Phase Sequence Indicator UПЧФ-1M for AC Systems (38V)

The UPCHF-1M devices are designed to determine the forward and reverse sequence of alternating phases in a three-phase AC electrical network with grounded neutral with a nominal voltage of 380/200 V, frequency 50 Hz, as well as to measure the voltage in AC circuits and resistance. The devices can be used during installation of three-phase phase-dependent electrical consumers, electric motors, pumps, machine tools, three-phase protective disconnection devices and other loads, as well as during adjustment and repair work.
