myVolts 45 A DC 18-36 V to 13.8 V power supply

Vehicle Radio Power Converter

This DC-to-DC converter steps a vehicle supply of 18 to 36 volts down to a stable 13.8 volts with a tight tolerance of ±0.2 volts. It delivers up to 45 amps of continuous current for mobile two-way radio installations. The unit operates at 80 percent efficiency and includes over-voltage protection that trips at 16 volts ±1.5 volts and over-current protection at 11 amps ±1 amp. Output ripple is specified at 150 millivolts peak-to-peak.

Mobile Installers Needing Regulated 13.8 V

The supply is built for installers fitting walkie-talkies or similar wireless transmitters into vehicles that provide a higher-voltage DC bus. It is not suited for equipment that requires a different output voltage, for systems that cannot tolerate the stated ripple level, or for applications that demand more than 45 amps of output current. Buyers needing AC input or multiple output rails should look at other products.

45 A Continuous Output Rating

The single figure that determines fit is the 45 amp continuous output rating at 13.8 volts. This defines the maximum load the converter can sustain while maintaining its voltage tolerance and protection thresholds. Verify that the connected radio and accessories draw less than this limit under all transmit conditions.
