Current Sensors
Applications:
For the electronic measurement of currents: DC, AC, pulsed, mixed, with a galvanic isolation between the primary circuit (high power) and the secondary circuit (electronic circuit).

2. Primary current, measuring range IP: +/-75A
3. Supply voltage (+/-5%): +/-12V ~ +/-15V
4. Current consumption: 15mA + Secondary output voltage / loading resistance
5. Overload capacity (1ms): 50x IPN
6. R.m.s. voltage for AC isolation test, 50/60Hz, 1min: 2.5kV
7. R.m.s. rated voltage, safe separation: 500V
8. Isolation resistance @500V DC : More than 1000 megohm
9. Normal output voltage @RL=10,000 ohm, TA=+25°C: 4V
