With over a decade of experience in manufacturing power testing equipment, RST Electric has launched a high-performance 36kw 380v Liquid Cooled Load Bank. It is specifically designed for precise testing scenarios in data centers, laboratories, and telecommunications rooms, which have strict requirements for noise, space, and energy consumption. It is a new generation of silent, energy-efficient, and rack-mounted power testing equipment that replaces traditional air-cooled load boxes.

RST Electric, as a professional manufacturer and source supplier of Braking Resistors for Industrial Control in China, has developed the 20kW Braking Resistor to address the industry pain point of frequent deceleration energy feedback from frequency converters, servo systems, and industrial motors. This product can efficiently absorb regenerated electrical energy, stabilize the bus voltage, and prevent overvoltage tripping and component damage.
