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.
