5A 75W DC-DC Step-Down Power Supply Module with Voltmeter

This is a 5A DC-DC adjustable step-down power supply module designed for applications where input voltage exceeds output voltage. It features dual button voltage adjustment, onboard voltmeter with input and output indicators, and one-key emergency stop for instant power cutoff.

The module delivers up to 75W output power (recommended within 50W) with continuous voltage adjustment from 1.2V to 32V, supporting input voltages from 5V to 36V. High conversion efficiency reaches 96%, with load regulation of 0.8% and overheating plus short-circuit protection built in.

Set your preferred power-on state (ON or OFF by default), and all parameters are retained when power is cut. The compact design (66 × 39 × 18mm, 33g) suits DIY projects, adjustable power supplies, vehicle systems, and industrial voltage reduction—common applications include 12V to 5V, 24V to 12V, and 36V to 24V conversions.

Plastic housing with durable, tested construction. Recommended operation within 4.0A for optimal performance; higher loads require enhanced cooling. Slight colour variations may occur depending on display settings and lighting conditions.
