12 Steps Power Factor Controller 100V Single Phase Power Factor Relay 300kvar digital power factor control panel with 300 kvar

- Dynamic Response time: D type ≤20 milliseconds, J type ≤1 seconds.
- Protection: overvoltage / undervoltage protection, harmonic voltage overload protection.
- Communication: optional RS485 communication interface, support for MODBUS protocol.
- Polarity reverse protection: automatic identification phase sequence of the current transformer secondary side. User free to reset the phase sequence in controller screen without exchange wiring.
- Intellengent work modes: cycle switching with intelligent switching logic. When the volume of the capacitor are different in each step, controller will automatic re-culculate the best switching mode.
- Screen display: total harmonic voltage and current (THD), voltage, current, power factor, active power, reactive power, frequency, etc.
- Electromagnetic Compatibility: EFT group pulse test, 4000V Class A (the most advanced international standards); strong anti-jamming capability.
