Import 35v-300v Programmable Dc Power Supply An51 — Buy in Bulk from Supplier in China

The AN51 from Ainuo Instrument is a programmable DC power supply spanning 35V to 300V output, built on the same high-frequency PWM and phase-shifted full-bridge conversion technology as the broader Ainuo range. Programmability implies automated control beyond the ten memory groups of the base series, with the source noting an intuitive interface accessible to both experienced engineers and new operators. Protection features include over-voltage, over-current, and short-circuit protection, though trip thresholds and response times are not numerically specified. The unit targets electronics manufacturing, automotive testing, and research laboratory environments where repeatable, software-controlled power profiles are required.

The programmable architecture distinguishes the AN51 from manually controlled bench supplies, enabling sweep sequences, timed profiles, and integration with automated test equipment. The phase-shifted full-bridge topology supports the higher efficiency and power density needed for continuous operation in production test racks. Multiple protection layers suggest fault-tolerant design for unattended operation, a critical requirement in round-the-clock manufacturing lines. Typical programmable supplies in this voltage class offer voltage programming resolution of 10mV or finer, with closed-loop feedback maintaining set points under load transients.

Buyers in automotive testing will value the unit for ECU development, battery simulation, and component endurance testing, while research laboratories employ similar supplies for material characterisation and prototype validation. The source claims ISO and CE compliance, though no certificate numbers or issuing bodies are provided. As with the harbour-tier listing status and zero recorded response rate, direct supplier engagement is necessary to confirm programme memory depth, communication protocol support, and whether programming is via front panel, remote digital interface, or both. Import planning should account for verification of all claimed conformity markings before customs clearance.

Ainuo Instrument operates from No.134 Zhuzhou Road, Qingdao, Shandong Province, 266101, China. The harbour trust tier indicates basic listing verification with no additional assurance levels attained. Platform data shows a 0.00% response rate and zero average response hours, meaning prospective buyers cannot rely on messaging alone and should obtain direct contact details for telephone or email follow-up. No information is provided about factory size, R&D staff, production lines, or annual turnover.

The AN51 listing positions Ainuo Instrument as a supplier of programmable test equipment for industrial and research markets. The source description references ISO and CE compliance without elaboration, and mentions flexible minimum order quantities without stating values. Buyers should treat these as unverified claims requiring documentation. The identical address to the AN50 series listing suggests common corporate ownership or manufacturing base, though this does not confirm that Ainuo Instrument manufactures rather than sources the AN51. Due diligence should include a factory assessment or third-party audit request, particularly for buyers requiring supply chain traceability for automotive or aerospace end customers.
