SCAs the control core of low-voltage capacitor compensation, the series reactive power automatic compensation controller (i.e. low-voltage power factor compensation controller) can effectively improve the serious impact of nonlinear, asymmetric, and impulsive loads on the deterioration of power quality in the power distribution network; To achieve the goal of making the distribution power factor in the control area meet national standards through automatic compensation of reactive power, thereby improving the power quality and transmission capacity of the power grid. And significantly reduce electricity costs by reducing and eliminating reactive power losses for power users.

The product uses internationally advanced microprocessors, integrated circuits, and high-quality components produced by professional manufacturers at home and abroad, with a high-strength flame-retardant engineering plastic shell. It has the advantages of simple structure, high integration, high precision, high reliability, super strong anti-interference ability, as well as beautiful appearance and small volume. According to user needs, products can be divided into square shapes based on their appearance（SC-812Type and rectangle(SC-912type)Two models; Divided by working voltage, there are220Vand380VTwo voltage specifications; In terms of controlling the number of cutting paths, there are also4、6、8、10、12There are five specifications of roads.

Functional features:

1.Equipped with wiring phase judgment function, making installation and debugging simple and convenient.

2.When adjusting controller settings parameters and testing relay operation, there may be no current signal.

3.It can dynamically display the real-time power factor of the distribution system, and automatically monitor and handle both over compensation and under compensation of the power grid.

4.It has overvoltage monitoring, display, and protection functions, and can quickly cut off the compensation capacitor when it is greater than the overvoltage protection setting value. The total cutting time is less than60Second, to ensure the safe use of the capacitor bank. The overvoltage protection setting value can also be adjusted by the user according to the situation.

5.The switching delay of capacitors in the same group is greater than180Seconds; Switching delay of capacitors in different groups10～120Users can set it themselves in seconds.

6.There are monitoring, display, and locking functions for ultra small loads (undercurrent) in the distribution system to prevent capacitor switching oscillation. The undercurrent protection value has been set at the factory, and users can also choose to adjust it themselves.

7. Independent output unit1～12Roads are optional and do not affect each other; The output circuit adopts a cyclic working mode of first connect, first disconnect, and first connect; At the same time, the output circuit can be configured with multiple channels according to user needs（1～9The road is a fixed compensation, and several roads are automatically compensated.

Conditions of Use:

1. Altitude not exceeding2500rice.

2. ambient temperature-5
