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.
