Yidian
Power
Microwave high-voltage power supplies and lithium battery chargers presented under the Yidian brand. The CMH contracting entity is 深圳市视麦电气技术有限公司, registered in Shenzhen in 2023 with power-electronics manufacturing and import/export in its scope. Product ratings below come from supplier material and are subject to a model-specific specification.
Model-level materials, with open checks visible.
Microwave High-Voltage Power Supplies
The workbook lists oil-, air- and water-cooled units, including MEP-1250W, MEP168P, MP1300, MEP3000PGH, MEP-188 and MEP186. Several entries state approximately 4–4.65 kV DC and adjustable power. Voltage polarity, magnetron matching, duty cycle and whether a stated wattage means electrical output or RF output need a controlled specification. These are high-voltage components for qualified equipment integration.
Microwave Control & Supporting Components
MKP-3000 is listed as a ten-channel control board and MKP102 as eighteen-channel, with Modbus RTU. Magnetrons, transformers, waveguide parts and cooling components also appear in the material. A complete integrated supply scope, interlock design, registers and acceptance record have not been supplied.
Adjustable Lithium Battery Chargers
Supplier posters list K3 / YD4500 variants at a stated 4500 W, 24–92.4 V DC and 1–50 A, plus YD2800 and YD1680 variants. These maxima are not simultaneously available across the entire adjustment range: request the voltage-current-power envelope and mains/temperature derating curve. CAN capability is not confirmed by the files supplied.
L-Series Chargers
L6 is advertised at 1600 W, 180–264 V AC input, 24–76.8 V and 15–25 A. L2 / L5 posters list 660 W and 1250 W configurations. Chemistry, cell count, actual termination voltage, current and connector must be agreed per order; a matching plug alone does not establish battery compatibility.
Heat-Pump & Solar Drive Boards
Additional workbook sheets cover compressor/heat-pump drive boards and MPPT-related models. These are secondary lines pending full specifications and ownership confirmation. Nothing supplied establishes certification for grid-connected solar export.
What the registry confirms, and what stays open.
Registry-Matched Legal Entity
深圳市视麦电气技术有限公司 is active (存续), established 2023-09-25. The scope explicitly includes power electronic component manufacture, mechanical/electrical equipment manufacture, electronic and electromechanical component manufacture, and goods/technology import and export. This confirms the registered scope, not a site audit.
Engineering Detail Exists, but Needs Release Control
A five-sheet workbook contains model codes, dimensions, power ranges, cooling and control entries. Some fields disagree: the MET-WB6KW row is titled 6000 W but gives 500–3000 W; another product name says oil-cooled while its cooling field says air-cooled. Ask for a signed revision rather than selecting from the conflicting cells.
Photos Are Supplier Evidence
Assembly, testing and facility photographs have been supplied. They have not been independently dated or tied to the selected legal entity. Production location, ownership of each line, subcontracted work, throughput and quality records remain open.
Brand, Producer and Certificate Holder Need Mapping
Material also names 东莞市佰诚源电子科技有限公司 and 广东一电新能源有限公司. Their relationship to Shenzhen Shimai, and which entity produces, invoices, exports and holds each document, has not been established. The bcpower website identifies the Dongguan company; its staff and plant claims are not attributed to Shimai here.
Compliance Is Model-Specific
No original certificate, full third-party test report or declaration of conformity covering this listing's exact models has been provided. CE/RoHS symbols and patent wording on promotional images are not verification of market access, production quality or patent status.
Registry Risk and Brand Records Are Separate
The selected entity's registry scan returned zero self, surrounding and historical risk items and three change alerts (personnel/capital). Separately, a published Yunnan inspection attachment names the Yidian brand and 广东一电新能源有限公司 for a 48 V lead-acid charger, YD-4820(3A), with over-temperature protection and overcharge cut-off failures. This is not a finding against Shimai or the lithium models listed here; the brand relationship and any corrective-action evidence remain to be clarified.
What was checked — and what the check found.
No original model-specific certificate or complete test report has been sighted. Request holder, model scope, standards, report number and current status. This listing does not claim CE, UKCA, UL, ETL, RCM, ISO or patent certification for the selected entity.
One brand, a specifically identified contracting entity.
Yidian Power is the listing brand for a supplier whose CMH contracting entity has been confirmed as 深圳市视麦电气技术有限公司. Established in Shenzhen in September 2023, this active entity has manufacturing and import/export clauses in its registered scope.
The material spans two main families: high-voltage microwave power modules with control/supporting components, and lithium battery chargers for matched mobility and battery projects. Heat-pump and solar-drive boards appear as secondary lines. Product ratings are supplier statements until a released specification and test record are provided.
This page separates the registry check from production, certification and compatibility. Multiple entities occur in the source material; their responsibilities and the certificate holder for each model must be agreed before quotation. Buyers can start a technical inquiry through CMH with a defined application, quantity and destination.
Registered in 2023, reviewed for this listing in 2026.
Shenzhen entity registered
Registration date 2023-09-25. The supplied older licence shows a different address; the current registry address is used here.
Materials reviewed for CMH
56 product/facility photographs, one five-sheet workbook and one business licence supplied. Registry checked; engineering and document gaps are stated above.
Two product families, two engineering conversations.
Microwave Equipment OEMs
For heating, drying and related industrial equipment, match the power module to a defined magnetron and controlled cooling/interlock system. Ask for interface drawings, fault behavior and an agreed acceptance test.
Microwave Service & Retrofit Integrators
For replacement projects, compare input supply, voltage/current polarity, filament power, grounding, mechanical envelope and cooling. Similar wattage is insufficient to establish drop-in replacement.
Golf-Cart & Low-Speed Vehicle Integrators
A charger matching project starts with battery chemistry, series count, full-charge voltage, BMS behavior and environmental conditions. Supplier-stated applications do not prove an approved match to a vehicle.
Battery-Pack OEMs & Industrial Mobility Builders
Require a charging profile and battery/BMS approval for the exact pack. Low-temperature heating, low-voltage wake-up and zero-voltage starting claims need defined limits and validation.

Frequently Asked Questions
What does the CMH Verified mark cover?
The selected legal entity's registry identity, active status and registered manufacturing/import-export scope were checked. It does not mean a site audit, tested product performance, validated brand relationships or verified product certification.
Is every Yidian product made by Shenzhen Shimai?
That has not been established. Multiple company names appear in the material. Request a model-to-producer-to-certificate-holder mapping and manufacturing agreement if different entities are involved.
Are the chargers universal?
No universal compatibility is claimed. Match battery chemistry, cell count, charge profile, BMS and connector pinout, and obtain validation for the exact battery/device configuration.
Is the 6000 W microwave model specification confirmed?
No. The workbook title and power-range field conflict. Ask for a corrected released specification and test conditions before using that rating.
Which certifications are verified?
None for the listed models. Promotional marks and a patent string have been seen, but original documents and their applicability have not been confirmed.
What is the public inspection record?
A published inspection attachment names a separate company, 广东一电新能源有限公司, and the Yidian brand for YD-4820(3A), a 48 V lead-acid charger. It cannot be attributed to Shimai or all Yidian products without establishing the relationship. Ask for the original notice, response and corrective-action records.
Talk to Yidian Power directly.
For a microwave project, send the magnetron type, required output, mains input, cooling and control interface. For a charger project, send battery chemistry, cell count, full-charge voltage, current, BMS protocol, connector pinout, quantity and destination. Ask for the producing entity and documents covering that exact configuration.
