Engineered Reliability & OEM Customization by Eltrum
As a verified manufacturing specialist since 2015, Shenzhen Eltrum Electronic Co., Ltd. designs and fabricates industrial-grade non-isolated step-down (buck) DC-DC converters built to handle severe electrical noise, load dumps, and harsh environmental operating temperatures from -40°C to +85°C.
Every converter series utilizes synchronous rectification topology to maximize electrical conversion efficiency up to 96%, effectively minimizing thermal stress without requiring complex cooling infrastructure. Standard housings feature die-cast aluminum alloys with 100% silicone/epoxy potting for IP68 dust and waterproof resilience.
Rigorous Protection
Built-in over-current, short-circuit auto-recovery, input under-voltage, over-temperature, and transient surge voltage protection.
Certified Quality
Conforms strictly to CE (EN 61000 series) and RoHS environmental directives under an ISO 9001 certified manufacturing workflow.
Flexible OEM Support
Custom cable lengths, automotive wiring terminals, private-label branding, customized fixed voltage levels, and tailored packaging.
