LEEYEE is a surge protection device manufacturer supplying AC, DC/PV and signal SPDs for distributors, OEM brands, panel builders and electrical projects. As a surge protection device supplier, we support model selection, document confirmation, OEM requirements and batch quotations.
CE, TÜV, CB, RoHS and related document availability is confirmed by exact model.
LEEYEE provides AC, DC/PV and signal surge protective devices for different systems, market voltages and B2B procurement applications.
DIN-rail SPDs for distribution boards, control cabinets and OEM electrical equipment.
Document availability depends on the exact model, voltage, SPD Type and poles.
DC surge protection for PV strings, combiner boxes, inverter inputs and industrial DC systems.
Final selection depends on system voltage, Voc, grounding and installation position.
Surge protection for RS485, PLC, sensors, telemetry and industrial communication lines.
Selection depends on the exact interface, nominal voltage, current and application.
LEEYEE supports different product, document and quotation paths for distributors, OEM brands, panel builders and project procurement teams.
Review core ranges, market voltages, documents, samples and a practical stocking mix.
Confirm logo, product label, model naming, packaging, instructions and document compatibility.
Send the specification or BOM for Type, voltage, poles, position and document review.
Review LEEYEE’s component validation, impulse testing, thermal-stability checks, 11-step production flow and order-specific quality controls in one manufacturer verification section.
MOV and GDT components are checked with automated equipment before final assembly to support consistent electrical performance across the approved production configuration.
Buyer confirmation should match the exact model, voltage, Type, pole configuration and document scope.
The impulse-test environment is used to review applicable surge-discharge behavior and protection performance for the product configuration.
The applicable waveform, test level and report must be confirmed against the exact product model.
Thermal-stability testing reviews product behavior under prolonged electrical stress and supports evaluation of the thermal-disconnection design.
Thermal-test information must be reviewed with the exact model, internal design and applicable standard.
Follow the main stages from incoming materials and component processing through assembly, testing, packing and finished-goods storage.
01Incoming raw material storage and material preparation.
02Plastic housing and component forming by injection molding.
03Metal contact and conductive part stamping.
04Small components and accessory pre-assembly.
05Adhesive application and component fixing.
06Electrical connection soldering and terminal processing.
07Product marking, model printing and surface identification.
08SPD module plugging and semi-finished product assembly.
09Electrical performance inspection and quality verification.
10Finished product packing, labeling and order preparation.
11Finished goods storage before shipment.

Switch between the three controls used to verify materials, private-label details and the final order configuration without stacking three long evidence blocks.
Raw materials and purchased components are reviewed before they enter the approved SPD production process. The inspection record provides concrete evidence instead of a generic quality claim.
Only reviewed materials and components should enter the approved production process.
Open full-size inspection record
Private-label orders are reviewed as a complete configuration. Product appearance, electrical information, branding and packing content should be aligned before batch production begins.
Artwork and model parameters should be approved before OEM batch production.
Open full-size OEM confirmation image
Finished products are checked against the approved order before release. Packing information should match the exact SPD configuration rather than relying on a generic carton label.
Packing verification helps reduce model, quantity and documentation errors before shipment.
Open full-size packing imageSwitch between certification and test-document evidence and real LEEYEE installation cases. Each image remains large enough to review and can be opened at full size.
Available certification, test and technical documents are reviewed against the exact product configuration requested by the distributor, OEM brand, panel builder or project buyer.
Certification and test-document availability depends on the exact model, voltage, SPD Type, pole configuration, branding configuration and manufacturer information. Submit your specification for confirmation.
LEEYEE surge protective devices are installed in real distribution, control, solar PV, industrial DC, signal and monitoring systems.
Application requirements vary by system voltage, grounding arrangement, installation position and applicable project standard. Submit your system specification for model confirmation.
Include the application, system voltage, SPD Type, poles, quantity, certification requirement and project timing.
Prepare the information needed for a useful model, document and quotation response.
Brand clarification: LEEYEE is the product brand. CNSPD.com is LEEYEE’s surge-protection platform for global buyers.
Provide the essential information so the first response can focus on suitable models, available documents and quotation conditions.
