Guangdong Ruisite Electric Co., LTD. specializes in the design and manufacture of high-power AC and DC load banks for generator testing, power supply validation, and industrial electrical testing.Our Generator Load Banks are used across telecommunications, power utilities, data centers, manufacturing facilities, marine applications, and R&D laboratories.

RST Electric is a specialized manufacturer of 120kW 200V portable AC load banks in China. We utilize chromium-aluminum resistance wires and Schneider Electric control components, featuring five-stage graduated loading. Equipped with a quadruple protection system—including safeguards against over-temperature and over-voltage—our units are ideally suited for testing power supplies in military, marine, and aviation applications. They can be operated as standalone units or connected in parallel to expand capacity.

RST Electric is a manufacturer and supplier of the professional Aluminum Housing Resistor in China. China factory RXLG aluminum housed braking resistor 60W~2000W, 0.1Ω-10KΩ wirewound dynamic braking resistor, CE RoHS certified, IP20/IP54/IP65 optional for VFD, elevator, crane, servo, UPS & renewable energy load dissipation.

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.

RST Electric presents the RLC Load Bank – a precision power testing solution designed for applications requiring realistic simulation of complex electrical loads. Integrating resistive (R), inductive (L), and capacitive (C) elements in a single unit, this RLC Load Bank enables accurate emulation of power factors from 0.65 to 1.0, making it ideal for testing inverters, UPS systems, AC power sources, and renewable energy equipment. With three-phase independent adjustment, 0.1kW/0.1kvar load stepping, and ±3% loading accuracy, it delivers exceptional flexibility for R&D laboratories, quality assurance, and production testing.
