Rated at 63 amps and supporting customizable voltage and timing settings, it ensures uninterrupted power supply with advanced protections against overcurrent and voltage fluctuations. Featuring a clear 5-LED display for real-time monitoring, it’s ideal for RVs, cabins, and smart power systems seeking reliable, intelligent energy 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: Great device reasonable price works well - Easy to install works well seamlessly switches between land solar and generator power Have now purchased three of these units. They work flawlessly I would recommend them to anybody that upgrading the power system for the cabin on an RV. Is
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*

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.

### ⭐⭐⭐⭐ 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.
