User guide for FHS 40-P
Current Transducer
FHS 40-P Kit 9 (G2.00.23.108.0)
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.
070206/0 KIT N°9
It has the following pin-out:
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.
