18kW Rack-mounted Load Bank For Data Center

Product Introduction

DC electronic load bank is a high-performance testing equipment designed for simulating real load conditions of DC power sources such as batteries, power supplies, and photovoltaic systems. It provides precise constant current, constant voltage, constant resistance, and constant power modes, ensuring accurate evaluation of power performance and reliability. The system supports programmable control, multiple protection functions, and real-time monitoring of voltage, current, power, and temperature. Widely used in R&D laboratories, manufacturing quality inspection, and industrial production lines, the DC electronic load bank helps engineers optimize power system efficiency and safety. With modular design and flexible configuration, it can be customized according to different voltage and current requirements. Its fast response and high stability make it suitable for aging tests, discharge tests, and long-term endurance testing of DC power equipment.
