Current Transducer HXS 20-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).

Features
• Hall effect measuring principle
• Multirange current transducer
through PCB pattern lay-out
• Galvanic isolation between primary
and secondary circuit
• Isolation test voltage 3500V
• Low power consumption
• Extremely low profile, < 11mm
• Single power supply +5V
• Fixed offset & gain
• Insulated plastic case recognized
according to UL 94-V0.
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.
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.
Application Domain
• Industrial
