Custom OEM Industrial Power Supply Factories & Factory in Portsmouth

Yes. All Varnix DC-DC converters, pure sine wave inverters, and rectifier systems conform to CE, RoHS, and FCC directives, and are supplied with Declarations of Conformity suitable for UKCA compliance documentation. Our switching designs integrate multi-stage input EMI filtering, common-mode chokes, and TVS surge suppression to pass EN 61000-6-2 (industrial immunity) and EN 61000-6-4 (industrial emissions), ensuring they operate harmoniously alongside sensitive naval radio receivers, GPS antennas, and dockside communications.

Standard coated electronics rapidly corrode when exposed to the high salt mist and constant humidity of Portsmouth Harbor and the Solent. Varnix modules utilize high-pressure die-cast aluminum alloy casings pre-treated with anti-corrosion chemical passivation. Internally, the circuit board is 100% immersed and hermetically encapsulated in military-grade, flame-retardant epoxy or silicone thermally conductive resin. This creates an impenetrable barrier against salt crystals, water immersion up to 1 meter, sand ingress, and severe mechanical vibration.

For standard catalog models (such as our 12V/24V stabilizers or 1440W step-up modules), our MOQ starts at just 1 to 5 units for testing, evaluation, and engineering prototypes. For full OEM customization—such as custom pre-set output voltages (e.g., exactly 13.8V, 28V, or 56V), customized wire gauge harnesses, proprietary mounting plates, or laser-engraved branding—custom project runs typically start from 50 to 100 units depending on complexity.

While high-frequency inverters are lighter, our low-frequency toroidal transformer inverters (such as the YUCOO 1500W pure sine series) provide extraordinary surge resilience—handling continuous motor, compressor, and pump inrush currents up to 200% to 300% of nominal rating without triggering fault shutoffs. The toroidal iron core topology also produces lower magnetic leakage, cleaner pure sine waveforms (THD < 3%), and superior thermal mass, making it exceptionally reliable aboard marine vessels operating in rough sea states.

Standard prototype and catalog sample orders are dispatched within 2 to 4 business days via DHL/FedEx/UPS Express, arriving at facilities in Portsmouth, Southampton, or Fareham within 5 to 7 business days. Batch production orders (500–5,000 units) are completed in approximately 15 to 25 calendar days. We offer full maritime sea freight directly into Southampton Port or London Gateway, as well as air freight with comprehensive DDP (Delivered Duty Paid) handling, meaning customs duties, VAT, and local inland transport are fully managed on your behalf.

Absolutely. In marine and heavy plant applications, starting massive diesel engines can cause battery bus voltages to sag momentarily to as low as 8V or 9V, followed by significant inductive load dumps. Our wide-input buck-boost converters (such as our 8V-40V to 13.8V 15A regulator) feature fast dynamic feedback loops that sustain a steady, unvarying output without rebooting or resetting delicate navigation electronics, chartplotters, and Starlink satellite terminals.
