LoadBlock is a programmable electronic load module for automated testing, validation, and production systems. It provides controlled loading of DUT power outputs in CC, CV, CR, and CP modes in one compact hardware module.

It handles loads up to 60 V, 10 A, and 100 W and is designed for integration into automated test fixtures and production environments. LoadBlock shares the same mechanical, software, and system architecture as Pwrblock, allowing both modules to be used within the same test platform.
