Product Overview
- Model RT500KWLB is a 500 kW resistive canopy load bank designed to test and evaluate generators, UPS systems, power supplies and other electrical equipment.
- Can be used indoors or outdoors (canopy design), supports 3-phase 4-wire systems and is available for common industrial voltages (AC 380V, 400V, 415V, 440V, 690V or customized).
- Continuous-duty device with local panel switching and optional remote PC control (Modbus TCP/PLC with logging and printing).
Product Features
- Rated 500 kW resistive loading with ≤3% loading accuracy and ≤3% 3-phase unbalance.
- Fine control: 1 kW resolution and multiple load step sizes (1kW, 1kW+2kW+2kW+5kW+10kW+10kW+20kW+50kW+100kW×4).
- Resistive elements: 8020 Ni-Cr alloy finned resistors; cooling by forced horizontal airflow with axial fans (noise
- Protection and monitoring: high-temperature, low air volume, phase sequence, short-circuit, fan interlock, emergency stop; digital meters for voltage, current, power, power factor and frequency.
- Expandable (parallel expansion of multiple units), portable via fork lift shoes / universal wheels, rugged Q235 powder-coated enclosure.
Product Value
- Provides accurate, repeatable, full-load simulation for commissioning, performance verification, preventive maintenance and failure diagnosis of power systems.
- Reduces risk of unplanned outages by validating generator/UPS performance under realistic loads and supporting routine load bank testing schedules.
- Data logging and remote control enable traceable test records and streamlined reporting for compliance and quality assurance.
Product Advantages
- Industrial-grade design meeting ship, military and telecommunication standards; manufactured under strict QC procedures.
- Flexible control: choose local manual switching or automated remote PC/PLC operation with Modbus TCP and data saving/printing.
- Robust components and protections for safe continuous operation across a wide ambient range (-20°C to 50°C, up to 2500 m altitude and 100% humidity).
- Scalable and customizable (voltages, step configurations) to match diverse customer requirements; cost-effective with long service life.
Application Scenarios
- Commissioning and routine load testing of diesel/gas generator sets and prime movers.
- UPS, switchgear and power distribution acceptance testing in data centers, hospitals and industrial plants.
- Telecom sites, military and marine installations requiring hardened, standards-compliant load testing.
- Factory maintenance shops, rental fleets, research & development labs and any facility needing controlled resistive load simulation.
