Import 25-27a 13.8v Dc Regulated Power Supply — Buy in Bulk from Supplier in China

The 25-27A 13.8V DC Regulated Power Supply from Hokog Electronics Co., Ltd. is an industrial-grade unit built to deliver stable direct current for sensitive electronic loads. It provides a regulated output of 13.8 volts with a current capacity between 25 and 27 amperes, suitable for applications demanding consistent voltage under variable draw. Input compatibility covers both 230Vac and 117Vac at 50-60Hz, allowing deployment across regions with differing mains standards. Load regulation is rated at 10%, meaning output variation stays within this band as connected equipment cycles on and off.

The power supply employs switch-mode or linear regulation architecture (buyers should confirm topology with the supplier) to convert alternating mains to the specified 13.8V DC rail. A 30-minute continuous operation rating is stated, which suggests either thermal management limits or a duty-cycle design; confirm whether this applies at full 27A load or derated conditions. The 13.8V output is a standard float-charge voltage for 12V lead-acid battery systems, making this unit common in telecommunications backup and amateur radio power applications. Enclosure style, cooling method (fan or convection), and protection features (overvoltage, overcurrent, thermal cutout) are not detailed in the source and should be requested from Hokog Electronics directly.

Typical buyers include telecommunications infrastructure installers, industrial automation integrators, research laboratories, and amateur radio operators who require a clean, stable DC bus. The dual input voltage selector broadens deployability for OEMs shipping equipment globally. When engaging Hokog Electronics, confirm the continuous duty derating curve, ambient temperature range for rated output, and whether the 30-minute limit implies a thermal reset cycle or mandatory cooldown period. EMC compliance class (Class A or B), safety certifications (UL, CE, CCC), and modular connector options are additional specifications worth clarifying before bulk commitment.

Hokog Electronics Co., Ltd. is headquartered at No.238, Xueyuan Road, Haishu District, Ningbo, Zhejiang Province, China, placing it within the Ningbo port manufacturing corridor with access to Shanghai-Ningbo maritime logistics. The supplier is classified at imported tier with harbor trust tier, indicating a baseline level of platform data importation without additional verification badges. The response rate is recorded at 0.00% with zero average response hours, which signals that direct engagement through messaging channels may be unreliable or that the supplier has not configured automated response tracking.

The listing profile does not disclose factory size, R&D staff count, annual revenue, ISO certification status, or named OEM clientele. No patent portfolio, export license details, or trade show history is provided. Buyers should treat unverified claims with caution and conduct independent due diligence, including a factory audit or third-party inspection, before committing to volume orders. The supplier's geographic concentration in Ningbo, a hub for electronics manufacturing and export, offers logistical advantages but does not substitute for verified quality assurance.
