Rata Load Bank Load Bank Wholesale - Rata-8
Product Overview
- Model: R400 kW / 400 V / 50 Hz resistive load bank by Rata. Designed as a low-voltage, pure resistive load bank (power factor 1.0) for on-board and field generator testing. Outdoor-capable canopy (IP54), compact footprint (1150 × 1400 × 1600 mm) and approximately 550 kg weight with forklift holes for movement.
Product Features
- Rated power: 400 kW resistive only; voltage: 400 VAC, 3-phase 4-wire.
- Precise stepped loading: 1 kW + 2 kW + 2 kW + 5 kW + 10 kW + 10 kW + 20 kW + 50 kW + 3×100 kW (fine resolution including 1 kW step).
- Resistors: 8020 Ni-Cr alloy finned elements; forced-air cooling with horizontal discharge.
- Control: local panel plus remote PC control via Siemens PLC, RJ45 communication, load data save and printing. Panel includes phase-sequence indicator, instruments, step indicators, fan switch, alarms (high temp, low air volume), load switches and emergency stop.
Product Value
- Enables accurate, repeatable loading for commissioning, acceptance testing, preventive maintenance and diagnostics of diesel generators and other low-voltage power sources.
- Unity power factor and fine step resolution allow precise simulation of load profiles and staged loading for safe, controlled testing.
- Data logging and remote control support traceable test records and easier reporting for customers and regulators.
Product Advantages
- Built to standards with CE and ISO9001/14001/45001 certifications and international testing recognition.
- Robust outdoor design and high-quality Ni-Cr resistors for long service life; safety features and alarms for protected operation.
- OEM/ODM availability, 18 patents and experienced R&D/technical team (company operating since 2013, 7×24 support), enabling customization and reliable after-sales support.
- Packaged for transport (wooden case/pallet) and engineered for site handling.
Application Scenarios
- On-board/marine generator load testing and commissioning.
- Field and factory acceptance testing (FAT) of diesel generators and standby power systems.
- Routine maintenance and preventive load testing in utilities, rental fleets, industrial sites, data centers and power plants.
- Training, performance validation and diagnostic load runs where controlled resistive loading and documented results are required.
