Introduction
For systems powered by solar energy, this ATS is an ideal choice.When solar power supply is interrupted due to equipment failure, the switch will immediately detect it and automatically switch to the grid; and when solar power supply returns to normal, it will delay for 2 seconds before switching back, this protects electrical equipment from sudden voltage impact.
It should be noted: that the backup end (mains power) must be kept powered on all the time; otherwise, the automatic switching function will not work properly.
The handle is designed to automatically indicate the power source direction, showing “Source A” when running on solar power, and “Source B” when running on grid power.
The YRO automatic transfer switch is suitable for solar-powered homes, cabins or commercial users, providing both green energy utilization and a reliable backup solution.
Features
- Available in 2P, 3P, and 4P versions to suit single-phase and three-phase applications.
- The operating temperature range is -25°C to +60°C, suitable for various climate conditions.
- With a fast transfer time of just 30 milliseconds, the switch ensures minimal disruption.
Details
- The handle serves as a clear visual indicator of the active power source, aiding in maintenance and inspection.
- It features a special “2-second delay” function that prevents false triggering and stabilizes voltage when switching back to solar.
