Current Transducer HXS 20-NP
IPN = 5 - 10 - 20 A
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).
All Data are given with a RL = 10 kW

Notes : 1) It is possible to overdrive VREF with an external reference voltage
between 2 - 2.8 V providing its ability to sink or source approximately
2.5 mA.
