LEM HTB300-SP5 Current transducer Datasheet

Current Transducers HTB 50..400-P/SP5
and HTB 50..100-TP/SP5
IPN = 50 .. 400 A
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).

- 25 .. + 85 °C
< 30 (< 36) g
• 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 :
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.
