RST Electric introduces a heavy-duty 400kW 400V Load Bank engineered for large-scale AC power system validation. Designed for utility-scale generator testing, mission-critical UPS commissioning, and industrial power applications, this 400kW 400V AC Load Bank delivers high-precision resistive loading with advanced step control and comprehensive safety protections. Built for continuous full-load operation, it features forced air cooling, a rugged IP20-rated chassis, and dual-control modes4 including local HMI and remote PC/Modbus interface. Whether deployed in power plants, hyperscale data centers, or renewable energy facilities, this load bank provides the reliability and accuracy required for demanding test environments.
1.Heavy-Duty Engineering – Designed for continuous operation at full rated power, ideal for long-duration burn-in and reliability testing.
2.Smart Thermal Management – Variable-speed fans with temperature sensors optimize cooling efficiency while minimizing noise.
3.Industrial-Grade Safety – Multi-layer protection includes emergency stop, phase loss detection, and independent overtemperature cutoff.
4.Advanced Connectivity – Standard Modbus-RTU/RS485 interface enables SCADA integration; optional Ethernet/IP for Industry 4.0 applications.
5.User-Centric Design – Large HMI display with intuitive menu navigation; one-touch load presets for repeatable test sequences.
6.Future-Ready Scalability – Master-slave parallel operation allows combining multiple units for multi-megawatt testing capacity.
● Utility Power Plants – Essential for commissioning and periodic testing of gas turbines, diesel generators, and steam turbines.
● Hyperscale Data Centers – Validates UPS systems, backup generators, and power distribution units (PDUs) under full load conditions.
● Renewable Energy Integration – Tests utility-scale solar inverters, wind turbine converters, and battery energy storage systems (BESS).
● Industrial Manufacturing – Ensures reliability of large motors, variable frequency drives (VFDs), and plant power systems.
● Marine & Offshore – Suitable for shipboard generator testing and offshore platform power system validation.
● Research Laboratories – Provides precise load simulation for power electronics development and grid stability studies.
To ensure the safe transportation of the 400KW 400V Load Bank, RST Electric have developed a strict packaging process that guarantees the equipment will remain undamaged during transportation. Each load box is first wrapped with multiple layers of waterproof film to effectively isolate moisture, dust, and other external disturbances. Then, it is securely fixed with heavy-duty steel straps to prevent loosening or collision during transportation. At the same time, the equipment is installed on reinforced wooden skids, which facilitates forklift loading and unloading, thereby enhancing transportation efficiency. For international transportation, we use custom plywood crates for packaging and provide fumigation certificates, strictly complying with the ISPM 15 international standard, to ensure the smooth passage of goods through customs inspections in various countries. Additionally, we prepare all relevant transportation documents in advance, including packing lists, inspection reports, and customs clearance auxiliary materials, to fully ensure a smooth and unobstructed logistics process. We collaborate with industry-leading freight forwarders, who can provide flexible transportation solutions based on customer needs. Whether it's full container shipping, air freight, or urgent order delivery requiring express delivery, we can respond efficiently and ensure the equipment is delivered to the customer on time.
