China High Quality Customized Load Bank Manufacturer

Manufactured by Ruisite Electric,this 30kW max DC Load Bank Tester adopts nickel-chromium alloy resistance tube + forced air cooling, supporting continuous long-hour operation, with local touchscreen control and Modbus-RTU remote communication, built-in multi-layer safety protection to eliminate overload & overheat risks during long-duration testing.

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.

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 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.

RST Electric presents a compact and powerful 200kw Resistive Load Bank engineered for accurate AC power system validation.As global demand for reliable power infrastructure grows, medium-scale testing—whether for generator set commissioning, UPS system verification, or industrial power supply evaluation—requires consistent, high-resolution resistive loading.This 200kW AC Resistive Load Bank delivers fast load response (minimum step: 1kW), comprehensive safety protections (short circuit, over-voltage, over-temperature), and dual control modes (local HMI + remote PC/Modbus).Built with a rugged chassis and forced-air cooling system, it ensures reliable performance in continuous-duty applications for data centers, solar farms, and industrial plants.Contact RST Electric today for custom configurations including IP-rated enclosures, advanced metering options, or custom control software.
