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).

Standards
EN 50178: 1997
2 pins of Ø2mm diameter are available on transducer
for PCB Prototyping soldering.

Industrial
Notes :
-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.
