Product Overview
1) Product overview
Product Features
- Rata resistive load bank (example model: R2500kW marine load bank) is a containerized, low/medium-voltage test load system designed for continuous, high‑capacity power testing. It supports resistive and inductive loading, star–delta voltage conversion (AC 400V ↔ 690V) and transformer-based voltage stepping (400V up to ~10kV). Units are modular and can be paralleled for higher total capacity, and are built for outdoor transportable use.

Product Advantages
- Containerized outdoor construction with integrated resistive elements, inductors, electrical control, data acquisition, heat dissipation and protections.
Application Scenarios
- Scalable power range and modular parallel expansion (typical models span from ~100 kW to multi‑MW assemblies; capacity and dimensions are customizable).
- Fine load resolution (minimum step 1 kW / 1 kvar; step increments customizable), loading accuracy ±3% and three‑phase imbalance ≤3%.
- Star–delta connection to cover AC400V (delta) and AC690V (star) operation; transformer option for medium voltage rise.
- Forced air cooling (side or top outlet), continuous duty rating, instrument sampling accuracy class 0.2 (voltage ±0.5%, current ±0.5%, frequency ±0.1%, power ±1%, power factor ±1%).
- Robust protections: short circuit, over‑voltage, over‑current, over‑temperature, low air volume and emergency stop.
- Resistant components: special alloy resistors with high insulation and stability; aluminum or copper reactors for inductive loads; protection rating IP56 (idle) / IP20 (in use).
3) Product value
- Provides accurate, repeatable and safe load testing for generators, switchgear, UPS, transformers and power systems, enabling reliable commissioning, acceptance testing, maintenance and capacity verification.
- Modular and customizable design reduces project risk and lead time by matching site voltage/frequency/size requirements.
- High measurement accuracy and comprehensive protections improve test confidence, reduce downtime and protect expensive equipment from mis‑testing.
- Built to industry, marine, military and telecom standards so results are acceptable for formal acceptance and certification processes.
4) Product advantages
- High build quality using premium raw materials and rigorous testing; proven long durability and operational stability praised by customers.
- Flexible voltage handling via star–delta conversion and transformer options for both low and medium voltage applications.
- Precise load control (1 kW steps), good three‑phase balance and reliable instrument accuracy for exact load simulation.
- Strong safety suite and environmental ruggedness for outdoor and transportable use; customizable cooling and enclosure features.
- Backed by Rata’s technical experience, IP (patents) and international export track record, plus first‑class customer support.
5) Application scenarios
- Marine and shipboard testing and commissioning (marine load bank variant).
- Power plant, generator set and large UPS acceptance and routine load testing.
- Medium/low voltage switchgear, transformer commissioning and system stability tests.
- Telecommunications, military and industrial sites requiring certified load verification.
- Factory production testing for power equipment manufacturers, maintenance contracts, and on‑site emergency power system validation.
