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).

Advantages
• Small size and space saving
• Only one design for wide current
ratings range
• High immunity to external
interference.
Applications
• AC variable speed drives
• Static converters for DC motor drives
• Battery supplied applications
• Uninterruptible Power Supplies
(UPS)
• Switched Mode Power Supplies
(SMPS)
• Power supplies for welding
applications.
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.
