Committed to Power Engineering Excellence
Shenzhen Eltrum Electronic Co., Ltd. is a dedicated designer and manufacturer of switch-mode power supplies, DC-DC voltage regulators, battery charging systems, and high-voltage power converters. Established in 2015 and headquartered in the advanced manufacturing hub of Shenzhen, China, we operate an onsite-inspected and third-party verified facility serving international OEMs, engineering integrators, and industrial distributors across the globe.
Our product portfolio encompasses more than 500 standardized models engineered to meet rigorous electrical requirements in renewable alternative energy, telecommunications base stations, automated mobile robots (AMR), industrial automation, material handling, and electric commercial vehicles. Through deep topology expertise and customer-first technical support, we help clients overcome ground-loop interference, wide battery voltage drops, and severe thermal challenges.
High-Precision SMT Production
Automated surface mount lines and strict component placement ensure consistent soldering quality and minimal parasitic inductance for high-frequency conversion.
Full-Load Burn-In & Inspection
100% aging burn-in and functional validation racks verify operating temperature, voltage stabilization, and transient load response under full rated capacity.
Core Product Capabilities & Topologies
From transformer-isolated telecom units to waterproof IP68 automotive stabilizers, our modular engineering accommodates specific electrical and mechanical demands.
DC-DC Battery Chargers
Battery-to-battery charging modules engineered to charge auxiliary or house lithium/LiFePO4 battery banks safely from vehicle alternators or fluctuating DC buses.
- 8V–90V ultra-wide input voltage ranges
- Configured CC/CV algorithm curves (14.6V, 29.2V, 43.8V, 58.4V)
- RS485 communication & smart alternator compatibility
Isolated DC-DC Converters
Galvanically isolated conversion modules built to eliminate common-mode ground noise, loop currents, and electrical hazards in telecom and industrial machinery.
- 1500VDC dielectric withstand voltage rating
- Input configurations: 18–36V, 36–75V, and 18–90V
- Dedicated 5V, 12V, 24V isolated system rails
Buck-Boost Voltage Regulators
Seamless 4-switch synchronous buck-boost topologies providing stable regulated voltage even when the input fluctuates significantly above and below nominal targets.
- High efficiency operation up to 96%
- Power capacities ranging from 36W to 1500W
- Die-cast aluminum alloy shell with thermal potting
End-to-End QA/QC Verification Process
Shenzhen Eltrum Electronic Co., Ltd. implements strict quality gates at every production stage to ensure zero-defect reliability in demanding field applications.
Incoming IQC Inspection
Parametric testing on MOSFETs, planar transformers, inductors, and high-temp electrolytic capacitors before entering the SMT magazine.
SMT & AOI Verification
Automated optical inspection post-reflow to verify solder fillets, component alignment, and polarity integrity on every PCB assembly.
Vacuum Potting & IP68 Sealing
High-conductivity epoxy/silicone vacuum potting prevents air voids, ensuring IP67/IP68 waterproof rating and shock resistance.
100% Full-Load Burn-In
Each production unit undergoes continuous burn-in testing under dynamic full-load cycles to eliminate infant mortality defects.
