Engineered for precise power regulation, high efficiency, and severe operational resilience across OEM platforms.
As the Seoul Metropolitan Area advances its initiative to solidify its status as a global hub for smart city transportation, 5G/6G communications, and next-generation industrial automation, the demand for compact, high-efficiency, and thermally robust power conversion components has escalated. Among standard board-mounted power architectures, the Quarter Brick DC-DC converter (2.28 x 1.45 inches / 57.9 x 36.8 mm) has emerged as the definitive form factor for systems engineers operating within tight volumetric constraints.
System designers in key technology centers such as Pangyo Techno Valley, Magok Industrial Complex, and Digital Media City (DMC) face complex trade-offs: balancing high power outputs (ranging from 50W to over 500W in quarter-brick packages) with severe thermal dissipation constraints, stringent electromagnetic compatibility (EMC) regulations, and dynamic voltage fluctuations inherent to modern industrial grids and e-Mobility battery banks.
NetPower, as an established original equipment manufacturer (OEM) and custom supplier of board-mounted isolated DC-DC converters, non-isolated Point-of-Load (POL) modules, and e-Mobility power conversion systems, provides tailored quarter-brick solutions engineered specifically to address these challenges. By incorporating advanced soft-switching topologies, planar transformers, and thermal potting technologies, our OEM quarter-brick series provides the high information gain and engineering reliability mandatory for critical mission deployments across South Korea.

Configurable input stages accommodating telecom -48V rails, industrial 24V bus lines, rail transit 110V networks, and high-voltage EV auxiliary systems up to 650VDC.
Multi-option thermal design including open-frame air-cooled bricks, baseplate-cooled encapsulated modules, and direct-conduction liquid-cooled cold plate integration.
Tailored power solutions driving critical urban infrastructure, eco-friendly transit, and advanced automation.
In support of the Seoul Metropolitan Government’s zero-emission public transit mandates, our 3.3kW On-Board Chargers (OBC) and high-power OEM quarter-brick DC-DC converters are deployed in electric buses, delivery trucks, and specialty municipal vehicles across the Incheon-Seoul logistics corridor.
These units convert high-voltage battery pack power down to 12V/24V auxiliary power for steering, safety lights, HVAC control, and CAN bus telemetry systems under harsh vibration conditions.
South Korea’s rapid rollout of cloud computing, AI server clusters, and 5G network towers demands highly reliable intermediate bus converters (IBC). Operating from a standard -48V nominal input, our quarter-brick modules convert voltage down to 12V or 5V intermediate rails with efficiency ratings up to 96%.
This thermal performance minimizes HVAC cooling energy demands within tight server rooms in Pangyo Silicon Park.
Industrial smart factories in Gyeonggi-do utilize automated guided vehicles (AGVs) and autonomous mobile robots (AMRs) requiring robust, low-noise power supplies. Our encapsulated, IP67-rated power modules deliver stable DC output despite mechanical shock, dust exposure, and high ambient temperatures.
Custom output trimming allows precise matching with specialized lithium battery chemistries (LiFePO4 and NCM).
Under Google's Search Quality Rater Guidelines, establishing **Experience, Expertise, Authoritativeness, and Trustworthiness (E-E-A-T)** requires transparent proof of manufacturing rigor, testing protocols, and operational history. NetPower operates under a comprehensive quality management system designed to guarantee zero-defect performance across millions of deployed power converters worldwide.
Prior to prototype fabrication, every quarter-brick circuit undergoes rigorous worst-case circuit analysis (WCCA), stress derating evaluation, and finite element thermal modeling to ensure components operate within 60-70% of maximum ratings.
Highly Accelerated Life Testing (HALT) and Stress Screening (HASS) subject modules to rapid thermal cycling (-50°C to +125°C) and multi-axis vibration to uncover potential latent defects long before customer delivery.
Every single unit shipped to customers in South Korea undergoes automated optical inspection (AOI), high-potential isolation testing, burn-in screening under full load, and automated test equipment (ATE) parameter verification.
NetPower’s production facilities maintain strict compliance with international quality standards, ensuring full material lot traceability for tier-1 automotive and industrial clients. Whether supplying standard off-the-shelf bricks or co-engineering full-custom power conversion sub-assemblies, NetPower power engineers collaborate directly with OEM clients from schematic design to mass production.
Direct engineering answers to common procurement, integration, and compliance questions.
Whether you need standard DOSA-compliant bricks, customized high-voltage DC-DC converters, or integrated 3.3kW On-Board Chargers for your Seoul-based platform, NetPower delivers engineered performance and field-proven reliability.
