High Quality Resistive Load Bank Testing Company
Product Overview
- Rata programmable resistive load bank (example model: Rata 800 kW / 400 V / 50 Hz) is a compact, transportable, PLC‑controlled load bank designed for accurate, continuous resistive loading. It integrates dry resistive elements, electrical control, and measurement/control systems in one container and supports parallel expansion of multiple load units. Units are built to international, ship, military and telecommunication standards and can be customized across a wide power range (low- and medium-voltage models available).
Product Features
- Built-in Siemens PLC logic controller with user‑programmable control logic.
- Configurable load steps and minimum step as low as 1 kW; loading accuracy ≤ 3%; three‑phase unbalance ≤ 3%.
- Dry resistance elements (high insulation, DC1000 V/100 MΩ+, AC 2000 V withstand for 5 min) — no liquid cooling required.
- Continuous working mode with forced air cooling (side or top outlet), insulation class F.
- Multiple control modes: local manual, local automatic, or remote automatic.
- Protection functions: short circuit, overcurrent, high temperature, fan fault.
- Measurement/display: three‑phase voltage, current, frequency, power with display accuracy ~0.5 and sampling accuracy ~0.2.
- Transport/mobility design: lifting holes and bottom rollers for easy handling.
- Fully customizable (size, color, functions, OEM nameplates).
Product Value
- Reliable, accurate and repeatable load testing for generators, UPS, power systems and electrical equipment — reduces commissioning and maintenance risk.
- Safer and cleaner than wet/water load systems (no leakage, no harmful gases or wastewater), lowering environmental and operational hazards.
- Time and cost savings via one‑stop supply from manufacturer (design, OEM, customization, technical drawings) and modular expansion to match changing test needs.
- Continuous, long‑term operation capability enables realistic endurance and performance testing without frequent interruptions or preparatory setup.
Product Advantages
- Industry‑leading technology and quality control from Deyang Rata Technology Co., LTD (multiple patents, software copyrights, national high‑tech recognition).
- Compact, portable design with high power density and easy parallel scaling.
- High safety and protection levels with robust electrical and thermal safeguards.
- Flexible configuration and strong OEM support — custom materials, sizes, and functions available; professional R&D and technical documentation provided.
- Competitive pricing, responsive service (24/7 support), and experience serving ship, military, telecom and industrial standards.
Application Scenarios
- Testing and commissioning of diesel and gas generator sets, automatic transfer switches and switchgear.
- Data centers and UPS system load testing and verification.
- Power plant commissioning, maintenance and performance verification.
- Telecommunications, naval/marine, and military equipment testing (meets ship and military standards).
- Factory acceptance testing, electrical lab test benches, and manufacturing quality control.
- Anywhere utility, industrial or commercial power supply equipment requires controlled, repeatable resistive loading for diagnostics, performance validation or endurance testing.
