Galvanic Separation for Extreme Noise Immunity
Shenzhen Eltrum Electronic Co., Ltd. specializes in high-reliability isolated DC-DC converters engineered with integrated magnetic transformers. Unlike non-isolated topologies, our isolated modules break ground loops and eliminate hazardous voltage spikes, guaranteeing safe operation in sensitive industrial automation, telecom infrastructures, and high-voltage battery environments.
With an expansive input capability spanning 18V up to 90V DC and regulated outputs including 5V, 12V, 13.8V, 19V, and 24V, our power supplies deliver superior voltage regulation, low output ripple, and ruggedized protection against over-current, short-circuit, and reverse polarity.

Zero Ground-Loop Noise
Transformer isolation physically separates input and output grounds, stopping signal interference in sensitive audio, radio, and measurement equipment.
High Dielectric Withstand
Tested up to 1500V DC isolation barriers to protect delicate low-voltage logic controllers from primary-side high-voltage surges and load dumps.
Industrial-Grade Reliability
Constructed in flame-retardant extruded aluminum casings filled with thermally conductive epoxy resin for shock, vibration, and water resistance.
Standardized Production & Strict Quality Control
Every isolated power module is fabricated and verified in our Shenzhen facility using automated SMT, rigorous burn-in cycles, and full-load electrical testing.
High-Precision SMT & Automated Assembly
Our standardized production lines maintain tight component tolerances and uniform solder joint reliability across all high-frequency isolated transformer assemblies.
100% Full-Load Burn-In & Dielectric Testing
All isolated DC-DC units undergo rigorous hi-pot voltage withstand screening, thermal stress evaluation, and full electrical parameter validation prior to shipment.
