Introduction 

The HC5F family is for the electronic measurement of DC, AC or pulsed currents in high power and low voltage automotive applications with galvanic isolation between the primary circuit (high  power)  and  the  secondary  circuit  (electronic  circuit). 

The HC5F family gives you the choice of having different peak currents (from &plu*n; 200 A up to &plu*n; 900 A) in the same housing. 

Features

●  Open Loop transducer using the Hall effect

●  Low voltage application

●  Unipolar 5 V DC power supply

●  Primary current measuring range up to &plu*n; 300 A

●  Maximum rms primary current limited by the busbar, the

Principle of HC5F Family

The  open  loop  transducers  use  an  Hall  effect  integrated circuit.

The magnetic flux density B, contributing to the rise of the Hall voltage, is generated by the primary current IPto be measured.

The current to be measured IP is supplied by a current source i.e. battery or generator (Fig. 1).

Within the linear region of the hysteresis cycle, B is proportional to:

The Hall voltage is thus expressed by:

magnetic core or the ASIC temperature T° < 150°C

●  Operating temperature range: - 40°C < T° < 125°C

●  Output voltage: full ratiometric (sensitivity and offset)

Therefore:

= constant (b) xIP

●  High speed transducer.
