I. overview
YWG series transmitter for the Holzer effect Holzer effect, transmitter shortcomings of temperature drift, controlled by the compensation circuit can effectively reduce the influence of temperature drift on the measurement accuracy, to ensure the accuracy of the measurement; can the current and voltage measuring arbitrary waveform, according to user requirements to provide standard transmitter output parameters (such as: 0 ~ DC 5V, 1 ~ 5V, 0 ~ 20mA, 4 ~ 20mA), has the characteristics of high precision, convenient installation, low price.
YWG series transmitter Holzer effect 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-HTD-4- - A - / - type current transducer is a primary side and secondary side high electrical isolation, the instrument can be measured, such as the current ripple of DC and AC signal into a DC current or DC voltage output according to the linear proportion. It has the advantages of good temperature characteristics, high linearity, stable performance, products can be up and down switching, easy installation etc..
Three, technical performance indicators
The frequency characteristics of the overload capacity of 2IN 0 ~ 10kHz precision grade < 1.0%NIN insulation 3kVRMS/50Hz/min linearity is superior to 0.2% working environment 0 to 45 DEG C temperature drift is better than that of ± 100ppm/ C ± 12V to ± power supply; 15V; reaction time is less than 100ms flame retardant properties of UL94-VO offset voltage is less than ± the 20mV current is less than ± 0.2mA power supply voltage output ≤ 30mA &le 30mAIM output current;
Four, the implementation of standards
QB/441600 17 113-2002
Five, models and parameters
AC, DC/ type input output DC pin terminal YWG-HTD-4-100A0 ~ 100A/ DC 0 ~ 5V, 1 ~ 5V, 0 ~ 20 mA and 4 ~ 20 mA 1: is working on a power supply terminal 2: negative working power port 3: measurement output 4: common ground end YWG-HTD-4-150A0 ~ 150A/ DC 0 ~ 5V, 1 ~ 5V, 0 ~ 20 mA, 4 ~ 20 mAYWG-HTD-4-200A0 ~ 200A/ DC 0 ~ 5V, 1 ~ 5V, 0 ~ 20, 4 ~ 20 mA mAYWG-HTD-4-300A0 ~ 300A/ DC 0 ~ 5V, 1 ~ 5V, 0 ~ 20, 4 ~ 20 mA mA
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.
