Current Transducers HTB 50..400-P
and HTB 50..100-TP
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.
2) Operating at ±12V ≤ Vc < ±15V will reduce measuring range.
3) Derating is needed to avoid excessive core heating at high frequency.
