Vehicle Radio Power Supply

This AT-type DC-DC converter steps a 18 V to 36 V vehicle bus down to a steady 13.8 V ±0.2 V at up to 45 A. It is built for mobile two-way radio installations that need clean, regulated power from a truck or car electrical system.

45 A Continuous Output Current

The unit delivers 45 A maximum, making it the single figure that determines whether your radio and accessories can run together without voltage sag. Over-current protection trips at 11 A ±1 A, so sustained loads above that level will shut the supply down.

Handles Typical Mobile Rigs Comfortably

At 80 % efficiency and 150 mV p-p ripple, the converter runs most single-transceiver setups with headroom for a speaker or GPS. It reaches its limit when multiple high-power radios or linear amplifiers are keyed simultaneously, pushing demand past the 45 A rating.
