Function Introduction:
1. This controller is used forPower quality monitoring deviceThe automatic adjustment can control the automatic switching of 12 sets of capacitors based on the set target power factor. In the automatic switching mode, there are two control methods: simple control and complex control.
2. Capable of manually controlling the input and output of capacitors, used for self inspection of 12 sets of capacitors during factory testing, as well as quick capacitor removal.
3. Adopting power factor and reactive power composite control to ensure reliable operation at low loads and avoid switching oscillations.
4. In the automatic switching mode, the output circuit adopts a cyclic working mode of first on, first off, and first on (simple control). You can also perform capacitor switching actions (complex control) based on the set number of capacitor switching groups and switching sequence. In the manual switching mode, the output circuit operates in a sequential manner of first making, then breaking, and first breaking, first making.
5. The large screen Chinese LCD display has a simple and intuitive interface, making it easy for users to set relevant parameter values through panel buttons, achieve human-machine communication, parameter settings, and have memory function.
6. The instrument measures and displays system frequency, voltage angle, current angle, active current, reactive current, voltage effective value, total voltage distortion rate, 2-25th harmonic voltage content, current effective value, total effective value of harmonic current, 2-25th harmonic current effective value, active, reactive, and comprehensive power factor in real-time, and provides leading or lagging indication.
