7KW Adjustable DC Load Bank with Dual Voltage Conversion for Battery and Power Supply Testing

The JH-RYF-7KWD30D15-W8K is a DC resistive load bank designed for professional power system testing, verification and load simulation. Built by Githai, the 7KW device supports dual voltage compatibility (DC30V/DC15V switchable), making it ideal for testing batteries, DC power supplies, solar systems, and small energy storage devices.

Designed for 24/7 continuous operation, this load bank combines safety, accuracy, and ease of use to ensure you can verify power performance and detect hidden faults.

• Flexible 8-Step Load Adjustment: With 8 independent power levels, you can simulate loads from 100W up to 7KW, enabling incremental testing to match your exact requirements. The modular circuit breaker design lets you combine stages for precise load tuning.
• Safety & Protection System: Safety is built into every component: Emergency stop button for immediate load cut-off, overheat alarm and thermal protection to prevent overheating, overvoltage protection safeguards both the load bank and test equipment.
• Continuous 24/7 Operation Capability: Engineered for long-duration testing, the forced air cooling system maintains stable operating temperatures even under full 7KW load. The industrial-grade fans ensure efficient heat dissipation, supporting 7*24 hour continuous use for factory burn-in tests, performance validation, and endurance testing.
• User-Friendly Operation: The intuitive control panel features a digital display showing real-time voltage, current, and power readings, so you can monitor test conditions at a glance. No complex programming is required—simply select your desired load stages via the circuit breakers and start testing immediately.

1. Battery and Energy Storage System Testing: Verify the capacity, discharge performance, and operating time of batteries and small energy storage systems at 15V/30V voltages.
2. DC Power Supply Verification: Test the output stability, efficiency, and overload protection of laboratory power supplies and industrial DC adapters.
3. Solar Panels and Photovoltaic System Testing: Simulate actual loads to evaluate the output of solar panels and the performance of small off-grid solar systems.
4. Generator and Standby Power Supply Testing: Verify the performance of low-voltage DC generators and standby power supply devices under controlled load conditions.
5. Electronic Manufacturing: Conduct aging tests and quality control checks on DC power supply equipment on the production line.
