Current Transducers HAC 100 ... 800-S
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
Galvanic isolation between primary
and secondary circuit
Isolation voltage 2500 V
Low power consumption
Extended measuring range (3 x
I
PN
)
Advantages
Easy mounting
Small size and space saving
Only one design for wide current
ratings range
High immunity to external
interference.
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)
Derating is needed to avoid excessive core heating at high frequency.
