Current Transducer HXS 50-NP
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.
• Internal & external reference
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.
Application Domain
Notes : 1) It is possible to overdrive VREF with an external reference voltage
between 2 - 2.8 V providing its ability to sink or source approximately
2.5 mA.
2) Excluding offset and hysteresis.
3) Small signal only to avoid excessive heatings of the magnetic core.
