Current Transducer HTB 50 .. 400 - P
and HTB 50 .. 100 - TP
For the electronic measurement of currents: DC, AC, pulsed...,
with a galvanic isolation between the primary circuit (high power) and
the secondary circuit (electronic circuit).

2 pins of Ã2mm diameter are available on transducer
for PCB soldering
Notes : 1) -TP version is equipped with a primary bus bar.
2) Operating at ±12V ⤠Vc < ±15V will reduce the measuring range.
3) Derating is needed to avoid excessive core heating at high frequency.
Features
ââ Hall effect measuring principle
ââ Galvanic isolation between
primary and secondary circuit
ââ Isolation voltage 2500 V
ââ Low power consumption
ââ Wide power supply: ± 12 ..15 V
ââ Primary bus bar option for 50
A and 100 A version for ease of
connection
Advantages
