New Product｜Automatic Electronic Phase Switch YX743FPS220

Product Introduction

The YX743FPS220 automatic electronic phase switch is designed to power industrial/home appliances. The three-phase four-wire mains 3x380+N supplies single-phase 220V/50Hz loads to maintain uninterrupted power supply to important single-phase loads and protect them from impermissible voltage variations in the mains supply. To do this, connect the single-phase load to the three-phase supply by plugging in a YX743FPS220. Based on the voltage presence and voltage quality of each phase, the YX743FPS220 will automatically select the best phase and switch the single-phase load power to that phase.

Appliaction Areas

The core advantages of YX743FPS200 automatic electronic phase switching relay are precise phase monitoring, fast switching response and high reliability. Its applications cover many fields such as industry, energy, communications and so on.

01Industrial AutomationIn

industrial automation production lines, equipment such as motors and frequency converters have higher requirements for the stability and accuracy of the power phase. The automatic electronic phase selection relay can monitor the power phase in real time. When there is an abnormality in the phase (such as missing phase, wrong phase sequence), it can automatically switch to the correct phase to ensure normal operation of the equipment and avoid production interruption, equipment damage or product quality defects caused by phase problems.

Application scenarios: production line conveyor belt drive system, industrial robot power supply system, etc.

02New Energy Field

In scenarios such as new energy vehicle charging piles and electric vehicle charging systems, automatic electronic phase selection relays can ensure phase matching between charging equipment and the grid or vehicle power supply, improve charging efficiency and safety, and avoid charging failures or battery damage caused by phase problems.

Application scenarios: power input phase control of DC charging piles, phase matching between AC charging piles and vehicle charging interfaces, etc.

03Communmciations and Date Center

Communication base stations, data centers and other places rely on a large number of precision electronic equipment, which have extremely high requirements on power quality. The automatic electronic phase selection relay can ensure the phase stability of the power supply system, prevent equipment failure, data loss and other problems caused by phase fluctuations or abnormalities, and ensure the normal operation of communications and data centers.

Application scenarios: server power systems, communication equipment power supply lines, UPS (uninterruptible power supply) systems, etc.
