Introducing the PwrBlock 323: A Versatile USB-C PD Power Supply for Automated Testing

Everypin, a Finnish company, has launched the PwrBlock 323, a cutting-edge programmable USB-C PD power supply designed for automated test fixtures. This innovative device can deliver a voltage range of 1 to 32V and a maximum current of 3A, providing up to 92W of power from a 100W USB-C PD source.

The PwrBlock 323 is engineered for seamless integration into testing setups, allowing it to be mounted within test jigs or stands. It features software-controlled power switching, voltage and current measurement, and power cycling capabilities for devices under test (DUT). This product adds to the growing list of programmable lab power supplies, joining the ranks of other notable options like Ampisu, PocketPD, and BenchVolt PD.

Key specifications of the PwrBlock 323 include an STMicro STM32G0C1CEU Arm Cortex-M0+ microcontroller, dual USB Type-C ports for power and control, and a 10-pin IDC USB control connector for linking to a host computer or test controller.
