Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Power over Ethernet (PoE) technology, with its revolutionary "dual-use in one wire" design, integrates power and data streams into a single network cable, significantly reducing the deployment cost and complexity of Internet of Things (iot) devices. ADI (Analog Devices) 's PoE interface controller, as the "energy efficiency heart" of power supply equipment (PSE) and power receiving equipment (PD), integrates high-precision power management, multi-protocol compatibility, and ten-level circuit protection mechanisms. Supports full-power scenarios ranging from 13W (IEEE 802.3af) to 90W (ADI LTPoE++) 15. However, the accelerated technological iteration and supply chain fluctuations have turned a large number of brand-new, unused ADI PoE chips into "silent assets" for enterprises - they occupy cash flow and face the risk of rapid depreciation. Shenzhen Mingjiada Electronics Co., LTD., relying on its 15-year accumulation of high-end chip recycling technology and the premium model of globally scarce models, has opened up an efficient recycling channel for the entire range of Analog Devices (ADI) PoE controllers for the industrial chain, enabling idle chips to regain their technical life and commercial value.

The core recycling categories of Mingjiada

PoE Power Supply Equipment (PSE

The ADI Power Supply Equipment (PSE) controller supports power over Ethernet at multiple power levels: IEEE PoE (13W, 802.3af), IEEE PoE+ (25.5W, 802.3at), IEEE PoE++ (71.3W, 802.3bt) and ADI LTPoE++ (90W) standards. The PSE controller is responsible for detecting the receiving device (PD) and classifying it, as well as providing an appropriate amount of power to the PD through the Ethernet cable.

PoE Power receiving device (PD

ADI's Power Receiving Device (PD) controllers support multiple power over Ethernet (PoE) power levels: IEEE PoE(13W), IEEE PoE+ (25.5W), IEEE POE ++ (71W), and ADI LTPoE++ (up to 90W) standards. The PD controller is mainly responsible for providing the correct characteristics and classification for the power supply equipment (PSE), so that the PSE can supply the appropriate amount of power to the PD through the Ethernet cable.

2. Mingjiada Recycling System: Dual-driven by scientific assessment and global circulation

Triple technical Appraisal: Cracking the Value Code of PoE Chips

Mingjiada has established an industry-leading evaluation model to precisely quantify the value of chips

Electrical performance verification: The hierarchical response speed and surge suppression capability were tested through Keysight oscilloscopes to screen out full-function chips that can meet the harsh industrial environment.

Protocol compatibility test: Verify the compliance with the IEEE 802.3bt Type 4 standard based on the Ixia analyzer to ensure the interconnection and interoperability of multi-brand devices;

Scarcity premium: Due to the surging demand for new energy vehicles, the recycling price of automotive-grade models (such as the MAX246xxE certified by AEC-Q100) can reach 65% to 80% of the market price in circulation.

Global ultra-fast response network

Relying on the Shenzhen bonded warehouse and the Hong Kong international transshipment hub, achieve:

Asia-pacific region: 24-hour door-to-door pickup, covering the urgent handling needs of customers in Japan, South Korea and Southeast Asia.

Europe and America channel: Chips are transshipped and cleared through Hong Kong, and the inbound inspection is completed within 72 hours.

ESD protection system: Full electrostatic shielding packaging and constant-temperature transportation to ensure zero damage to the chip.

Compliance and privacy protection

Mingjiada strictly limits the scope of recycling and eliminates illegal sources of goods

Source compliance: Only accepts unopened slow-stock materials, EOL project surplus materials and spare parts of discontinued models from agents/factories.

Data erasure: Provide physical demagnetization services for industrial controllers with configuration parameters and issue destruction reports.

3. Why choose Mingjiada: The Dual Breakthrough Advantages over Traditional Recycling

A revolution in the speed of capital recovery

Payment upon inspection: Full payment is made within 48 hours of arrival, which is three times faster than the industry average. Cross-border settlement in US dollars, euros and RMB is supported.

A 50% deposit in advance: For large orders, half of the payment can be obtained in advance, alleviating the cash flow pressure on enterprises.

Global compliant circulation network

12 countries' pick-up coverage: Delivery centers are set up in Japan, Germany, the United States, etc., taking on the DDP customs clearance risk.

Blockchain traceability: The entire process of chip circulation is recorded on the chain, meeting the requirements of the EU WEEE Directive and domestic recycling resource management.

Mingjiada Electronics has upgraded the recycling of ADI PoE controllers from a cost center to a value chain engine through a three-dimensional model of "technical appraisal × global network × carbon value conversion".
