Shunt
Features
Used in combination with a DC ammeter. This high-precision resistor is used to measure electric current by converting it to voltage instead of directly applying the electric current to an ammeter.
Applications
- Measurement of DC current
Specifications
| Class | Class 0.5: Percent error relative to the rated voltage drop between voltage terminals or shunt resistance when current consumption of the instrument is disregarded |
|---|---|
| Rated voltage | 60mV (standard), 100mV (semi-standard) |
| Rated current | 1～7500A |
| Structure | For 150A or less, shunt with base, and for 200A or more, shunt without base |
| Voltage test | 3320V AC for 5 seconds (Applicable to shunt with base only) |
| Insulation resistance | 10MΩ or more with test voltage of 500V (Applicable to shunt with base only) |
- Remark (1)
- For a current shunt, the influence of current consumption of the instrument may not be negligible. For placing an order for a single shunt, adjustments may be required depending on the combined instrument.
- Remark (2)
- The temperature rise limit is designed to be 80˚C at 80% of the instrument current. For high current use with large loss, please be careful when tightening the bus bars.
