Shunts are used to measure DC current, produced by the principle of resistance when a voltage is generated across the resistor according to DC current.
Features:
1) Standard for the Installation: IEC 61010-1:1990
2) Accuracy class: 1~4000A: Class 0.5- 0.2
3) Temperature: -40~+60ºC.
4) Relative humidity:
5) Mechanical properties of resistance: can withstand acceleration of 70 m / s ² and impact frequency of 6 hours of 80 to 120 beats per minute transport point earthquake.
6) Overload performance: 120% rated current value, 2 hours.
7) Voltage drop: 50mV, 60mV, 75mV, 100mV, 150mV, 200mV, 300mV and so on.
8) Heat load: Changes in temperature stabilized, does not exceed the rated current of 50A below 80 ºC; rated current of 50A above does not exceed 120 ºC.
Usage:
Shunts are widely used to expand the range of instruments to measure current with a fixed value shunt resistors, precision alloy, can be used in communications systems, electronic machine, automatic control of power supply circuits do limiting, both flow sampling testing.
