Load Bank Rata Load Bank Manufacturer
Product Overview
- The Rata Load Bank (model S2000L) from Deyang Rata Technology is a mobile, industrial-grade resistive load bank designed for high-power generator and power-system testing.
- Key ratings: 2000 kW (PF=1), 690 Vac rated testing voltage, 50 Hz, 3-phase (Delta) connection.
- Rugged IP54 outdoor enclosure with ISO lifting points for site portability; rough dimensions ~4500 × 2438 × 2600 mm and weight ~8,000 kg.
Product Features
- Precise, flexible loading: 10 kW resolution with multiple selectable step sizes to create a wide range of load profiles.
- Robust cooling and power-handling: horizontal forced air cooling (~2200 CMM approx.), six fans (3 kW each), AC contactor load switching.
- Protection and safety: thermal emergency cut-out, airflow switch, fan overload protection, emergency stop, and ground lead.
- Construction and testing: strict material selection, epoxy and mica insulation boards, insulation tested to 1500 VAC, short-term voltage tolerance +5%, load element tolerance ≤ +2.5%.
- Control options: local manual push-button control, PLC + handheld controller, or remote PC control with patented Nexus-1 software. Accessories include waterproof framed rubbers and zinc-coated copper busbars.
Product Value
- Verifies generator and power-system performance reliably under realistic loading: full and partial-power tests, voltage and frequency stability checks, and overload capacity/duration verification.
- Reduces commissioning and maintenance risk by detecting performance issues before deployment, improving reliability and uptime for critical power installations.
- Supports regulatory acceptance testing and asset lifecycle validation for high-value power equipment.
Product Advantages
- High capacity (2 MW) with fine load-step resolution for accurate, repeatable tests of large generator sets.
- Multiple control modes including advanced remote PC control (Nexus-1) for automated testing and data collection.
- Strong safety and thermal protections plus tested insulation and tight load element tolerances for dependable operation.
- Rugged, outdoor-capable enclosure and standardized lifting points for straightforward field deployment.
- Backed by experienced engineering, strict QC, and responsive after-sales service from the manufacturer.
Application Scenarios
- Load and acceptance testing of generator sets on oil drilling platforms (explicit use case).
- Commissioning and routine maintenance of industrial and standby generators in power plants, manufacturing, mining, and utilities.
- Data center generator testing and resilience validation.
- Rental/test houses, contractor field-testing, and factory performance verification of large rotating machines and prime movers.
- On-site overload testing, commissioning sequences, and backup-power system validation for large infrastructure projects.
