Current Transducer HTFS 200..800-P I
PN
= 200 - 400 - 800 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 R

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.
LEM reserves the right to carry out modifications on its transducers, in order to improve them, without previous notice.
