Product description:
I. overview
YWG series Holzer effect sensor can measure the current and voltage of arbitrary waveform, the output can truly reflect the input current or voltage waveform parameters. Aiming at the shortcomings of the Holzer sensor temperature drift, is controlled by the compensation circuit can effectively reduce the influence of temperature drift on the measurement accuracy, to ensure the accuracy of the measurement; has the characteristics of high precision, convenient installation, low price.
YWG series Holzer effect sensor is widely used in inverter, inverter, UPS power supply, communication power supply, electric welding machine, electric locomotive, transformer substation, CNC machine, electrolytic plating, microcomputer monitoring, network monitoring and detection of current and voltage isolation facilities.
Two, principle
YWG-HSD series current sensor is a kind of sensor with a high degree of electrical isolation between the original side and the secondary side, which can reflect the measured DC, AC and pulse currents. The utility model has the advantages of fast reaction time, strong overload capacity, good temperature characteristics, continuous adjustable output, stable performance and the like.
Three, technical performance indicators
The measuring range of 2IN frequency 0 ~ 10kHz 20IN overload capacity insulation AC2.0kV/min· 1mA precision grade <1.0%IN working environment 0 to 45 DEG C, the linearity is superior to 0.2% ± power supply; 12V ~ ± 15V, +12V, +15V offset voltage is less than ± 20mV power consumption ≤ 30mA temperature drift is better than that of ± 100ppm/ C flame retardant properties of UL94-VO reaction time is less than 10us built-in power surge, reverse polarity protection;

Six, matters needing attention
1 power supply, the output must be properly connected, can not be wrong;
2 for the two potentiometers, please do not adjust, if necessary, with a small screwdriver slowly rotating to the required accuracy can be;
3 the temperature should not exceed 60 degrees;
4 when the current bus is filled with the original threading hole, the best measurement accuracy is obtained;
5 the use of the environment should be no conductive dust and non corrosive metal and the destruction of insulating gases exist, altitude less than 2500 meters;
6 when the DC current is measured, the direction of the current is the same as that of the arrow on the shell of the product.
