Features:
1) TVR (Three phase power monitor) is a high-tech patent product
which is used to the large-scale digital integration
2) Tests the wave-form, the amplitude, and the phase of the voltage
by PC to judge whether anything wrong with it or not
3) The TVR is applied to the AC 50/60Hz and the rating voltage under
460V
4) It provides the relay protection for the over voltage, the under
voltage, the opposite phase, the chopping phase and the three
phase voltage imbalance of electromotor input power
