Three-Phase Voltage Monitor Comes In SMT Packaging

The TVM Series three-phase voltage monitor is the company’s first to be encapsulated in a 2” x 2” surface-mountable package. Connections are made by means of 0.25” quick-connect terminals. The unit may also be mounted to 35-mm DIN rails using an optional adapter.The unit continuously measures the voltage of each of the three phases and senses under- and over-voltage, voltage unbalance, phase loss and phase reversal. Protection is provided even when regenerated voltages are present. Trip points and time delays are factory fixed and calibrated with no user adjustments required. Trip delay is from 0.3 to 100 s and restart delay is from 0.3 to 1000 s. The unit’s isolated SPDT output relay contacts are rated for 10A resistive and can be used to switch motor contactor coils and other control voltage loads.
