Eliminate destructive ground loops, achieve complete galvanic isolation up to 3000V DC, and protect sensitive industrial microelectronics across high-voltage 18–90V battery buses.
Hardware engineers and systems integrators face harsh electrical noise, common-mode ground transient spikes, and fluctuating battery banks. A non-isolated converter shares a common ground conductor between its input and output, which makes downstream microcontrollers, CAN bus lines, and sensitive sensors vulnerable to destructive overvoltage spikes.
Zero Common Impedance
Industrial machinery and electric vehicle chassis create ground potential differences. Transformer isolation severs ground loops, preventing stray circulating currents from inducing measurement artifacts, data bus corruption, and catastrophic component failure.
Up to 3000V DC Insulation
In 48V, 72V, 96V, and 300V traction packs, physical dielectric separation protects low-voltage human interfaces and 5V/12V electronics from high-voltage flashovers caused by emergency stop disconnections or inductive kickback.
Ground-Independent Design
An isolated DC-DC converter allows system designers to create positive-floating, negative-floating, or inverted voltage potentials. This is essential for telecommunication base stations (-48V DC bus conversion to +12V DC) and medical telemetry.
High CMRR & Low Interwinding C
Shenzhen Eltrum Electronic Co., Ltd. incorporates low-capacitance planar magnetics with primary-to-secondary Faraday shields. This suppresses high dv/dt switching transients generated by silicon carbide (SiC) and GaN motor inverters.
From ultra-wide 18–90V industrial vehicle power modules to high-density telecom brick converters, every Eltrum module is 100% burn-in tested, potted with thermal elastomer, and built to survive severe vibration and humidity.
Global procurement teams are navigating accelerated electrification, stricter EMC directives, and fluctuating raw material supply chains. Here is where the high-reliability power industry is heading and how to align your supply architecture.
Wide Bandgap (WBG) semiconductors are replacing silicon MOSFETs in forward and active-clamp flyback converters. Gallium Nitride (GaN) allows switching frequencies to jump from 150kHz to above 500kHz, reducing transformer volume by 40% while pushing conversion efficiencies beyond 95%.
Modern battery packs experience substantial voltage sag under cold cranking and surge spikes during regenerative braking. The procurement standard has moved from rigid 2:1 ratios (e.g., 36–72V) to flexible 4:1 and 5:1 windows (such as 18–90V DC), consolidating multiple SKUs into a single bill-of-materials.
Tier-1 automation and mobile robotics platforms require active monitoring. Procurement specifications increasingly require isolated PMBus, CAN 2.0B, or RS485 communication interfaces to transmit real-time dielectric leakage status, temperature metrics, and load current directly to the central supervisory PLC.
