## Overview

The MARSTEK Automatic Transfer Switch is a compact, DIN rail-mountable device designed for seamless, automatic switching between mains power, generator, and inverter sources. Rated for 63 amps and 120 volts, it features adjustable voltage thresholds and switch timing, plus multi-layer protection against overcurrent and voltage irregularities. Its five LED displays provide real-time monitoring of voltage and current, making it ideal for RVs, trailers, and backup power setups seeking reliable, hands-free power management.

## Description

[Automatic Transfer Switch]: This automatic transfer switch allows simultaneous connection to mains power, generator, and inverter. It automatically switches to the next power source when the primary power supply fails or the voltage exceeds the set range.

Review: Works perfectly. Nice design. - Installed this in my older motorhome that had no switch or inverter (manually plug it in to shore power or generator). I installed an inverter then wired this in with generator and shore power now everything is beautifully automatic. I like its nice compact design too. it's much nicer than anything else I could find on desertcart.
Review: Good data display and three supply option - Mount this in a Circuit Breaker Distribution Box (likely need an 8 DIN) and you have a pretty cool RV autocrossover with voltage readout. Very functional, and programmable. I mounted mine right over my breaker panel in my trailer conversion. Nice to have any sources plugged in all the time, inverter, generator, and city, and it tells me what is on and selects the best one. What more could you ask for. Many RV's overcomplicate this for hundreds, tons of weight and no data readout.

## Features

- [Automatic Transfer Switch]: This automatic transfer switch allows simultaneous connection to mains power, generator, and inverter. It automatically switches to the next power source when the primary power supply fails or the voltage exceeds the set range.
- [Flexible Settings]: This three-way automatic transfer switch enables you to freely prioritize mains power, generator, and inverter. You can set the voltage threshold for switching, so it automatically switches when there is under-voltage or over-voltage. The switch speed can also be set within the range of 1s to 600s, with a default of 30s.
- [Multiple Protection for Safe Power Usage]: Provides protection against under-voltage, over-voltage, and over-current, ensuring the safety of your electrical devices.
- [LED Display]: This automatic transfer switch features five LED screens that provide real-time voltage readings for each power source, as well as the voltage and current of the currently used power source, allowing convenient monitoring of the circuit conditions in real time.
- [Adjustable Parameters]: The transfer time, reset time, over/under voltage protection, and overcurrent protection parameters are all adjustable within the specified range.

### ⭐⭐⭐⭐⭐ Good data display and three supply option
*by R***. on October 28, 2023*

### ⭐⭐⭐⭐ If this had a short delay it would be perfect.
*by C***R on July 5, 2025*

I was excited to find an ATS with three inputs instead of two, but the shortest switching delay (programmable) is 1 second. My original plan was to use this switch to connect devices that sensitive to power interruptions through this switch so that when the grid voltage dips, as it frequently does during storms, it would automatically switch to another source. Switching delay notwithstanding, this is a fantastic programmable switch.
