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 IPN)

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.
