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 overload capacity of 2 0IN insulation 2.0kVRMS/50Hz/min precision grade <1.0%IN working environment 0 to 45 DEG C, the linearity is superior to 0.2% working power of ± 12V ~ ± 15V offset voltage 20mV power consumption less than ± ≤ 30mA & plusmn temperature drift is better than 100ppm/ DEG C; flame retardant properties of UL94-VO reaction time is less than the surge, 10us built-in power reverse polarity protection;

Four, the implementation of standards

Six, matters needing attention

1, the power supply, the output must be properly connected, can not be wrong;

2) for the two potentiometers, please do not arbitrarily adjust, if necessary, with a small screwdriver slowly rotating to the required accuracy can be;

3. The temperature of the original bus shall not exceed 60 degrees centigrade;

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.
