Advanced high-density power modules, ruggedized online UPS platforms, and DC-DC conversion architectures for Sri Lanka's telecom, railway, energy, and automated industrial sectors.
In high-density industrial electronics, the standard DOSA (Distributed-power Open Standards Alliance) Quarter-Brick form factor (dimensioned at 2.28 x 1.45 x 0.50 inches / 57.9 x 36.8 x 12.7 mm) represents the critical backbone for intermediate bus architectures (IBA) and point-of-load (POL) power distribution. As a leading manufacturer and exporter supplying the Sri Lanka market, our quarter-brick DC-DC converters overcome the legacy thermal dissipation bottlenecks that historically plagued conventional diode-rectified power modules.
Traditional DC-DC converter modules rely on Schottky barrier diodes on the secondary output side. At high current loads (e.g., 30A to 60A output), the forward voltage drop ($V_f$) across diode junctions creates extreme power dissipation ($P_{loss} = I_{out} \times V_f$), generating massive heat loads that require bulky external heatsinks or aggressive forced-air cooling.
Our quarter-brick converter series replaces lossy output diodes with actively driven, ultra-low $R_{DS(on)}$ N-channel MOSFETs operating as Synchronous Rectifiers. Paired with a proprietary multi-stage resonant converter topology, this switching methodology reduces secondary conduction losses by up to 75%.
Consider a 240W Quarter-Brick Converter operating at 12V / 20A output:
Sri Lanka's strategic geographical positioning in the Indian Ocean has triggered rapid modernization across maritime logistics, telecommunications networks, renewable energy grids, and specialized manufacturing export zones. Supplying high-reliability quarter-brick power modules into Sri Lanka requires localized engineering adaptations capable of weathering harsh tropical and electrical conditions.
Our quarter-brick power modules and ruggedized power systems are deployed across critical national projects and free trade zones throughout the island:
Powering rugged ship-to-shore crane automation, automated guided vehicles (AGVs), marine navigation buoys, and vessel AIS transponders. Baseplate-cooled quarter-brick units withstand salty ocean winds and high relative humidity (up to 95%).
Supplying remote radio units (RRU) and telecom base stations (BTS) operated by major Sri Lankan telecom providers. Quarter-bricks step down nominal -48VDC telco buses to tightly regulated 3.3V, 5V, or 12V core logic boards.
Export processing zones in Biyagama, Katunayake, and Seethawaka rely heavily on automated computerized knitting and cutting machinery. Our isolated DC-DC bricks protect delicate PLC controllers from utility voltage spikes.
Supporting Sri Lanka's 'Battle for Solar Energy' initiative. Quarter-brick modules provide control board power within high-voltage solar string inverters and decentralized battery energy storage systems.
Purchasing power conversion hardware for multi-year OEM deployments requires absolute confidence in supplier capabilities, long-term component availability, and stringent quality control standards. As an established global manufacturer, our operational infrastructure is built around total process transparency.
Our state-of-the-art manufacturing facilities utilize automated surface-mount technology (SMT) lines with 3D Automated Optical Inspection (AOI) and 3D X-ray inspection to guarantee 100% solder joint integrity on planar magnetics.
To resist Sri Lanka's high relative humidity, coastal salt spray, and atmospheric fungal growth, all exported quarter-brick modules feature optional military-grade acrylic or silicone conformal coating meeting MIL-I-46058C.
We mitigate end-of-life (EOL) risks for long-lifecycle defense, rail, and utility programs. We offer form-fit-function replacement guarantees and maintain active raw component strategic buffer stock for minimum 15-year availability.
Addressing common technical, environmental, and logistical queries from electrical engineers and procurement specialists in Sri Lanka.
Our quarter-brick modules are engineered specifically for high thermal stress environments. Thanks to synchronous rectification delivering up to 96% efficiency, internal heat dissipation is minimized. Featuring an integrated aluminum baseplate, heat can be directly conducted into your equipment's outer chassis or a cold-plate heat sink. When operated with baseplate cooling, our converters deliver 100% full-rated output power up to 85°C baseplate temperature without derating, perfectly suited for unconditioned sealed enclosures in Sri Lanka's tropical climate.
Yes. Auxiliary DC buses powered by front-end AC-DC rectifiers often experience severe transient spikes due to utility grid switching or lightning strikes during monsoon seasons. Our quarter-brick converters incorporate high peak-voltage transient protection (up to 100V for 100ms on 48V input models) and high input-to-output galvanic isolation rated at 2,250VDC. When paired with our transient suppressor EMI filter modules, the combined architecture fully satisfies MIL-STD-1275, MIL-STD-704, and EN 50155 surge immunity specifications.
Absolutely. All our quarter-brick DC-DC converters adhere strictly to industry-standard DOSA footprint dimensions (57.9 x 36.8 mm) and standardized pinouts. Whether your system currently utilizes quarter-brick modules from Vicor, SynQor, Delta, Artemis, or TDK-Lambda, our engineering team provides direct form-fit-function cross-reference mapping, allowing seamless drop-in replacements with improved thermal margins and lower unit costs.
Every export shipment to Sri Lanka includes comprehensive technical documentation, including Certificates of Conformance (CoC), full Factory Acceptance Test (FAT) data sheets, RoHS 3 compliance certificates, REACH documentation, and CE/UL safety agency reports. For military or government projects (such as Sri Lanka Navy or Railway tenders), we can supply complete MTBF calculation reports per Telcordia SR-332 / MIL-HDBK-217F and thermal derating curves.
Standard catalog quarter-brick models are maintained in core buffer stock with quick-ship sample dispatch within 48 to 72 hours. OEM volume production orders typically carry a 4-to-6 week lead time. We ship directly to Bandaranaike International Airport (CMB) via expedited air freight (DHL/FedEx/Air Cargo) or sea freight to Colombo Port. Our international trade compliance team handles all customs HS code classification (typically HS 8504.40) to ensure frictionless Sri Lanka Customs clearance.
