Current Transducer

FHS 40-P Kit 5 (G2.00.23.104.0)

Evaluation PCB

Connectors Pin-OUT

The board has two single row connectors J1 and J2.

Manufacturer and reference for J1, J2: PRECI-DIP, 310-13-120-41-001001.

Thermal Capability

The enclosed evaluation PCB has tracks with thickness of 70 µm.

The dimensions of the tracks drawn on the evaluation PCB lead to some limitations on the maximum continuous

current which can go through the PCB track.

Remark: under normal operating conditions, temperature of some parts of this product might exceed 70°C.

070201/0 KIT N°5

•

It has the following pin-out:

The four pin one (J1) makes possible to supply the board and access to the output voltage easily.

The two pin one (J2) makes possible to access to the fast output voltage and standby input easily.

Pin #

Standby Standby, Set operating or Standby modes (see datasheet for connection)

Name

OUTFAST

REF

Reference voltage input/output

Output voltage proportional to the current in the PCB track,

Note that the output voltage is positive when the current flows inside the

tracks according to the direction marked “I

0 V

Positive supply voltage 4.75-5.25V; typical consumption 15 mA

(see datasheet for connection)
