Shenzhen Eltrum Electronic Co., Ltd. is committed to being an international tier-one provider of advanced power solutions. We design, engineer, and manufacture industrial-grade AC-DC power supplies, non-isolated and isolated DC-DC converters, and multi-stage battery charging systems.
With a portfolio of more than 500 active standard models, our products deliver stable, clean, and efficient DC power across alternative energy systems, industrial automation, telecommunications, robotics, commercial vehicle conversions, marine electrical systems, and medical mobility equipment.
Isolated DC-DC conversion technology forms the core of our technical heritage. Over the last decade, our team has integrated synchronous rectification, wide-input voltage tolerance, and potted IP65/IP68 ingress protection into every series we produce.
Combining design flexibility, high component standards, and rigorous testing protocols to serve B2B buyers worldwide.
Our dedicated R&D team customizes input voltage windows, output voltages, dynamic current limits, communication protocols (RS485 / CAN), and thermal chassis packaging to fit proprietary OEM mechanical constraints.
We provide full-spectrum voltage conversion solutions, eliminating the hassle of coordinating with multiple power vendors for complex systems.
Engineered for high vibration, wide temperature swings (-40°C to +85°C), and harsh moisture exposure across heavy machinery, boats, and outdoor cabinets.
Every converter and charger leaves our factory only after undergoing multi-stage verification to ensure near-zero field failure rates.
Strict verification of incoming semiconductors, magnetic cores, capacitors, and aluminum enclosures before reaching the assembly floor.
Automated high-speed surface-mount placement followed by optical inspection to ensure precision soldering without bridges or voids.
100% full-power burn-in testing under controlled thermal conditions to weed out early infant mortality defects before encapsulation.
Final ripple, noise, voltage regulation, insulation resistance, and dielectric withstand tests prior to export carton packaging.
Shenzhen Eltrum Electronic Co., Ltd. products are deployed across more than 130 countries worldwide, serving long-term partners in the USA, Canada, Germany, the UK, Australia, Japan, and South Korea.
Whether you require standard samples for bench evaluation or customized voltages for an upcoming OEM volume roll-out, our technical engineers are standing by to assist you.
