China Top DC DC Power Module Factories & Factory in the Limassol Market

Cyprus summer conditions present a significant challenge for industrial electronics. Standard converters enclosed in metal cabinets without active cooling frequently hit internal temperatures above 65°C. Eltrum mitigates this by designing with low on-resistance MOSFETs (ultra-low Rds(on)) that minimize conduction loss, operating at over 94–96% peak efficiency. Additionally, our housings are cast from heavy-gauge aluminum alloy with integrated heat-dissipating cooling fins. Our marine and industrial models feature thermally conductive epoxy silicone potting that transfers heat evenly across the entire surface while completely sealing active components against humidity and marine salt air.

Yes. As the Republic of Cyprus is an EU Member State, all electrical equipment must comply with the Low Voltage Directive (LVD 2014/35/EU) and Electromagnetic Compatibility Directive (EMC 2014/30/EU), as well as RoHS Directive (2011/65/EU as amended by 2015/863). Eltrum power products are engineered and tested in accordance with relevant EN harmonized standards. Full Declarations of Conformity (DoC) and accredited laboratory test reports are provided to your customs clearing broker in Limassol Port to ensure rapid customs release.

For urgent engineering trials and low-volume sample orders (5 to 50 units), we ship via express air freight (DHL, FedEx, UPS) directly to Larnaca or Paphos airports, reaching your Limassol facility in 4 to 7 business days. For volume container production (commercial fleets, municipal orders, large solar farms), cargo is dispatched via ocean freight from Shenzhen Port (Yantian or Shekou) directly to the Port of Limassol. Ocean transit time typically ranges between 22 and 30 days depending on carrier sailing schedules. We support standard Incoterms including EXW, FOB Shenzhen, CIF Limassol, and DDP (Delivered Duty Paid).

Absolutely. While our standard catalog offers fixed parameters for standard 12V, 24V, 36V, 48V, and 72V LiFePO4, NMC, and lead-acid chemistries, our R&D engineering division regularly produces custom voltage and current profiles. For example, if your application utilizes an unconventional 7S lithium pack requiring a 29.4V cutoff, or a 16S pack set to 58.4V with a specific absorption-to-float current step down, we modify the micro-controller firmware and resistor networks directly at our Shenzhen factory. Custom orders can be initiated with minimum order quantities as low as 20 to 50 units.

In marine applications, galvanic isolation is essential for safety and reliability. Non-isolated converters share a common negative ground between the input (such as 24V propulsion batteries or engine alternators) and the output (sensitive 12V navigation electronics, radar, radios). In a salty marine atmosphere, any ground loop or potential mismatch between different electrical devices creates stray DC currents that run through the hull or grounding bus, causing severe galvanic corrosion that damages expensive metal hardware. An isolated DC-DC converter incorporates an internal high-frequency transformer barrier (typically rated for 1500VDC isolation), eliminating ground loops, breaking noise pathways, and isolating sensitive navigational electronics from electrical spikes generated by engine starters or anchor winches.

To support design engineering and prototype validation, our baseline MOQ for standard catalog converters is set at only 5 units. For specialized high-wattage modules (such as our 1500W buck-boost or 1000W chargers), we can accept evaluation sample orders of 1 to 2 units. Payment terms for sample and trial shipments include secure T/T wire transfer and PayPal in USD or EUR. For established OEM container volume contracts, we provide flexible commercial credit arrangements and staged milestone payments.
