48V to 24V 3A to 85A Step Down DC/DC Converter IP68 Waterproof Power Supply For Solar System

This highly efficient switch-mode step-down DC/DC converter is meticulously designed to convert a nominal input voltage of 48 VDC (accommodating a wide operating range from 30 VDC to 60 VDC) into a highly regulated and stable output voltage of 24 VDC. Engineered specifically as a non-isolated power supply (meaning there is no galvanic isolation between the input and output), these converters are perfectly suited for negative ground systems. Non-isolated converters typically offer a more compact footprint and superior energy transfer rates compared to isolated alternatives, providing a highly cost-effective yet powerful solution for applications where strict isolation is not required.

For procurement professionals and system integrators, selecting a reliable power conversion unit is critical for overall system stability. Our 48V to 24V series ensures consistent power delivery, minimizing equipment downtime and reducing long-term maintenance costs in demanding operational environments.

Core Features & Technical Advantages

• Exceptional Efficiency: Achieves an impressive conversion efficiency of up to 98% (tested at 48V input). This minimizes energy loss and significantly reduces thermal output, which is crucial for enclosed installations or poorly ventilated environments.

• Premium Internal Components: Equipped with high-reliability NCC and NICHICON internal capacitors. These industry-leading components significantly extend the operational lifespan of the converter and ensure stable performance under continuous, heavy loads.

• IP68 Waterproof Rating: Fully sealed and encapsulated to meet stringent IP68 waterproof standards. This provides ultimate protection against water ingress, dust accumulation, and heavy vibrations, making the unit highly dependable for outdoor and harsh industrial applications.

• Comprehensive Protection Mechanisms: Integrated with intelligent safeguards including short-circuit, over-load, over-temperature, overcurrent, and overvoltage protections. These features protect both the converter itself and the connected downstream equipment from unexpected electrical faults.

• Rigorous Quality Assurance: Every single unit undergoes a 100% full-load burn-in test prior to shipment, ensuring that only defect-free products reach your facility. Furthermore, the design fully complies with ROHS and CE certification standards, meeting strict international safety and environmental requirements.

Typical Applications & Use Cases

This versatile 48V to 24V step-down power supply is engineered to support a wide array of heavy-duty and precision applications. It is widely utilized in Solar Power Systems, where it efficiently steps down voltage for 24V battery banks, controllers, or monitoring equipment. Additionally, it provides stable power for Telecommunications infrastructure, ensuring uninterrupted signal transmission.

In the automotive and material handling sectors, it serves as an ideal power solution for Electromotors, Logging Vehicles, and Forklifts, where robust construction and vibration resistance are paramount. By integrating this IP68 waterproof converter into your equipment, you can effectively mitigate the risks associated with power fluctuations and environmental damage, ensuring that critical operations run smoothly in any condition.
