Product Overview


Our 24V to 13.8V DC DC Step Down Buck Converter is an industrial-grade, non-isolated switch-mode power solution designed to deliver exceptional reliability for demanding power environments. Engineered to convert a nominal 24V DC input—accommodating a wide 18-36VDC fluctuation range—into a strictly regulated 13.8VDC stable output, this unit ensures your sensitive electronics receive consistent power. Specifically configured for negative ground systems, the series provides a versatile output current range from 5A up to 100A, translating to a rated power capacity of 69W to 1380W to meet diverse industrial and commercial power demands. With an industry-leading conversion efficiency of up to 96.8%, this 18-36VDC to 13.8VDC DC Power Converter significantly minimizes energy loss and thermal dissipation. It serves as the ideal power conversion solution for heavy-duty mobile equipment, fixed industrial automation, and harsh operational environments where consistent performance is critical for procurement and engineering teams.

Core Advantages for System Integration & Procurement


Ultra-High Efficiency for Reduced Operating Costs

Our 24V 13.8V Buck Converter delivers up to 96.8% peak efficiency, drastically cutting energy waste and thermal generation during long-term operation. This superior thermal management translates to lower power consumption, extended internal component service life, and reduced maintenance costs, creating tangible long-term value for bulk deployment projects and equipment manufacturers.

IP68 Waterproof & Rugged Design for Harsh Environments

Encased in a rugged aluminum shell with full epoxy potting, this converter achieves an IP68 waterproof and dustproof rating. It is fully sealed against water immersion, heavy dust, and severe mechanical vibration, making it highly reliable for outdoor applications and heavy-duty mobile equipment. It withstands extreme working conditions without performance degradation, effectively eliminating frequent replacement costs.

Comprehensive Protection for Uninterrupted Operation

To safeguard your critical systems, the converter features built-in automated protections against short circuits, overloads, over-temperature, and over-voltage scenarios. The intelligent circuit design ensures a stable power supply even during abnormal conditions, automatically recovering once the fault is removed. Every unit undergoes strict 100% full-load burn-in testing before delivery.

Flexible Specifications for Custom Project Needs

We offer 11 standard current ratings ranging from 5A to 100A, providing seamless scalability for projects of any size. Additionally, we support custom voltage, current, and housing configurations for bulk orders. This flexibility allows system integrator partners to find the exact fit for unique project requirements without incurring excessive customization fees.


Target Industries & Applications


This IP68 Waterproof DC DC Converter for Forklifts is widely deployed across industries demanding reliable, rugged power conversion. Typical applications include material handling equipment (powering 12V/13.8V accessories on 24V forklifts, pallet trucks, and logging vehicles), industrial automation (electromotor control, conveyor systems), telecommunications (remote base stations, backup power networks), and marine/outdoor mobile equipment (RVs, utility vehicles, and outdoor monitoring devices). Its robust design ensures it meets the strict operational standards of these demanding sectors.
