Resistive Load Banks Rata Load Bank Company
Product Overview
- Model: RT500KWLB — a 500 kW resistive load bank designed to test and evaluate power supply equipment such as generators, UPS systems and other electrical equipment.
- Canopy design for both indoor and outdoor use, 3-phase 4-wire construction with customizable rated voltages (AC 380V, 400V, 415V, 440V, 690V or customer-specified).
- Continuous-duty device with local panel switching and remote PC control (Modbus TCP/PLC compatible) for flexible operation and data logging.
Product Features
- Precise loading: 1 kW resolution steps (composite steps include 1kW, 2kW, 2kW, 5kW, 10kW, 10kW, 20kW, 50kW, 4×100kW) and loading accuracy ≤ 3%; 3-phase unbalance ≤ 3%.
- Resistive elements: 8020 Ni–Cr alloy finned resistors; forced axial air cooling with horizontal intake/outlet; noise < 80 dB at 3 m.
- Protection and instrumentation: high-temperature, low-air-volume, phase-sequence, short-circuit, fan interlock and emergency-stop protections plus digital meters for voltage, current, power, power factor and frequency.
- Expandability and logistics: supports parallel expansion of multiple units; forklift holes or universal wheels for movement; enclosure Q235 steel, powder-coated (RAL 7035).
Product Value
- Provides a reliable, accurate, and safe means to perform full-load, partial-load and endurance testing of generators, UPS systems and other power equipment — reducing commissioning time and operational risk.
- Remote-control and data logging capabilities enable reproducible test sequences, record keeping and easier compliance with international, ship, military and telecom test standards.
- Robust canopy design and protective features make it suitable for harsh environments and extended field use, minimizing downtime and test-related failures.
Product Advantages
- High build quality and industrial design (Ni–Cr resistors, Q235 enclosure, proven cooling and protection systems) for dependable continuous operation.
- Flexible control options (local manual panel or remote PC with Modbus TCP/PLC and printing/data-save support) for OEM, field and lab workflows.
- Scalable: clear provision for parallel expansion to meet larger load requirements; voltage customization for diverse markets.
- Backed by a manufacturer focused on R&D, quality management and broad industry experience, with established domestic and international customer base.
Application Scenarios
- Generator and prime mover commissioning, acceptance testing and routine maintenance.
- UPS and battery bank testing for data centers, hospitals and critical facilities.
- Telecom and military power system verification and environmental/shipboard testing.
- Factory acceptance tests, production line QA for power equipment manufacturers and rental/servicing companies providing on-site load testing.
