Product description:

I. overview

The utility model relates to an active power transmitter and a reactive power transmitter, which is a direct current or a DC voltage which is converted into an active and reactive power output in a linear proportion. And can reflect the transmission direction of the measured power. The utility model is suitable for various single-phase, three-phase three wire and three-phase four wire systems, and can be widely used in electrical devices of petroleum, post and telecommunications, metallurgy, railway, municipal, electric power and other departments.

Six, product debugging

1, single or single active reactive power transducer: open the corresponding to the transmitter on the panel corresponding ZERO and CAL two rubber plug, the two potentiometers were zero and full scale adjustment potentiometer adjustment, with a small screwdriver to slowly rotate to the desired accuracy can be.

2, active power and reactive power combined transmitter: open the corresponding ZERO1, ZERO2, CAL1 and CAL2 four rubber plug panel corresponding to the transmitter, the four potentiometers were zero and full scale and zero reactive power and active power full adjustment potentiometer, with small adjustment screwdriver slowly rotating to the required precision.

3, the factory has been adjusted zero and precision, please do not adjust.

Seven, ordering information
