TSMQ2-125 Double Power Automatic Changeover Switch

Basic Information
  1. Model TSMQ2-125

Product Description


TSMQ2-125 modular double power automatic changeover switch is used to provide the power supply for circuit constantly when the main power supply is not available suddenly. The switch is suitable in power supply system with 50/60Hz, rated voltage up to 415V and rated up to 125A.
When the product works under automatic mode, the switch converses the circuit from the main power supply (Ⅰ) to standby power supply (Ⅱ) automatically in case the main supply power is off (or phase failure). When the main power supply (Ⅰ) resumes to be available, the switch converses the circuit back to main power supply (Ⅰ) from standby power supply (Ⅱ) automatically.
When the product works under manual mode, the changeover of circuit between main power supply (Ⅰ) and standby power supply (Ⅱ) should be realized manually.
The switch is characteristic of small in volume, prompt in reaction, reliable in conversion, convenient in installation and long life in service.
