RMQ3I-63 / 4P mini dual power automatic transfer switch (referred to as dual power switch), is our daily life is often used in an automatic switching power supply products, the use of a very wide area, the most common is the elevator, fire, Lighting and so on.
RMQ3I-63 / 4P dual power automatic transfer switch Description:
Dual power automatic transfer switch is a new intelligent self-protection dual power switch. The intelligent controller can be detected by keyboard input and LCD display. It can detect the three-phase synchronous detection of common power supply (N) and standby power supply (R). When the motor is connected to 85% of rated operating voltage, For the undervoltage, standby power (R) fault alarm and double points, the computer to deal with the detection results, and then issued a corresponding instruction, the results can be displayed on the LCD display, to the user a good man-machine dialogue interface, the police also Can be manually closed (∨). At present, regardless of the mode of work, the computer detects abnormal data, 3S from the abnormal power supply disconnected into the two-point protection state, the delay (0-30S) to normal power supply.
(N) is automatically returned to the standby power supply (R) power supply, such as the normal power supply (N) return to normal automatically return, such as two working power with the failure, after the computer 3S Will issue a double instruction, the power back to normal work priority.
Working mode: since the vote from the complex for the grid and the grid
Self - resetting for power grid and power grid
Self - resetting and power generation
Built-in power generation and fire protection (DC24V)
★ is simply a way to use all the way to spare, when the sudden power failure or power failure, through the dual power switch, automatically put into the standby power supply, (small load can also be powered by the generator, the device can still normal run. The most common is the elevator, fire, monitoring, the bank with the UPS uninterruptible power supply is also, but his spare is the battery pack. Some of a class of load and two types of load of the factory or most of the units have

Standby power must be enabled when power failure is disabled and power can not be restored for a short period of time. step:

★ remove the mains power supply of the circuit breaker (including the power distribution room control cabinet of the circuit breaker, dual power supply switch box city power supply breaker), pull the double reverse anti-back to the power supply side, keep the dual power switch box Self-powered electric circuit breaker is disconnected.

★ start standby power (diesel generator sets), standby unit is running normally, the order of closed generator air switch, self-power control cabinet of the circuit breaker.

★ one by one to close the power switch box within the standby power circuit breaker, to the load power.

★ During the operation of the standby power supply, the operation duty personnel shall not leave the generator set, and adjust the voltage, plant frequency and so on according to the change of the load.

★ electricity to restore power supply, should do a good job in the power conversion work, cut off the backup power supply, restore the mains power supply.
