Four small green circuit boards with digital displays and terminal blocks

Generic Logic, Inc.

Generic Logic, Inc. 12V-36V DC Voltage Protection Module Pack of 4

SKU CH-RXV4-90ENG

Protects 12-36 V DC batteries from over-discharge with an adjustable cut-off relay and ±0.1 V accuracy

  • Prevents over-discharge with automatic cut-off at preset voltage
  • Relay switching handles DC 12-36 V input range
  • Settings retained after power loss for seamless restart
  • Simple two-button factory reset shows 888 on screen
  • Compact board measures 4.33 x 3.94 x 0.59 inches

DC Voltage Protection Module Pack

This pack contains four identical 12V-36V DC voltage protection modules designed to guard batteries against over-discharge. Each unit uses a relay to switch the load on and off without altering the supply voltage. The modules suit lead-acid, lithium-ion and solar panel batteries but are not intended for battery packs. Builders maintaining off-grid or backup power systems will find them a practical fit.

Adjustable Cut-Off and Recovery

Users can set a disconnect voltage and a separate reconnect voltage, with the default at 12V and a 2V difference value. A digital display shows readings to ±0.1V accuracy and flashes 888 when factory defaults are restored by holding both buttons during power-up. Settings survive unexpected power loss so the module resumes its protective role immediately. Power draw stays below 1.5W.

Board Dimensions and Current Limits

Each board measures 4.33 x 3.94 x 0.59 inches, giving a compact footprint for enclosure mounting. The relay handles the stated maximum current for the 12-36V input range, making the module suitable for moderate loads such as lighting, sensors or small inverters. It will not support high-current applications like large motor starters or heavy DC-DC converters.

Questions about this item

What maintenance does the digital low-voltage protector require after installation?

The module retains user settings during power loss and can be reset to factory defaults by holding both buttons while powering on, so no routine maintenance is needed beyond occasional voltage checks.

What limit is reached first when the relay switches continuously under load?

The relay handles switching up to the maximum current rating; sustained operation at that limit will hit the contact endurance before the <1.5 W control circuit or the ±0.1 V accuracy drift.

How much heat and power does the pack of four modules draw when running all day?

Each board consumes under 1.5 W, so four units stay below 6 W total with minimal heat rise, and the relay-only output adds no extra conversion loss.
