1202300028 is a commonly used device for power control.As the demand and reliability of electrical equipment become more and more demanding, it is not easy to use traditional methods when controlling the power on and off. This device can be used to control the power on and off of the equipment, thus avoiding the trouble of manually controlling the power, and ensuring the reliable on and off of the equipment.

1202300028 can be divided into two types: DC type and AC type. The DC type can control DC power, and the AC type can control AC power. The working principle of the device is also different. The DC type adopts a static transfer switch (STS) control, which is suitable for small and medium-sized loads. The AC type adopts a static transfer switch (STS) + static frequency converter (SFC) control, which can be used for large loads such as refrigeration systems and air conditioning systems.

The STS in the DC type needs to be in a power failure state first when the power is turned off, and then the power is turned on. The SFC needs to match the frequency with the normal power supply before switching to supply power. When the device is used, the user only needs to pay attention to the parameters of the STS and the safety requirements. The device is easy to use, and its power consumption is usually less than 5 watts.

The working principle of the AC type 1202300028 is more complicated. The STS + SFC is mainly used here. At the same time, the sensor and actuator are needed. When the circuit is broken, the STS will detect the state and then send a signal to the actuator. The actuator then sends a signal to the SFC to start it. At the same time, the frequency of the SFC is adjusted according to the frequency of the normally powered power supply. After the adjustment is completed, the SFC will send a signal to the actuator to control the STS switch, and then the STS switch completes the switching between the two power supplies, so as to realize the purpose of reliable power on and off.

1202300028 is widely used in many fields. In electricity dispatching and control, it can be used for line switching, shutdown, short circuit protection and protection against overload; in the military industry, it can be used for the control of weapons and air defense radar power on and off; in industrial production, it can be used for power supply switching of instrumentation, control automation devices, computers and other equipment; in lighting control, it can be used to switch on and off the lights in commercial buildings, stadiums, and entertainment venues.

In addition, 1202300028 can also be used in medical care and home automation, and has a wide range of applications. It is a reliable device for power control, and is widely used in various industries and fields.
