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).

Notes :

EN 50178 approval pending

≤ Vc < ±15V will reduce measuring range.
