Product description:

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.

First, the 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.

Two, 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;

Three, the implementation of standards

Four, models and parameters

Model input / output pin connection YWG-HSD-1-50A0 ~ 50A/0 ~ 4V 1: positive power supply side 2: negative power supply side 3: output 4: common ground terminal 5: null

Five, matters needing attention

1 power supply and output must be properly connected, not wrong; 2 to two potentiometers, please do not adjust, if you need to adjust, with a small screwdriver slowly rotating to the required precision to 3; the primary bus temperature should not exceed 60 DEG C; 4 when the current bus filled with primary thread hole when the best accuracy is obtained; 5 the use of the environment there should be no conductive dust and gas corrosion and damage to the insulation, the altitude of less than 2500 meters; the 6 measuring DC current, marking the current direction and shell the arrow on the same direction, in order to get positive output.
