Power Factor Controller

ICD Power Factor Controller PFC 9070 is micro-controller based and assembled in 144 x 144 mm ABS plastic enclosure for flush mounting. It operates with voltage and current signals from suitable voltage and current transformers. It measures power factor and also the reactive power consumption of the load. With appropriate user program fed, it gives relay output signals to switch IN/OUT capacitor banks by contactors in a sequential manner to achieve the preset PF.

• Measurement of PF for all 4 quadrants
• Identification of the power of connected
• capacitor either automatically or through user program
• Optimum usage of capacitor banks through cyclic switching
• Control either in Auto / Manual
• Suitable for switching in / out capacitor through thyristor module / Contactor
• Adjustable connection delay and reconnecting delay for banks to suit the load changes
• Alarm against Over Voltage, Under Voltage, Over Current, Over Compensation, Under Compensation & Step fault
• THD Measurement and alarm (optional)
• Alarm for insufficient measurement current
• Disconnection of particular step for step problem
• Disconnection of capacitor bank for excessive harmonics
• Connection of permanent capacitor value in addition to the measured required power E.g: for compensation of a transformer
• Separate PF setting for EB/DG (optional)
• External potential free digital input provided to select EB/DG Setting (optional)
• RS485 Port for communication with MODBUS RTU protocol (optional)
