## Overview

The Electronics-Salon Low Voltage Disconnect Module (MD-D1021/24V, Version 2.0) is a panel-mount device designed to protect 24V battery systems by disconnecting loads at low voltage thresholds. Rated for 30A current, it ensures reliable power management and extends battery life, making it an essential component for professional-grade electrical setups.

## Description

The item no paper instructions, please download the PDF file, and before buying please read the file: https://images-na.ssl-images-.com/images/I/81mTLi3gbZL.pdfPart number: MD-D1021/24V, Version 2.0 (from December-22, 2017 change to Version 2.0, Version 1.0 we used a relay as a ON/OFF switch, version 2.0 changed to Ultra low impedance MOSFETs). Mount type: panel mount. Suitable battery: 24V. Rated current: 30A.To protect electronics from damaging low voltages and prevent a deep discharge of a battery during an extended power outage, the LVD module will automatically disconnect the battery when the voltage falls below the user adjustable cutoff voltage. When power is restored the Smart Switch will automatically reconnect the battery. thereby protecting the battery from total discharge (helping to prolong the life of the battery).Applications include: Solar systems, Alarm systems, UPS systems, Mobile systems, Or any application where you need to protect the battery from total discharge.Features： Programmable voltage setting for Disconnect and Reconnect. Red-green LED indication for relay switch ON and OFF. Panel mount or DIN rail mount types selectable. DIN rail mount version can support width 35 / 32 / 15mm rails.

## Customer Reviews

### ⭐⭐⭐⭐ Solder high current 'traces', pic
*by N***F on June 17, 2020*

I ordered this to do LVD for a mower that pulls 20-30 amps. I haven't tested it yet. Here is a cropped pic of the high current carrying pooled solder. One area towards the left contact looks narrow/weak. Any bets? Adding this pic because the seller did not include one of the backside.Update: I ran it for a half-hour without a failure. Grass wasn't long enough yet to push towards 30amps, however. Bumped up 1 star since it didn't fail right off.Update2: After several more uses it is holding up, but still haven't had/made opportunity to load it right up to 30A continuous.Update3: Unit made it through weekly usage through the whole season and Fall cleanup. Calling it good.

### ⭐⭐⭐⭐⭐ Excellent for protecting my electric mower batteries from my kids.
*by J***Y on October 4, 2019*

My kids frequently use my older electric mower with SLA batteries. Despite my adding an LED to indicate when to stop mowing due to battery state, they are accustomed to gas mowers and sometimes take my batteries to near 100% discharge. Adding the LVD, which is much cheaper than even SLA batteries, allows me to "enforce" my instructions on when to stop mowing. Easy to use. Easier if you have a wiring schematic of your device.

### ⭐⭐⭐⭐ Easy to install
*by M***K on June 28, 2019*

I have made reviews on this before. It works well.
