HTB50-P_12 Datasheet, PDF (1/3 Pages) LEM – Current Transducer

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 Ø2mm 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.
