Rata Load Bank by Rata-28

Product Overview

- The Rata three‑phase load bank is a configurable AC test system combining resistive, inductive and capacitive loads with independent control per phase.

- It can precisely simulate arbitrary load conditions and AC resonance (including Q=1 resonance where inductive = capacitive = resistive currents), even when supply voltages are unbalanced.

- Available in low- and medium‑voltage models across a wide power range (hundreds of kW to multi‑MW), with parallel expansion of multiple load containers and customization to customer needs.

Product Features

- Independent three‑phase power control and sectional (step) combined control to emulate varied load profiles; minimum step 1 kW.

- Accurate resonance adjustment and fast phase‑by‑phase debugging for unbalanced voltages; essential for testing anti‑islanding protection of grid‑connected inverters.

- Loading accuracy ≤3%, three‑phase unbalance ≤3%, measurement/display accuracy (display 0.5, sampling 0.2).

- Robust protections: short circuit, overcurrent, overtemperature, fan fault; forced air cooling; insulation class F.

- Practical design for transport/installation: lifting holes and rollers, customizable color/size, supports ship/military/telecom standards.

Product Value

- Enables reliable, repeatable full‑load testing and commissioning of inverters, generators and power systems—reducing field failures and ensuring compliance.

- Accurately simulates resonance and anti‑islanding conditions, improving safety and verification of PV grid‑tied equipment.

- Scalable and customizable across voltage/power ranges, delivering cost‑effective testing for production lines, labs and on‑site commissioning.

- Speeds R&D, quality control and maintenance work by providing a single multifunction test platform.

Product Advantages

- Manufactured to international standards with strict quality control and proven factory R&D capability; company holds multiple patents and software copyrights.

- Wide power and voltage options (low to medium voltage), high configurability and parallel expandability to meet diverse customer requirements.

- Competitive pricing with full customization, experienced after‑sales support and shipping/packaging suitable for long‑distance transport.

- Comprehensive electrical/thermal protections and accurate instrumentation make it a reliable, durable test solution.

Application Scenarios

- Production workshops and factory acceptance testing for generators, inverters and power equipment.

- Laboratory testing, R&D and performance validation of photovoltaic grid‑connected inverters (anti‑islanding and resonance tests).

- Installation, on‑site commissioning and maintenance at power plants, shipyards, telecom sites and industrial facilities.

- Load leasing, system troubleshooting, preventive maintenance and qualification tests for military or shipboard power systems.
