Current Transducers HTB 50..400-P/SP5
and HTB 50..100-TP/SP5
IPN = 50 .. 400 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).

Notes :
1)
-TP version is equipped with a primary bus bar.
Operating at +12V £ Vc < +15V will reduce measuring range.
Derating is needed to avoid excessive core heating at high frequency.
