HTB100-P Datasheet, PDF (1/2 Pages) LEM – Current Transducers HTB 50~400-P/SP5 and HTB 50~100-TP/SP5

Current Transducers HTB 50 .. 400-P/SP5
and HTB 50 .. 100-TP/SP5
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.}
