Waterproof Power Supply Factory & Exporter for the Geneva Market

Yes. Under the Swiss Ordinance on Low-Voltage Electrical Equipment (NEV / SR 734.26), Switzerland aligns directly with EU Directive 2014/35/EU (LVD) and 2014/30/EU (EMC). Products bearing valid CE conformity, backed by complete technical construction files and test reports against harmonized EN standards (such as EN 62368-1, EN 61347, and EN 61000-3-2), can be legally placed on the Swiss market without mandatory Swiss-specific safety marks (SEV mark). Keldan provides full declaration dossiers and accredited third-party test reports for audit verification.

Switzerland and China maintain an active Free Trade Agreement (FTA). For electrical switching power supplies and transformers classified under HS Code 8504.40, we provide official Form S Certificates of Origin issued by Chinese customs authorities. This enables Swiss importers in Geneva, Lausanne, or Zürich to clear goods at preferential or zero-percent customs duty rates. All commercial invoices, packing lists, and transport manifests are formatted in compliance with Swiss Federal Customs Administration (FCA) requirements.

We employ high-thermal-conductivity (1.2 W/m·K) two-part silicone elastomeric and modified polyurethane (PU) resins. Unlike rigid epoxy potting compounds that crack under cryogenic thermal contraction, our potting compound maintains elastic memory and structural flexibility across a temperature span from -40°C to +85°C. The potting process occurs inside automated vacuum chambers to completely eliminate micro-bubbles and air voids, preventing internal condensation when warm equipment cools rapidly in damp Geneva lakeside environments.

For urgent prototype or urgent engineering maintenance requirements, direct air freight to Geneva Airport (GVA) or Zürich Airport (ZRH) takes approximately 4 to 7 business days via DHL, FedEx, or dedicated air forwarders. For standard high-volume containerized B2B shipments, ocean transit to European gateways (Rotterdam, Hamburg, or Genoa) followed by bonded rail or truck transit to Geneva customs depots takes roughly 28 to 35 calendar days.

Absolutely. As a TÜV Rheinland-verified custom manufacturer, design-based and sample-based customization is a cornerstone of our business. We regularly build specialized configurations—such as custom 36V or 72V DC rails, push-in terminal blocks (WAGO or Phoenix Contact compatible), custom cable lead lengths, laser-etched private labels with your Swiss corporate brand, and project-specific packaging. Standard models have minimum order quantities (MOQs) starting from single sample units; custom OEM production runs typically begin at 50 to 100 units depending on the engineering scope.

Reliability is engineered from component selection through post-production screening. We strictly specify 105°C-rated electrolytic capacitors with calculated operating lives exceeding 50,000 hours under rated thermal conditions. Every single unit leaving the production floor undergoes a multi-hour 100% full-load burn-in aging test with automated power cycling. Any component exhibiting marginal drift or thermal hot spots is isolated and rejected prior to final QA packaging.
