Product Overview
- Rata’s containerized resistive-reactive load bank is an outdoor-ready power testing solution offered at competitive pricing.
- Example configurations include model X5000L (apparent 5000 kVA / active 4000 kW at 400 VAC) and higher-capacity, custom units (customer designs can reach much larger kVA ratings).
- Designed to simulate real-world loads at a variety of power factors (standard PF 0.8 for combined resistive/reactive testing), it is built in a weatherproof ISO-style container for portability and field use.
- Manufactured under Rata’s ISO9001-based quality system with extensive factory acceptance testing.
Product Features
- Combined resistive and reactive load elements with fine step resolution (e.g., 100 kW active steps and 10 kVar reactive steps) and robust load-element tolerance (≤ +2.5%).
- Air-forced cooling with high airflow, horizontal intake and vertical exhaust; multiple high-power fans and thermal protections for continuous outdoor operation.
- Rugged containerized carbon-steel enclosure with marine-grade painting, IP54 control chamber, standard ISO lifting points, and rated operation from −20 °C to +60 °C (altitude configurable).
- Comprehensive protection and control: thermal emergency cutoff, fan overload, airflow switches, emergency stop, 3-pole AC contactor switching, copper busbar connections, and multiple control options (local, PLC/remote, cloud).
- Customizable parameters: voltage, power capacity, cooling direction, control power source, and power factor to match customer requirements.
Product Value
- Enables realistic, repeatable load simulation for reliable commissioning, verification and preventative maintenance of generators, UPS, switchgear and power distribution systems.
- Reduces the risk of failures and downtime by allowing full-capacity loading and diagnostics off-line, improving asset life and operational confidence.
- Custom design capability lets customers get right-sized, cost-effective solutions rather than overpaying for unsuitable equipment.
- Onsite commissioning, testing support and operator training help accelerate deployment and ensure correct use.
Product Advantages
- Proven quality control with ISO9001-based processes and thorough FAT (many checking points) before shipment.
- High ruggedness and portability (containerized build, ISO lifting points, outdoor IP54-rated control room) for demanding field environments.
- Flexible customization and wide power range (from small kW modules to multi-MW systems) to fit diverse customer needs.
- Strong safety and protection features plus multiple control integration options (local/remote/SCADA/cloud).
- Experienced R&D, production and service teams providing technical support, onsite testing, and long-term collaboration.
Application Scenarios
- Generator and prime mover full-load testing and commissioning (power plants, rental gensets, municipal and industrial installations).
- UPS, battery and energy-storage system verification and maintenance for data centers and critical facilities.
- Load bank testing for switchgear, transformers, and protective devices in utilities and industrial sites.
- Factory acceptance testing, system commissioning, and contractor site validation.
- Portable rental fleets for outage support, emergency services, and field service providers.
