4KW 54V DC Adjustable Resistive Load Bank For UPS Battery Power Supply Testing

The JH-RYF-4KWD54-W6K-JJ represents the gold standard in industrial-grade rack-mounted load bank solutions, designed for mission-critical power testing applications. As a rack-mounted load bank, it delivers 4kW of precision DC loading capacity within a compact 19-inch chassis (485×450×177mm), making it ideal for data centers, marine power systems, and telecom installations where space optimization is crucial.

This rack-mounted load bank features six manually-switched power stages (400W×2 + 800W×4) with ±5% current accuracy, allowing engineers to simulate real-world load conditions from 400W to 4kW. The rack-mounted load bank's ultra-thin resistor array maintains <350℃ surface temperature at full load, supported by IP20-rated enclosure with <35℃ external temperature rise - a testament to its superior thermal management as a rack-mounted load bank.

Precise Load Simulation: The JH-RYF-4KWD54-W6K is designed to simulate various load conditions encountered by uninterruptible power supplies (UPS). It allows accurate testing and validation of UPS systems.

Adjustable Load Levels: With its adjustable load capacity ranging from 1KW to 4KW, this load bank accommodates different load scenarios. Engineers can fine-tune the load to match specific UPS requirements.

Real-time Monitoring: Equipped with a display panel, it provides real-time monitoring of load current, voltage, and frequency. This feature aids in assessing UPS performance during testing.

Stability and Safety: By applying controlled loads, the JH-RYF-4KWD54-W6K ensures stable UPS operation and prevents voltage fluctuations. It contributes to system reliability.

Compact and Portable: Its compact form factor allows easy integration into testing setups. Additionally, the load bank’s portability facilitates on-site testing and maintenance.

As a rack-mounted load bank, it serves vital roles in:

1. Generator performance validation (marine/aviation)

2. Data center UPS load testing

3. Renewable energy storage evaluation
