Product description:

An overview,

Transducer is a kind of alternating current (voltage) can be measured alternating current (voltage) is converted into linear proportion of output dc voltage or dc current instruments, widely used in electric power, post and telecommunications, oil, coal, metallurgy, railway, municipal departments such as electrical devices, automatic control and scheduling system.
Ac current and voltage transducer with a single road, three road combination structure, its characteristic is:
1, high accuracy (typical: 0.2% 0.05%) best.
2, the scope of the whole range has high linearity.
3, high degree of integration, simple structure, good temperature characteristic and long-term stability, the transmitter from regular check.

Five, the wiring diagram
1, YWD series single alternating current (voltage)/three combination alternating current (voltage) transmitter
< , /O:P>
2. YWE series single-phase alternating current (voltage)/three combination alternating current (voltage) transmitter

3. YWF series single-phase alternating current (voltage) transmitter
YWF-I YWF-U

4. YWL series single-phase alternating current (voltage)/three combination alternating current (voltage) transmitter

Note: 1, YWF, YWL series ac current transducer input line from the transmitter punch through the casing, regardless of polarity.
2, YWD, YWE series current transducer is only allowed by less than 10 a current, more than 10 a, can only choose YWF - type 1 product.
Six, product debugging
1, YWD, YWE single ac current and voltage transducer: find the corresponding ZERO corresponds to the transmitter panel and CAL two debugging hole, which of the two potentiometer ZERO and full adjustment potentiometer, respectively, when the calibration with a small screwdriver slowly rotate to the required accuracy.
2, YWD, YWE three combination alternating current and voltage transducer: to find corresponding to the transmitter panel ZEROA, CALA, ZEROB, CALB and ZEROC CALC six debugging hole, including the potentiometer is respectively A and B, C three way of zero and full adjustment potentiometer, calibration with A small screwdriver slowly rotate to the required accuracy.
Seven, installation,
YWD, YWE series used in a DIN rail and screw two installations, width of guide rail is 35 mm.Screw size of 12 and M3 M4 x x 12.YWF, YWL
Use DIN rail installation, guide rail width of 35 mm.
Eight, ordering instructions
When signed a procurement contract, please specify the model, specification, corresponding to the selected type in the following format to fill in, special specifications said in words
In Ming dynasty.

Nine, matters needing attention
1, input, output, auxiliary power wiring must be correct, not misplaced.
2, using the environment should be no conductive dust and no corrosive action on metals, and damage the insulation gas exists, height is less than 2500 meters above sea level.
3, switch products factory has zero and accuracy, please do not adjust.
