24V to 13.8V Car Walkie-Talkie Power Supply Transformer 45A

24V to 13.8V Car Walkie-Talkie Power Supply Transformer 45A

Power your car walkie-talkie and other 13.8V devices reliably with this high-performance DC-DC transformer. Designed for automotive use, it converts input voltages from 18V to 36V down to a stable 13.8V ±0.2V output, delivering up to 45A of consistent current for uninterrupted communication and operation.

This transformer offers high efficiency (≥80%) and low ripple voltage (≤150 mVP-P), ensuring stable power delivery for sensitive electronics. With minimal source and load effects (2×10⁻³), it provides dependable performance under varying vehicle conditions. Built-in overvoltage (16V ±1.5V) and overcurrent (11A ±1A, self-recovering) protection safeguards both the transformer and connected devices.

Ideal for vehicle-mounted communication systems, emergency equipment, and mobile electronics, this DC-DC transformer ensures safe, efficient, and reliable operation. Compact and easy to install, it provides a professional-grade solution for powering 13.8V devices from a 24V car battery or similar power sources.
