Voltage Controller
Voltage Controller
Industrial Controls & Drives offers Voltage Controller. ICD AC Voltage Controller is a Protection device for Power System equipments, feeders, and machines against 3 phase system Voltage disturbances. ICD Microcontroller based AC Voltage Controller is designed to measure True RMS voltage of all 3 phase and line voltages. From the samples taken it accurately detect the phase reversal and single phasing. From the measured RMS voltage, unbalance between lines, under voltage and over voltage of each line is computed. All these three parameters are compared with set point, settable in percentage. During fault condition the relay will be deenergized after a definite time delay which is also settable. The 3 line voltages, control settings and time delay are shown on six digit 0.39†seven segment red LED. When the fault has occurred, the display shows respective fault details with readings. Normal operation can be restored by manual reset or automatically when the fault is cleared. This device is designed to operate on SMPS suitable for 90 – 275V AC supply.
