Module13.2-PPS
Description
PPS Module 13.2 is a programmable power supply module. This module employs STEP-DOWN buck technology, supports a wide DC 9-36V input voltage, and integrates an STM32 control processor and AD8418 high-resolution current amplifier. Through high-precision closed-loop control, it achieves a rated output power of 100W (peak 150W) with high-precision current and voltage output, capable of delivering 0.5~30V/0~5A, with a read-back accuracy of ±30mV/5mA. Additionally, the module incorporates isolation chips CA-IS3020S and B0505S-1WR3, providing electrical isolation for both the power supply and the communication bus. The output interface uses standard 4MM banana plug sockets, with a positive and negative pole spacing of 19mm. Each module is calibrated for full-range accuracy before leaving the factory, and users will need to separately purchase a compatible DC power adapter. This module is suitable for use in scientific research experiments, industrial automation, embedded system development, and DIY projects requiring an adjustable power supply.
The maximum output depends on the output capacity of the input DC power supply.
