F&F CKF-319 TRMS Manuals

- 1 - CKF-319 TRMS Phase loss and phase sequence sensor The CKF-319 phase loss and phase sequence microprocessor sensor without neutral wire is designed to protect electric motor powered from the three-phase network in following cases: » voltage loss in at least one phase; » voltage drop in at least one phase below 150 V; » voltage increase in at least one phase above 280 V; » voltage asymmetry between phases above the set value; » incorrect phase sequence. The sensor correctly measures the true rms value of the voltage (TrueRMS), even when the power supply voltage is (disturbed) distorted. Purpose F&F Filipowski sp. j.
