Explore our engineering-grade DUAL-series SMPS products, optimized for balanced load distributions and industrial-grade automation platforms.
Modern industrial architectures demand highly specialized electrical infrastructure. Unlike single-rail power units, a dual-output switching power supply (SMPS) must manage two independent voltage outputs (e.g., 5V/12V, 12V/24V) within a single mechanical footprint. This dual-output capability is critical in systems where control units (such as PLCs or microprocessors running on 5V or 12V) operate alongside heavy actuation components (such as relays, DC motors, or solenoid valves running on 24V).
NVVV Electric Technology addresses the core challenge of dual-output topologies: cross-regulation. When the load on one rail swings from 10% to 100%, it typically induces magnetic flux variations that affect the voltage stability of the secondary rail. Our engineers minimize this through optimized coupled-inductor topologies and precise multi-winding transformer designs, ensuring both rails maintain load regulation parameters within +/- 5% tolerances.
Furthermore, electromagnetic interference (EMI) is actively suppressed using built-in EMI filters conforming to FCC Class A/B and EN55022 parameters. Each switching circuit incorporates active soft-start features to prevent input surge currents from destabilizing upstream supply grids, protecting the dual switch power supply and the overall electrical network.
How NVVV is pioneering the next phase of switching power supply technology through advanced materials and digital control integration.
We are transitioning our mid-to-high wattage dual switch power supplies to Wide Bandgap (WBG) Gallium Nitride power transistors. GaN semiconductors reduce switching losses by up to 60%, allowing our units to operate at higher switching frequencies (over 150kHz) while reducing physical sizes by 30% and boosting overall efficiency.
Next-generation NVVV designs will feature integrated microcontrollers supporting PMBus or Modbus protocols. This allows connected industrial automation systems to read real-time diagnostics (such as temperature, current draw, and ripple voltage), facilitating predictive maintenance and lowering system downtime.
In response to global eco-directives such as ErP Lot 6, our engineering team is integrating smart burst-mode control chips. When load demand falls below a threshold, the power supply enters a sleep/burst state, lowering standby power draw to under 0.5 Watts.
Deploying dual-rail switching power supplies across challenging modern infrastructure environments.
Providing independent power rails for control chips (12V/5V) and actuator coils/servo motors (24V). Prevents inductive spikes from interfering with microcontroller cycles, maintaining zero-error communication paths in PLC racks.
