HTFS200-P_05 Datasheet, PDF (1/3 Pages) LEM – Current Transducer

Current Transducer HTFS 200..800-P
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).

Notes : ¹⁾ It is possible to overdrive V_REF with an external reference voltage
between 2 - 2.8 V providing its ability to sink or source approx. 2.5 mA.
2) _{Excluding offset.}
3) _{Small signal only to avoid excessive heatings of the magnetic core.}
