I. Introduction

Energy-consuming electronic load bank adopts high-frequency switching technology and air-cooled heat dissipation mode, which can realize over-temperature, under-voltage, over-voltage, over-current and other protection functions.

The load adopts the circuit design and control module with independent intellectual property rights of Sunwin, which can achieve the effect of maintaining constant power and constant current in the process of 10-800V input voltage test of fuel cells in a wide range. The test has high accuracy, strong pertinence, complete functions, and reliable safety. It can perform multiple tests and inspections on fuel cells. The system has high integration and can complete the setting and inspection of all test links on a unified software.
