查询HTB100-TP供应商
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).

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.
Ambient operating temperature -20 .. +80 °C
Ambient storage temperature -25 .. +85 °C
2 pins of Ø2mm diameter are available on transducer
for PCB soldering.
