Current Transducer
Applications:
For the electronic measurement of currents: AC, DC IMPL.,etc.,with galvanic isolation between the primary (high power) and the secondary (electronic) circuits.
Main Technical Data:
1. Primary normal current IPN: 25A r.m.s
2. Primary current, measuring range IP: 0~+/-70A
3. Measuring resistance: RMmin RMmax with +/-12V @ +/-25A max: 54 ohm 360 ohm @ +/-70A max: 35 ohm 52 ohm with +/-15V @ +/-25A max: 54 ohm 470 ohm @ +/-70A max: 35 ohm 84 ohm
4. Secondary normal current: 25mA rms
5. Conversion ratio: 1-2-3-4:1000
6. Supply voltage(+/-5%): +/-12V~+/-15V
7. Current consumption: 12mA+ Secondary output current
8. Isolation test: Between the primary circuit to the secondary circuit(+.-.M):3kVrms/50Hz/1min
Accuracy - Dynamic Performance Data:
1. Accuracy @ IPN, TA=+25¢XC , @+/-15V: +/-0.5%
2. Non-linearity: better than +/- 0.2%
