HKZ reactive power compensation controller
Product description
It is suitable for compensation control of three-phase unbalanced load. It can realize full split phase compensation, full common phase compensation, total complement and split complement mixing and compensation. The number of sub-compensation and co-compensation is set by the user. The sub-compensation can be set to 3, 6, 9, 12, and 15 channels. The number of sub-complementary channels is arranged in the front, such as 123 and 456. The total number of supplementary channels is arranged in the rear. When the number of sub-compensation channels is set, for example, 6 channels, the default after the 7th channel is co-compensation. The output mode: static, 220V relay contact, with AC contactor switching capacitor. Dynamic (Type D), internal DC voltage output, with load switch, reactive power regulator
Or the power cross block controls the physical quantity: reactive power, and takes into account the target power factor. Protection function: overvoltage protection, undervoltage protection.
Manual switching: Supports manual switching of capacitors. Power contribution mode: cyclic switching and coding switching, coding 1111, 1222, 1233 or 1244 can be set. LCD Chinese characters display: voltage, current, power factor, active power, reactive power of each phase. Frequency, etc. Electromagnetic compatibility: Class A of 4000V anti-EFT group pulse test (the highest level of international electrical standard rough Ec). Need to connect three-phase four-wire voltage sampling signal and three-phase current transformer sampling signal.
