AC přepěťová ochrana
For another AC starting point, VSP1-D20/2(S) lists In 10kA and Imax 20kA. Choose by system voltage, protection level and installation requirements.
Industrial DC requirements
Send the circuit voltage, earthing and application for model review. A solar PV rating alone does not establish suitability for every DC distribution system.
Solar PV surge protection
Prozkoumejte 600V PV and the linked 1000V / 1500V models. Confirm Ucpv, protection modes and coordination for the installation.
From component review to OEM packing.
VIOX’s published manufacturing workflow covers material control, assembly, electrical verification and packing. Agree the SPD-specific inspection plan with your order.
Component & configuration review
Match the selected product reference to the order. For an SPD, discuss MOV, housing, terminals and thermal-protection requirements.
Assembly & workmanship
VIOX’s general assembly checkpoints address product configuration and workmanship. Confirm the applicable checkpoints for your selected SPD.
Inspection & document review
Define the electrical checks and any required performance reports before production release. Routine inspection and surge type testing are separate requirements.
Marking & packaging
Align labels, model references, quantities and packaging with the approved order and private-label artwork.
SPD testing, standards & supporting documents.
Start with the exact model, then request the documents needed for your market. The standards below are references in published product data—not a certificate gallery.
| Product record | Published reference | Dokumenty k vyžádání |
|---|---|---|
| VSP1-D20/2(S) VSP1-C40/2(S) | IEC 61643-11 EN 61643-11 | Exact model, ratings, applicable edition and available supporting report. |
| VSP1-C40PV/3(S) 1000V(D4) / 1500V(D4) | IEC 61643-31 | PV model and voltage scope, issuing body, report number and applicable test results. |
8/20 μs & 10/350 μs
Ask for evidence supporting In / Imax and, where applicable, Iimp for the selected model. A product rating does not prove that a manufacturer owns an in-house test laboratory.
Protection & safety review
Include voltage protection level, thermal protection, operating conditions and specified backup protection in the technical review.
Certification is model-specific
Check model coverage, manufacturer identity, issuing body and validity. An IEC type designation or a reference to UL is not proof of UL Listing.

Surge protection within a broader electrical range.
VIOX offers SPDs alongside complementary low-voltage protection, switching and connection products. This can simplify sourcing for distributors, panel builders and brands purchasing multiple product families.
Unlike a surge-protection-only sourcing brief, a VIOX inquiry can include the wider panel bill of materials. Common sourcing does not by itself establish electrical compatibility: backup protection and coordination still need design review.
How to evaluate an SPD manufacturer.
Use a short, model-specific review before committing to bulk supply.
- Match the electrical system. Confirm AC or DC/PV suitability, continuous voltage, protection modes and earthing.
- Check performance evidence. Review the required type, In / Imax / Iimp, Up and applicable test reports.
- Check certificate scope. Match the exact model, voltage, manufacturer and issuing body—not just a logo.
- Understand production and testing. Ask which operations and tests are in-house and which use outside providers; arrange an audit if required.
- Schvalte objednávku. Review samples, artwork, inspection requirements and repeat-order references.
Výrobce SPD questions.
Product scope, private-label supply and the documents that matter before ordering.
Is VIOX an SPD manufacturer in China?
VIOX Electric supplies surge protective devices and OEM/private-label electrical products from Yueqing, Zhejiang, China. This page brings together its published SPD models, order capabilities and technical-document review process.
Where is VIOX located?
VIOX is based in Yueqing, Zhejiang, China. Contact the team to arrange a factory visit or discuss the production and inspection scope for your SPD order.
Does VIOX supply Type 1 and Type 2 SPDs?
The published VSP1-C40/2(S) record identifies Type 2 protection. The VSP1-C40PV/3(S) 1000V(D4) and 1500V(D4) records identify combined Type 1+2 protection. Availability and supporting test evidence must be checked for the exact model; this is not a claim that every series has every type.
Does VIOX supply solar PV SPDs up to 1500V DC?
Yes. The published VSP1-C40PV range includes 600V, 1000V and 1500V DC product records. The VSP1-C40PV/3(S) 1500V(D4) record lists a maximum continuous operating voltage of 1500V DC. Select against the actual PV system design and model datasheet.
Can I use a PV SPD in another DC system?
Do not assume interchangeability. Send the DC voltage, earthing arrangement, fault conditions and application so suitability can be reviewed for a specific device.
Does VIOX offer OEM and private-label SPD orders?
Logo, marking, label and packaging requirements can be reviewed for an existing SPD model. Housing changes, special colors and document customization require a separate feasibility review. MOQ and lead time are confirmed with the quotation.
Which standards are listed for VIOX SPDs?
The VSP1-D20/2(S) and VSP1-C40/2(S) records reference IEC 61643-11 and EN 61643-11. The linked VSP1-C40PV models reference IEC 61643-31. A published standards reference is not itself a certificate, test report or UL listing; request the applicable model-specific documents.
How can I request SPD samples and a quotation?
Send a model or application, estimated quantity and destination market, and state whether you need samples or private-label packaging. Add system voltage, SPD type and surge-current requirements if known. Sample arrangements and delivery timing are quoted for the order.
