What is the minimum order quantity for Eltrum DC-DC converters?

Most standard converter and charger models start from 5 units, which lets engineers validate samples before volume orders. Selected high-power models are available from 1–2 units, and some industrial isolated modules start at 50 units.

Do you offer OEM and ODM customization?

Yes. Shenzhen Eltrum Electronic Co., Ltd. offers OEM service, design service and buyer-label production, including custom input ranges, output voltage/current, connectors, housings, RS485 communication and charging curves.

Which certifications do your products carry?

Our converter and charger series are produced to CE and RoHS requirements under an ISO 9001 quality management system. Certificate copies can be requested by email for specific models.

When should I choose a buck-boost converter instead of a buck converter?

Choose buck-boost when your input voltage can fall below and rise above the required output, for example a 12V battery that sags to 9V under load and rises to 14.6V while charging. A buck converter only works when input stays above output.

Can a DC-DC battery charger charge a LiFePO4 house battery from a vehicle alternator?

Yes. A battery-to-battery DC-DC charger regulates the alternator or starter battery input and delivers a controlled CC/CV profile (for example 14.6V for 12V LiFePO4), protecting both batteries in RV, truck and marine dual-battery systems.

What payment and delivery terms are accepted?

We accept T/T, PayPal and Escrow in USD or CNY, with FOB or EXW delivery terms.
