The module enables unidirectional AC and DC current measurement over a range from 0 A to 65 A. XtremeSense™ TMR technology, an electrically isolated current path, 1 MHz bandwidth, and an analogue voltage output support use in systems requiring fast current measurement and high dV/dt immunity. Pololu CT433-HSWF65DR Large Carrier 0–65 A, 3.3 V
Device Pololu CT433-HSWF65DR Large Carrier uses the Allegro CT433-HSWF65DR sensor intended for unidirectional current measurement. The module requires a supply voltage from 3.0 V to 3.6 V, while the output voltage is 0.65 V at 0 A and increases by 30.8 mV for each ampere of current. 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 support M6 screws, ring terminals, or wires up to 4 AWG. During testing, the manufacturer achieved approximately 55 A continuous current at an ambient temperature of around 25°C without forced-air cooling. For average currents above 30 A, temperature monitoring and additional cooling should be considered.
