ACO-MOD-DC 12V DC/DC Step-Down Converter 24V to 12.5V 20A 250W

This industrial-grade DC/DC step-down converter efficiently transforms a 24V DC input into a stable 12.5V DC output, delivering up to 20A and 250W of power for demanding applications. With an efficiency exceeding 90% and passive cooling via an aluminum alloy heatsink, it ensures reliable operation without fans or moving parts. The wide input voltage range of 20V to 30V DC accommodates fluctuations in vehicle or battery systems, while comprehensive protection against overload, short circuit, over-temperature, and reverse polarity safeguards both the converter and connected equipment. Screw terminals provide secure and convenient wiring for input and output connections.

Advantages

High efficiency reduces energy waste and heat generation. Robust protection features enhance system reliability. Compact surface-mount design with passive cooling suits space-constrained installations. Wide input range tolerates unstable power sources. Non-isolated topology offers cost-effective voltage conversion for common-ground systems.
