Rata Ac Resistive Load Bank Manufacturer Manufacturer
Product Overview
- Rata 2500 kW marine load bank — containerized low-voltage/medium-voltage resistive‑/inductive load bank designed for heavy-duty generator and power-system testing.
- Configurations support AC 400 V–690 V via star‑delta conversion and voltage rise to 10 kV via a dry‑type transformer; medium‑voltage units are typically built in long (≈9.5 m) containers.
- Modular design allows parallel expansion of multiple load containers; continuous operation and customization of rating, steps and layout.
Product Features
- Combined resistive and inductive load capability with configurable power factor (example 0.8) and minimum resistive step 1 kW (inductive step 1 kvar).
- Accuracy and monitoring: instrument sampling class 0.2; Voltage ±0.5%, Current ±0.5%, Frequency ±0.1%, Power ±1%, PF ±1%; loading accuracy ±3%, three‑phase imbalance ≤3%.
- Protection and reliability: short‑circuit, over‑voltage, over‑current, over‑temperature, low air volume and emergency‑stop protection.
- Cooling/packaging: forced‑air cooling (side or top outlet), outdoor container type, transport lifting points; protection IP56 when stored, IP20 in service.
- Environmental ranges: -20 °C to 50 °C, up to 100% humidity, altitude ≤ 2,500 m. Many parameters fully customizable.
Product Value
- Provides accurate, repeatable, and safe simulation of real generator and grid loading for commissioning, acceptance testing, preventive maintenance and performance verification.
- Reduces downtime and commissioning risk by allowing full-load testing off-line from customer systems.
- Scalable and transportable solution that adapts to on‑site constraints and varying voltage/frequency requirements, saving time and cost versus bespoke test arrangements.
Product Advantages
- Mature, field‑proven design with emphasis on stability, durability and safety; praised by cooperative customers and suitable for ship/military/telecom standards.
- Wide voltage handling (400 V–10 kV via transformer) and star‑delta conversion for flexible deployment across multiple voltages.
- High customization capability (ratings, steps, protective features, enclosure, color, standards compliance).
- Backed by Rata’s IP, software copyrights and national high‑tech recognition; global export experience (USA, Europe, Asia, South America).
Application Scenarios
- Marine and shipboard power system testing and commissioning.
- Generator set acceptance, load bank testing for power plants and large backup generators.
- Telecom, data center and UPS system verification and maintenance.
- Industrial and manufacturing power equipment testing, military and shipyard test facilities.
- Any scenario requiring controlled resistive/inductive load simulation, performance tuning or reliability validation.
