HTB50-P_07 Datasheet, PDF (1/2 Pages) LEM – Current Transducers

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).

2 pins of Ø2mm diameter are available on transducer
for PCB soldering.
Features
• Hall effect measuring principle
• Galvanic isolation between primary
and secondary circuit
• Isolation voltage 2500V
• Low power consumption
• Wide power supply: ±12V to ±15V
• Primary bus bar option for 50A and
100A version for ease of connection
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)

(SMPS)
• Power supplies for welding
applications.
Application domain
• Industrial
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.}
