myVolts Switch Mode Power Supply DC18V-36V Input 13.8V 45A

SKU CH-0MHY-QWV37

A DC-to-DC converter delivering 13.8 V at 45 A from an 18-36 V vehicle supply with over-voltage and over-current protection

  • TypeAT
  • Stable 13.8 V output protects sensitive radios
  • 18–36 V input range suits vehicle power systems
  • 80 % efficiency reduces heat and power draw
  • 150 mV ripple ensures clean DC for clear audio
  • Metal casing and 488 g weight aid durability

Vehicle Radio Power Supply

This myVolts switch-mode unit converts a DC18V-36V vehicle input to a regulated DC13.8V±0.2V output at 45A. Built-in over-voltage protection at 16V±1.5V and over-current protection at 11A±1A guard connected walkie-talkies from damage. The metal chassis measures 13 x 8.5 x 5 cm and weighs approximately 488g.

Mobile Radio Installers

Installers fitting two-way radios into trucks, buses or mixed-fleet vehicles gain a compact, high-efficiency converter that tolerates a broad input span. The 80% effective rate and 150mV ripple suit voice-grade transmitters, while the AT form factor fits standard mounting points. Buyers needing AC mains operation, multiple output voltages or telecom-grade redundancy should look elsewhere.

Critical Spec 45A Output Current

The 45A continuous rating decides whether this supply can drive your radio stack; exceed it and the 11A±1A protection will trip. Match the radio's peak draw to this figure before purchase, as no parallel or higher-current variant is described.

أسئلة حول هذا المنتج

How much heat or noise does the 45 A output produce during continuous use?

The unit runs at 80 % effective rate with 150 mV P-P ripple, so waste heat is limited and there is no fan listed in the specifications.

What must I already have to connect this supply to my two-way radio?

You need a vehicle or battery source that delivers 18 V to 36 V DC and a cable with the correct polarity for the radio's DC input.

Will the 13.8 V ±0.2 V output work with older radios that expect a fixed 13.8 V rail?

Yes, the tight ±0.2 V regulation and 16 V ±1.5 V over-voltage protection keep the rail within legacy radio tolerances.
