Dual power transfer switch

Overview

Automatic Transfer Switch (ATSE) is an automatic transfer switch that integrates switch and logic control, truly realizing mechatronics integration. It is suitable for industrial and commercial distribution equipment with AC 50Hz, rated voltage up to 440V, and agreed heating current up to 1600A. It has functions such as voltage detection, communication interface, and electrical mechanical interlock; It can achieve fully automatic, remote control, forced "0" setting, emergency manual operation, and is widely used in the automatic conversion of the main power supply and backup power supply of the power supply system, or the automatic conversion and safety isolation of two load devices. The switch is managed by various logical commands issued by the control circuit board to control the motor. The motor drives the operating mechanism of the switch body to quickly connect and disconnect the circuit or perform circuit conversion, achieving safe isolation through obvious visible states.

Switch structure description

◆ Electrical key lock: Control the power supply of the internal control circuit of the control switch. When the electrical lock is turned on, the switch can achieve fully automatic, operation control, and strong "0" operation. When the electrical lock is turned off, the switch can only be manually operated.

◆ Operating handle: When manually operating with the operating handle, the electrical lock must be turned off first.

◆ Mechanism padlock: For maintenance purposes, first use the operating handle to place the switch in the "0" position, then connect the padlock mechanism and lock it on before conducting maintenance (connecting the padlock will cut off the internal control power supply of the switch, and the switch cannot be automatic or manually operated).

Indicator: Indicate the working status position of the switch (l, 0, II).
