Product description:

1, 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. 2, technical performance index of frequency characteristic measurement range of 2IN 0 ~ 10kHz 20IN insulation 2.0kVRMS/50Hz/min overload 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 is less than ± ≤ 30mA temperature drift is better than that of ± 100ppm/ C flame retardant properties of UL94-VO reaction time less than 10us built-in power surge, reverse polarity protection; 3, the implementation of the standard QB/441600 17 113-2002 4, the types and parameters of model input / output pin terminal YWG-HSD-4-100A 0 ~ 100A/0 ~ 4V 1: is working on a power supply terminal 2: negative working power supply terminal 3: output measurement 4: common ground end YWG-HSD-4-150A 0 ~ 150A/0 ~ 4V ~ YWG-HSD-4-200A 0 200A/0 ~ 4V ~ 300A/0 ~ 4V 5 YWG-HSD-4-300A 0 Note 1) power, the output must be properly connected, not wrong; 2) for the two potentiometers, please do not adjust, if you need to adjust, with a small screwdriver slowly rotating to the required precision; 3) the primary busbar temperature should not exceed 60 DEG C; 4) when the current the bus filled the primary thread hole, 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; 6) measuring DC current, marking the current direction and shell the arrow on the same direction, in order to get positive output.
