3-Phase Voltage Monitor

ICM450 T HREE -P HASE V OLTAGE M ONITOR Stop Motor Burnouts! Programmable 3-phase line voltage monitor with 25-fault memory, high temperature LCD display, easy setup & clear, diagnostic readout of system faults, 190 to 630 VAC operation... The ICM450 was specifically designed to protect motors and other 3-phase loads from premature failure and damage due to common voltage faults such as voltage unbalance, over/ under voltage, phase loss, reversal, incorrect sequencing and rapid short cycling. www.DataSheet4U.com Mode of Operation At power up, the ICM450 evaluates the incoming power for proper phase sequence, amplitude, and symmetry (voltage unbalance). If the three phase input at the line side connections is within user-set parameters, the load energize LED is turned on and the internal relay is energized. Continuity will be across terminals 4 and 6. If connections are made to the load side terminals, the ICM450 will transfer monitoring over to the load side only. When a critical fault condition (phase loss or phase reversal) is present, the relay will immediately de-energize, the loadenergized LED will turn off, the fault LED will flash, and the fault is written to memory. Continuity will be across terminals 4 and 5. If a non-critical fault condition (unbalance, high or low voltage) is present, the ICM450 will ignore it during the interrogation delay time. If it is still present following the interrogation delay time, the relay will de-energize, the load-energized LED will.
