Regenerative DC Electronic Load ANMEL(F)

ANMEL(F) Series Regenerative DC Electronic Load is designed for R&D validation and production line aging testing of AI server power supplies, meeting the core requirements of fast current transient response, long-term load stability, and automated integrated test benches. It features high current rise rates, dynamic loading, and multiple communication options.

The ANMEL(F) series overcomes the shortcomings of conventional regenerative electronic loads, such as insufficient current rise rate that fails to simulate server startup transients (leading to test misjudgment), and the heat dissipation pressure and electricity costs associated with energy-consuming loads. It offers a high current rising rate (programmable current slew rate) to emulate the steep current edge during server startup, and high-efficiency energy regeneration that feeds the power from the device under test back to the grid, significantly reducing heat dissipation and electricity costs in aging production lines. It is an ideal choice for AIDC power supply testing.
