Import 5-7a 13.8v Dc Regulated Power Supply — Buy in wholesale FOB from Supplier in China

The 5-7A 13.8V DC regulated power supply from Hokog Electronics Co., Ltd delivers a fixed output voltage of 13.8 volts with a current capacity ranging from five to seven amperes, suited for applications requiring stable DC power such as radio transceivers, battery charging, and industrial control systems. The source description confirms built-in overcurrent and short-circuit protection, though specific protection thresholds, response times, or crowbar circuit details are not stated. The unit features an compact enclosure design intended for benchtop or rack-mount integration, with adjustable output mentioned without clarification of whether this refers to voltage trimming or current limiting.

In the DC power supply industry, 13.8V output correlates closely with nominal 12V lead-acid battery systems, making this unit typical for float-charging and standby power applications. Standard line regulation for this class of supply typically falls within 0.1% to 0.5% for input voltage variation, while load regulation typically ranges 0.2% to 1.0%. Ripple and noise specifications, usually expressed in millivolts peak-to-peak, are not provided in the source and should be requested from the supplier. The current rating range of 5-7A suggests either a selectable model series or derating dependent on ambient temperature, which buyers must clarify before ordering.

Target buyers include electronics manufacturers, telecommunications maintenance depots, automotive diagnostic workshops, and amateur radio operators requiring clean DC power. The 13.8V fixed output suits equipment designed for automotive or battery-backed operation without the voltage drop associated with direct battery connection. Trade terms referenced include FOB and CIF shipping options, with flexible minimum order quantities claimed. No actual MOQ figure, lead time, unit price, or confirmed certification documentation appears in the source data, and buyers must obtain these details directly from Hokog Electronics before finalising procurement.

Hokog Electronics Co., Ltd is located at No.238 Xueyuan Road, Haishu District, Ningbo 315000, Zhejiang Province, China. The imported supplier tier and harbour trust level indicate basic platform registration without extended verification signals. The zero percent response rate and absence of recorded response hours suggest communication may be delayed or irregular, requiring buyers to follow up proactively and consider alternative contact channels such as direct email or telephone to the Ningbo address provided.

The source description contains no information about factory floor space, engineering staff count, years of operation, annual turnover, or client portfolio. No ISO certification, factory audit, or quality management system detail is confirmed in the source data, despite mention of CE and ISO in the original text that appears to be platform-generated rather than supplier-verified. Buyers should request a current ISO 9001 certificate, a CE declaration of conformity with the applicable EMC and Low Voltage Directives, and evidence of in-house testing capability before relying on compliance claims. Ningbo's electronics manufacturing cluster offers access to component supply chains and port logistics, but this regional advantage does not substitute for individual supplier due diligence.
