Deyang Rata Launches SIRL-250L AC Resistive-Inductive Load Bank for Advanced Power System Testing
DEYANG, China - July 23, 2026 - Deyang Rata Technology Co., Ltd., as a resistive inductive load bank manufacturer [https://www.cnloadbank.com/load-bank/inductive-load-bank/] and a developer of power testing solutions, has announced the launch of the SIRL-250L Series 250kVA AC Resistive-Inductive Load Bank, expanding its portfolio of testing equipment for industries requiring precise electrical performance verification. The introduction reflects growing demand for advanced testing technologies as utilities, industrial facilities, data centers, and energy storage projects place greater emphasis on power system reliability and operational readiness.
The SIRL-250L has been developed to provide comprehensive resistive and inductive load simulation for a wide range of electrical systems. By enabling engineers and operators to accurately replicate real-world operating conditions, the load bank supports equipment commissioning, preventive maintenance, and performance validation across critical infrastructure projects.

As investments continue in renewable energy, battery storage, digital infrastructure, and standby power systems, organizations are placing greater importance on validating equipment performance before assets enter service. Generator sets, UPS systems, distribution networks, and Battery Energy Storage Systems (BESS) all require dependable testing to help verify operational performance under varying electrical loads.
The SIRL-250L was designed to address these evolving requirements by combining resistive and inductive load simulation within a single testing platform. This capability allows operators to evaluate both active and reactive power characteristics, providing a more comprehensive assessment of electrical equipment during testing procedures.
The solution is intended for engineering contractors, power utilities, equipment manufacturers, maintenance providers, and facility operators seeking greater precision during commissioning and routine maintenance activities.
Enhanced Load Resolution Improves Testing Accuracy
A distinguishing feature of the SIRL-250L is the inclusion of 0.5kW and 0.5kVar fine load steps, providing enhanced adjustment resolution for both active and reactive power. These smaller increments enable testing personnel to match target kW and kVar values with greater precision during field operations.
The system supports 400Vac, 50Hz, three-phase, four-wire testing, while the auxiliary power supply also operates at 400Vac, 50Hz, simplifying deployment within industrial environments using standard electrical infrastructure.
The finer load adjustment capability is particularly valuable for applications requiring detailed performance verification, allowing engineers to conduct more accurate system evaluations without relying on larger load increments.
Intelligent Control Supports Modern Testing Operations
The SIRL-250L incorporates an intelligent control system designed to improve operational flexibility during testing. Users can operate the load bank through either local controls or remote interfaces, allowing testing activities to be managed according to project requirements and site conditions.
The system also integrates the 8961 F2 data acquisition and generator testing function, enabling comprehensive monitoring throughout the testing process. This functionality provides operators with detailed performance information while supporting generator testing procedures that require accurate data collection.
By combining intelligent controls with integrated monitoring capabilities, the load bank helps simplify testing workflows while supporting efficient operation across a variety of industrial environments.
Safety Features Designed for Industrial Reliability
Safety remains a primary consideration in the design of the SIRL-250L. The unit incorporates a hardwired safety protection circuit intended to support dependable operation throughout demanding testing applications.
The protection system includes fan fault protection, low airflow protection, over-temperature protection, and emergency stop functionality. These features are designed to enhance equipment protection while helping maintain stable operating conditions during extended testing periods.
The compact industrial design also supports installation in locations where available space may be limited without compromising operational capability or cooling performance.
Applications Across Multiple Industries
The SIRL-250L has been developed to serve a broad range of industries that depend on accurate electrical testing. Typical applications include generator set load testing, UPS verification, on-load validation of electrical grid and distribution systems, server load simulation for data centers, and Battery Energy Storage System testing.
The combination of resistive and inductive load simulation allows organizations to evaluate power systems under operating conditions that closely resemble real-world electrical demand. This capability supports improved commissioning processes, maintenance planning, and equipment verification across mission-critical facilities.
Deyang Rata also identifies Algeria as one of the target markets for the new solution, reflecting continued infrastructure development and increasing investment in reliable electrical power systems throughout the region.
Quality Manufacturing Process
Production of the SIRL-250L follows a structured manufacturing process beginning with material selection and component preparation. Engineers then complete load module fabrication, control unit assembly, cooling system integration, circuit wiring, and enclosure assembly before each unit proceeds to commissioning.
Every load bank undergoes functional testing, quality inspection, and performance verification under demanding operating conditions to help ensure consistent product reliability before shipment.
