A±1A, so confirm these thresholds suit your equipment.

Metal Enclosure with High Efficiency

The silver metal housing measures 13 x 8.5 x 5 cm and weighs approximately 488g, offering rugged mounting for mobile use. An 80% effective rate and low 150mV ripple help keep radio operation clean during daily driving.

Questions about this item

What comes in the package and do I need extra cables or connectors?

The box contains the power supply unit only; input and output wiring must be sourced separately.

How do I choose between the input and output ratings for my vehicle setup?

Feed it 18–36V DC from the vehicle and it delivers a steady 13.8V±0.2V at up to 45A for the radio.

What does the 150mV ripple figure mean for my two-way radio in practice?

The low 150mVP-P ripple keeps transmitted audio clean and prevents noise on sensitive receiver circuits.
