HTB100-P_07 Datasheet, PDF (1/2 Pages) LEM – Current Transducers

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).

Features
• Hall effect measuring principle
• Galvanic isolation between primary
and secondary circuit
• Isolation voltage 2500V
• Low power consumption
• Primary bus bar option for 50A and
100A version for ease of connection
Special feature
• Single power supply from 12V to 15V
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

• Switched Mode Power Supplies
(SMPS)
• Power supplies for welding
applications.
Notes :
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.}
