Current Transducers HTB 50 .. 400-P
and HTB 50 .. 100-TP
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 : EN 50178 approval pending
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.
