Automatic Transfer Switch, 3/4 Pole, 6 to 63 Amps

Features

• Suitable for 3-phase power system with rated operating voltage 400V AC 50Hz, ratings from 6 to 63 amps
• With the function of normal power ON, dual OFF, standby power ON
• Simple structure, practical, easy operation, no noise, small impact, and long service life
• Wide applications, suitable for the illuminating circuits of commercial buildings, shopping mall, banks, and high-rise buildings where the fire protection are needed.

ATS Structure & Working Principle

• Structure
  The automatic transfer switch consists of two miniature circuit breakers, motor, controller, and driving mechanism. The miniature circuit breaker with high-breaking capacity is used, and ATS has the same performances as MCB.
• Working Principle
  The controller of ATS will detect two loops of power supply. When one loop has fault, the ATS controller will give a logic decision and send a command of closing and opening the related miniature circuit, to ensure the safe and reliable power supply.

Tips: What's dual power automatic transfer switch?

The automatic transfer switch (ATS) is a switch to transfer between two power sources. It is constituted by one or several change-over switching equipment and other necessary apparatuses. It is used to detect the power circuit. In addition, it changes over one or several load circuits from one power supply to the other power supply.

For the use of dual power automatic transfer switch, briefly, it is connected with one utility power and one backup power. When the utility power suddenly fails, it will be transfer to the backup power supply automatically through the ATS (at the small load, the backup power supply can be supplied by the generator) to enable the equipment to operate normally. The most common application is the elevator, fire protection and monitoring. The condition is the same to the UPS uninterruptible power supply of the bank. However, its backup is the battery set. It is used in some factories and mines or units with loads of class I category and class II category.
