Definition
The “NT25-P”current transducer for the electronic measurement of currents: AC, DC, IMPL.,etc.,with galvanic isolation between the primary (high power) and the secondary (electronic) circuits.
Electrical data:
1. Normal current IPN: 25A rms
2. Measuring range Ip: 0~+/-80A
3. Analog output voltage: @Ip 2.5+/-(0.625xIp/ IPN)V
@Ip=0 2.5V
4. Number of secondary turn (+/-0.1%): 2000
5. Load resistance RL: not less than 2000 ohm
6. Internal measuring resistance RIM (+/-0.5%): 50 ohm
7. Supply voltage (+/-5%): +5V
8. Current consumption( at +5V): 28+Is+(Vout/ RL) mA
9. Isolation: Between primary and secondary: 3kV rms/50Hz/1min
