36V 48V 60V 75V to 5V 20A Isolated Buck Converter, High Current DC-DC Voltage Regulator 100W with Reverse Protection, Galvanic Isolation Power Supply Module

This 36-75V to 5V 20A isolated DC-DC step down converter is a high-power professional voltage regulation module, specially designed for 48V industrial power conversion scenarios. It supports ultra-wide input voltage range from 36V to 75V, perfectly compatible with 48V, 60V common power systems, and stably outputs 5V 20A large current with maximum 100W constant power supply, meeting the power demand of high-load equipment and engineering projects.

Adopting strict galvanic isolation design between input and output, this 48V to 5V buck regulator effectively isolates circuit interference, suppresses voltage ripple, and enhances the stability of the rear-end electrical system. Built-in premium reverse polarity protection function, it can intelligently prevent module burnout and equipment damage caused by wrong positive and negative wiring, greatly improving the safety of field installation and use.

Made of high-quality original electronic components and thickened flame-retardant PCB board, the power conversion module features high conversion efficiency, low heat generation and strong durability. It supports long-term continuous stable operation without voltage drop, current surge or frequent failure, suitable for long-time working industrial environments.

Compact structure with simple wiring and convenient installation, the isolated DC-DC regulator has wide compatibility. It is widely applied in communication equipment, monitoring power supply, storage battery power system, industrial control equipment, DIY power transformation, automation modules and more 48V to 5V step-down power supply scenes.
