Wiring Method of BY83JF Series Intelligent Capacitor Controller
The electrical schematic for the rear panel must be consulted during the installation of the controller since it indicates how the wiring must be done. The wiring method is as follows:
UA, UB, and UC are for connection to the three-phase voltages A, B, and C, respectively, while UN is for connection to the neutral line;
La+, La-, Lb+, Lb-, Lc+, and Lc- are for connection to the three-phase currents A, B, and C;
A and B are for the RS485 communication interface, which can be connected to the communication port of a low-voltage intelligent capacitor.
Note: When all smart capacitors are canceling capacitors, only Lb+ and Lb- are eligible to be connected to the B-phase current line.
Details, just for focusing on high-quality intelligent life
The controller incorporates features so that overvoltage and undervoltage might protect it from any trouble at all. Whenever the supply line voltage goes up or goes unnaturally low due to an overvoltage or undervoltage condition, the controller will automatically cut off the supply line to retain a safe operation of the circuit. Such intelligent protection means equipment can avoid damage through irregularly operating voltages, with certainty and consistency in system operation being established.
A working panel is present on the intelligent capacitor controller. The panel is designed in a simple clear layout, with matching indicator lights for each parameter. So users can easily read and keep monitoring the operational status of the equipment. It is indeed ergonomically intuitive so that the operator will quickly understand working conditions of the equipment thus improving usage and safety.
With respect to the dissipation of heat, the intelligent capacitor controller uses cyclic switching, resulting in none being manual and able to adjust itself for varying application situations. Functional buttons give users the opportunity of easily making the setting of parameters targeting power factor, delay switches, overvoltage protection, number of control loops, current transformer ratio, capacitor position, and rated voltage. Thus, that indeed enhances the versatility of the device and eased operation.
