Rata Dummy Load Bank Supplier
Product Overview
- 500 kW AC resistive dummy load bank for generator load testing and commissioning.
- Designed for outdoor use (IP54), three-phase 415 VAC, 4-wire connection; overall size ~1805 × 1560 × 1600 mm and weight ~950 kg.
- Dual control modes: local panel switching and remote PC control, with capability to save and print load test data.
Product Features
- Rated power: 500 kW (resistive only). Control voltage: 380 VAC, 3-phase, 4-wire.
- Flexible load stepping: continuously variable 0–10 kW plus discrete steps (e.g., 10 kW, 20 kW, 50 kW and multiple 100 kW steps).
- Resistive elements: 80/20 Ni–Cr alloy finned resistors for stable dissipation.
- Cooling: forced air cooling with horizontal air discharge.
- Protections: high temperature, low air volume, short circuit, over-current, phase sequence, and emergency stop.
Product Value
- Provides accurate, repeatable loading for generator capacity tests, performance verification and preventive maintenance.
- Enables on-site and remote testing with data logging/printing, improving test traceability and diagnostics.
- Outdoor-rated design and robust resistors allow reliable use in varied climates and industrial environments, reducing downtime and commissioning time.
Product Advantages
- Built by an experienced manufacturer (Rata) with 11 years in load bank design and production and exports to many countries.
- High-quality materials sourced from reliable suppliers and strict quality control to minimize defects.
- Fast delivery and established sales/service network, supported by R&D and continuous quality improvement.
- Comprehensive protection features and multiple control options for safe, flexible operation.
Application Scenarios
- Generator testing and commissioning (power plants, backup generators, rental gensets).
- Routine maintenance and load acceptance testing for industrial facilities, data centers, hospitals and commercial buildings.
- Factory testing of alternators, UPS systems and power electronics.
- Marine/shipboard testing and on-site temporary load applications where outdoor-capable equipment is needed.
