HXS20-NP_12 Datasheet, PDF (1/3 Pages) LEM – Current Transducer
Current Transducer HXS 20-NP
For the electronic measurement of currents: DC, AC, pulsed...,
with galvanic isolation between the primary circuit (high power)
and the secondary circuit (electronic circuit).

Notes:
1)It is possible to overdrive VREF with an external reference voltage between 1.5V -
2.8V providing its ability to sink or source approximately 5 mA.
Application domain
2)Maximum supply voltage (not operating) < 6.5 V
3)Excluding Offset and Magnetic offset voltage
●● Industrial.
4)Small signal only to avoid excessive heatings of the magnetic core.
5)UL recognized with surrounding temperature until +85℃
