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

Features: 

1) SVR power monitor is a new type high-tech patented product employing 

    digital integrated circuit of large scale

2) It is mainly applied in the circuit with AC being 50/60Hz and rated 

    voltage being below 250V, and is to provide relay protection for 

    single-phase electromotor of over-high voltage and over-low voltage

3) It is surely a good partner with which electromotor can work in great 

    safety



Specifications:  

1) Optional protection for over-high voltage

2) Optional protection for over-low voltage

3) Wide range of surrounding temperature: -25oC - 65oC

4) No effect from load current intensity, laden nature, impulse and etc.

5) Measures up to GB/T14084.5 eqv IEC60947-1:1999 standard 

6) Unique encapsulation ensures monitor to work under high humidity

7) 20 outputs with control and alarm

8) Directly independent installment or HT 35 guideway installment
