HVD100 is a voltage protection module of 3 phase 3 wires, when the voltage occur over voltage, under voltage, miss phase, send out a free voltage output.
 
PERFORMANCE AND CHARACTERISTICS
Monitor one source 3 phase voltage.
Monitor over voltage, under voltage, miss phase.
The point of over voltage, under voltage is adjustable.
The timer of voltage abnormal delay is adjustable.
The output is a relay free voltage contact.
Module structure design, ABS plastic crust, rail installation, plug connector, convenient maintenance.
