10A 20A 50mV 75mV Voltmeter Ammeter Electric Welding Machine
DC Current Shunt Resistor
There are too many models of the shunt, please consult before place order. thank you.
The catalouge will be sent you check.
The main technical parameters:
1, accuracy level: 2 ~ 4000A; 0.5: 5000 ~ 10000A; 1 level.
2, the ambient conditions: -40 ~ +60 ℃, relative humidity ≤ 95% (35 ℃).
3, overload performance: rated current 120%, 2 hours.
4, the voltage drop: 50mV60mV70mV100mV
5, the load under the heat: temperature stability tends to change, the rated current 50A the following does not exceed 80 ℃; rated current 50A or more does not exceed 120 ℃.
Precautions:
(Or copper) and the shunt connection is not allowed to have artificial contact resistance, the sampling point of the secondary voltage can not be sampled from the non-sampling point.
Actual use of the current (long) is recommended not to exceed 80% of rated current.
