The company specializes in producing double power automatic switch, good quality and low prices. 
 KBQ1 series one, an introduction to intelligent dual power supply requirements with the reliability of power supply have become more sophisticated, with a two-way power on many occasions to ensure reliability of supply. When the normal power supply anomalies, intelligent dual-supply device can automatically switch to standby power, is this intelligent dual-power supply unit in reliability between the two power switches to ensure power supply devices. In hospitals, hotels and mines, which are widely used. Intelligent dual-power supply unit from the switch body and the controller of two parts. Switch body by a motor controlled by a mechanical interlocking mechanism commonly used in power circuit breakers and circuit breaker backup power division and then control the power switch. Sampled by the controller to determine the power supply voltage is abnormal, if there is an exception should result in a corresponding switch. Second, the intelligent dual-power supply dual power supply controller action processing There are four control modes, automatic recovery mode recovery mode since the vote of no fire and the generator from the ways. Since the vote from the double way: If the commonly used power deviation is detected, then automatically convert the load from normal power to the standby power supply; if the normal power supply back to normal, then automatically returns the load for receiving the common power supply. Since the compound since the vote of no way: If the commonly used power deviation is detected, then automatically convert the load from normal power to the standby power supply; if the common power is restored, can not automatically return for receiving the load normal power supply. Unless an exception only for backup power conversion. Fire: If the Fire and Rescue Service issued a fire command DC24V, dual power in any mode will cut off two-way power to the load. Generator: If the commonly used power deviation is detected, the issue of power generation command request. When the power voltage reaches the rated voltage, start with the load circuit power off, automatic conversion to electricity supply; when the normal power supply is back to normal, then they automatically return for receiving the normal power supply and power to issue instructions, the request to stop power generation. Third, the scope KBQ1 series intelligent double-power automatic switching system for AC 50/60Hz, rated voltage of 1000V rated current 1250A the following dual power supply system, to achieve common power supply (N) and standby power (R) between automatic switching (also can be set manually switch) to enable users to achieve dual power supply unattended substation. This product is suitable for special classes, Ⅰ type electric power systems, high-rise buildings, residential areas, military facilities, hospitals, airports, terminals, shopping centers, communications, fire control, metallurgy, chemicals, textiles, petroleum, coal and other important places do not allow power
