= 0 - 20 mA
= 4000..20000 A
Features
Hall effect measuring principle
Galvanic isolation between primary
and secondary circuit
True-rms, 0-20mA DC current output
Isolation voltage 12kV~
Low power consumption
Package in PBT meets UL 94-V0
Advantages
Easy mounting
Small size and space savings
Only one design for wide current
ratings range
High immunity against external
interference
Applications
Battery supplied applications
Uninterruptible Power Supplies
(UPS)
Power supplies for welding and
telecommunication applications.
Notes :
1)
Pollution class 2, overvoltage category III, reinforced insulation
2)
Linearity data exclude the electrical offset.
3)
Please refer to derating curves in the technical file to avoid excessive
core heating at high frequency
4)
Please consult characterisation report for more technical details and
application advice.
