This programmable module is a versatile power supply module that has STEP-DOWN buck technology and supports a wide DC input voltage range of 9-36V. It integrates an STM32 control processor and an AD8418 high-resolution current amplifier. With high-precision closed-loop control, it provides a rated output power of 100W (peak 150W) and provides precise current and voltage outputs, capable of delivering 0.530V/05A with a read-back accuracy of ±30mV/5mA.

Additionally, it has isolation chips CA-IS3020S and B0505S-1WR3, providing electrical isolation for both the power supply and the communication bus. The output interface utilises standard 4MM banana plug sockets with a 19mm spacing between the positive and negative poles. A compatible DC power adapter must be purchased separately. This module is ideal for industrial automation, embedded system development, and DIY projects requiring an adjustable power supply.

Note: The maximum output depends on the output capacity of the input DC power supply.
