SKU CH-JTMM-T2JDF

A relay module that switches power from 5 V up to 48 V and provides automatic UPS cut-off protection

  • Wide input range from 5 V to 48 V
  • Power-off protection prevents damage during outages
  • Automatic switching keeps circuits running
  • Emergency cut-off stops power instantly

Vszerda 5V–48V Relay Module

This Vszerda relay module provides automatic power switching and emergency cut-off protection for circuits operating between 5 V and 48 V. It is designed for hobbyists and engineers who need a compact UPS-style safeguard in custom electronics projects. The board detects supply loss and disconnects the load to prevent damage during unexpected outages.

Input range decides compatibility

The module accepts a supply voltage from 5 V up to 48 V, so it suits low-voltage DC systems within that window. Builders whose equipment runs below 5 V or above 48 V must choose a different protection device because this board cannot operate outside its rated range.

Highlights

Questions about this item

What does the 48 V rating mean when this module is installed in my system?

The 48 V rating is the maximum supply voltage the relay contacts can switch. Your load voltage must stay at or below 48 V for safe operation.

Which interface or standard governs the relay switching, and what does it limit in practice?

The module uses a 5 V control signal to drive the relay coil. The coil voltage caps the control side at 5 V, while the contacts are rated up to 48 V on the load side.
