NDQ2 series dual power automatic transfer switch with improved detection protection, it uses high-speed single- chip microprocessor as the main chip embedded, real-time detection of power supply status, power supply system to ensure reliable operation of high speed.
1. Mechanical interlock and electrical interlock with the double protection to prevent the closing of two circuit breakers at the sa me time.
2. With Manual control Automatic recovery Common power supply Standby power Power button again Since the vote of no self-re-6 operation control method.
3. With under voltage, over voltage, phase loss protection function to prevent the power supply to load fault.
4. A power failure, circuit breaker trips, such as failure of the alarm or indicator.
5. Secondary function of preventing reclosing The load side short circuit, overload, automatic switch off electrical appliances (tripping), you can not automatically switch on th eir own.
6. With the operational parameters (under voltage, over voltage, sub-gate delay value, closing delay value) adjustable setting.
7. The interface with the fire, emergency situations, as long as access to fire control DC24V (control voltage selected by the user),the controller will immediately cut off contact output control.
8. With RS485, RS232C serial communication interface, the application communication protocol MODEBUS.
