Deyang Rata launches 4MW RLC load bank for power testing

Deyang Rata Technology Co., Ltd. has introduced a 4MW RLC combined load bank in Deyang, China, to test generators, energy storage systems and industrial power equipment. The containerized system combines resistive, inductive and capacitive loading in one platform, aiming to support commissioning, acceptance testing and performance verification across power projects.

Why it matters: - The 4MW RLC Combined Load Bank gives power operators one system for testing resistive, inductive and capacitive loads. - The platform is built to support commissioning and acceptance testing for generators, energy storage systems and industrial power equipment. - The product targets projects where engineers need to simulate real operating conditions before equipment enters service.

What happened: - Deyang Rata Technology Co., Ltd. launched the Rata 4MW RLC Combined Load Bank in July 2026 in Deyang, China. - The containerized load bank is designed for testing, commissioning and performance verification across a wide range of power system applications. - The launch expands Deyang Rata Technology's portfolio of professional power supply testing solutions.

The details: - The load bank supports steady-state testing, regulation testing, fluctuation testing, sudden load-on testing, sudden load-off testing, harmonic analysis and waveform recording analysis. - The system supports one-click load increase and decrease operations. - The equipment is designed for gas turbine generators, diesel generators, energy storage converters, UPS systems, gas-fired power plants, offshore platform power systems, factory acceptance testing and domestic and international EPC commissioning projects. - The combined resistive, inductive and capacitive design supports continuously adjustable power factors from 0.8 lagging through unity to 0.8 leading. - The rated resistive load capacity is 4,000 kW. - The system supports both 480V low-voltage and 13.8kV high-voltage systems. - The resistive, inductive and capacitive loads can be adjusted independently. - The inductive load is verified at 60 Hz with a 0.8 power factor. - The capacitive load is verified at 50 Hz with a 0.9 power factor. - The load bank delivers 5% step accuracy and 3% overall loading accuracy. - The minimum resolution is 1 kW for resistive loads and 1 kVar for inductive and capacitive loads. - Local touchscreen control and remote PC operation are available through a PLC-based control system with RJ45 Ethernet connectivity. - The software supports steady-state, transient, manual, preset, automatic, step, constant-power and power compensation loading modes. - The software also provides real-time parameter monitoring, safety monitoring, adjustable data acquisition intervals, graphical curve display, data storage and retrieval, steady-state data comparison and test report export functions.

Between the lines: - The feature set points to a product built for field testing as well as laboratory use, not just fixed-site commissioning. - The combination of adjustable reactive loads and multiple loading modes gives engineers more control over how generator and power system behavior is simulated. - The design aligns with Chinese national standards and IEEE testing requirements, which may help the system fit into both domestic and international project workflows.

What's next: - Deyang Rata Technology says the platform will be used for performance verification during equipment commissioning and acceptance testing. - The company also offers customization of system parameters and operational functions based on project requirements. - Customers receive Chinese and English technical documentation, factory test reports, on-site commissioning support and warranty services for domestic and international installations. - The load bank is intended for factories, power plants, overseas project sites, offshore platforms and other industrial environments requiring mobile testing equipment.

The bottom line: - Deyang Rata is pitching the 4MW RLC Combined Load Bank as a single mobile platform for broad, high-capacity power system testing across industrial and utility applications.
