Wide Input 13.8V 5A DCDC Step Down Module

A dedicated 13.8 V DC power solution for systems operating from elevated DC bus voltages, this step down converter supports 18–90 V DC input — certified for reliable operation with 60 V and 72 V battery architectures. It provides a fixed, low-noise 13.8 V output capable of delivering up to 5 A continuously, with built-in protections including input undervoltage lockout, output overcurrent limiting, and thermal shutdown. The module uses a low-EMI synchronous rectification design and features a reinforced isolation barrier rated to 1500 V DC for safety-critical applications. Physical dimensions are 76 × 52 × 24 mm with screw-terminal inputs/outputs and a metal baseplate for direct heatsinking. Weight is 210 g. No external components are needed for basic operation — making it ideal for both new designs and field retrofits where time-to-deployment and reliability are prioritised over customisation. Use cases include powering 13.8 V amateur radio stations from electric vehicle batteries, supplying instrumentation in 72 V industrial automation cells, and energising emergency lighting controllers in solar-powered remote monitoring stations — wherever stable, code-compliant 13.8 V must be derived from higher-voltage DC infrastructure.
