Description

Device Pololu CT433-HSWF50DR Large Carrier uses the Allegro CT433-HSWF50DR sensor intended for unidirectional current measurement. The module requires a supply voltage from 3.0 V to 3.6 V, while the voltage at the VOUT output is 0.65 V at 0 A and increases by 40 mV for each ampere. The output is non-ratiometric, so the zero point and sensitivity remain independent of the actual supply voltage within the permitted range.

The six-layer PCB with 2 oz copper supports heat dissipation during high-current operation. Connection holes with a diameter of 6.6 mm and a spacing of 22 mm allow the use of M6 screws, ring terminals, or wires up to 4 AWG. The actual continuous current capability depends on ambient temperature, connection method, and cooling, so for average currents above 30 A, the manufacturer recommends monitoring the sensor temperature and considering additional cooling.
