myVolts DC18V-36V Input 13.8V Output 45A Power Supply

SKU CH-Q93N-N96W1

Compact DC-DC converter steps 18-36 V vehicle power down to a regulated 13.8 V ±0.2 V at 45 A with over-voltage and over-current protection for mobile radios

  • TypeAT
  • Wide 18–36 V input suits vehicle electrical systems
  • Stable 13.8 V ±0.2 V output powers two-way radios reliably
  • 45 A continuous current handles high-draw transmitters
  • Over-voltage and over-current protection shields connected equipment
  • 80 % efficiency reduces heat and extends service life

DC-to-DC converter for mobile radios

This compact silver unit steps a vehicle’s DC18V-36V supply down to a regulated DC13.8V±0.2V rail rated at 45A. It is intended for installers who need clean power for two-way radio equipment in cars or trucks.

Critical voltage match for transceiver safety

The output sits at 13.8V with a tight ±0.2V tolerance and ripple of 150mVP-P, while over-voltage protection triggers at 16V±1.5V and over-current protection at 11A±1A. Select this supply only when the radio’s spec sheet calls for exactly that nominal voltage and current envelope.

Simple chassis mount with protection caveats

The metal case measures 13×8.5×5 cm and weighs roughly 488g, allowing direct mounting in a vehicle cavity. Ensure the input source stays within the 18V-36V window and that wiring can handle the 45A load; the built-in protections guard the radio but will not prevent damage from reversed polarity or an undersized feed.

Questions about this item

What does the 45 A output rating mean when the supply is running a radio in a vehicle?

The unit can deliver up to 45 A at 13.8 V ±0.2 V, so it will power a high-draw two-way radio continuously as long as the vehicle system stays within the 18 V–36 V input range.

How does the DC 18 V–36 V input range limit what power sources I can use?

It accepts any DC source between 18 V and 36 V, and the 80 % efficiency figure means roughly one-fifth of the input power becomes heat, so the source must handle the corresponding current draw.

What physical space and mounting points does the 13 × 8.5 × 5 cm metal case need?

The supply measures 13 cm long, 8.5 cm wide and 5 cm high, weighs about 488 g, and its metal chassis can be secured with screws or brackets that match those outer dimensions.
