ELITE POWER
Premium OEM and ODM solutions serving critical communications, automation, and commercial networks in Colombo, Gampaha, and Hambantota.
Sri Lanka operates on a nominal 230V AC grid voltage at 50Hz. However, rapid commercialization in Free Trade Zones (FTZs) and seasonal tropical monsoons introduce substantial grid challenges:
To counter these challenges, our AC/DC adapters are built with heavy-duty input transient protection (VDRs and gas tube arrestors), high-temp primary capacitors rated at 105°C, and double-sided conformal coatings.
How our engineered units compare to standard consumer adapters under local Sri Lankan field conditions.
| Feature Parameter | Standard Units | Our Sri Lanka Grade |
|---|---|---|
| Input Voltage Range | 100-240V AC | 85V-265V AC (Wide Tolerant) |
| Surge Immunity | 1.0 kV (L-N) | 4.0 kV Differential / 6.0 kV Common |
| PCB Conformal Coating | None (Bare Board) | Acrylic/Silicone Anti-Humidity Shielding |
| MTBF Rating | 20,000 Hours | >100,000 Hours (MIL-HDBK-217F) |

Years Engineering Experience
Aligning with global efficiency regulations and next-gen material developments to deliver future-proof power systems.
Transitioning our 65W to 240W adapters from traditional silicon MOSFETs to Gallium Nitride power stages. This modification improves efficiency up to 94%, drastically minimizes heat emission, and shrinks form factors by 35%.
Next-gen desktop chargers will offer real-time power monitoring interfaces (I2C or SMBus protocol) that allow connected enterprise systems to check real-time current, temperature, and degradation indicators.
Striving for ultra-low standby power configurations (< 0.075W under no-load states). Our designs adhere strictly to the stringent EU CoC Tier 2 and US DoE Level VI standards, minimizing waste heat and local electricity costs.
Supplying essential sectors with high-reliability power units designed for minimal maintenance overhead.
Sri Lanka's rural mobile networks and microwave links demand extremely low-noise power input. Our 200W battery charging systems feature filtered ripples below 100mVp-p, preserving signal integrity even under volatile temperature variations in dry and wet zones.
From tea sorting instrumentation to textile loom sensors in Katunayake EPZ, our DIN-Rail power supplies and high-quality open frame units feature built-in auto-recovery over-current, over-voltage, and short-circuit protections.
Providing clinical equipment and hospital terminals in Colombo with 2xMOPP (Means of Patient Protection) safety isolation. Features extremely low leakage current (< 100µA) compliant with IEC 60601-1 safety margins.
Flicker-free high-efficiency constant-current drivers designed with active PFC (Power Factor Correction > 0.95), optimizing power consumption across municipal grids and private hospitality infrastructure.
Leveraging our advanced factories based in Dongguan and Shenzhen, we offer direct access to high-efficiency production lines that minimize cost margins while maintaining rigorous quality control:
Typical shipping timeline from our Dongguan/Shenzhen factory floor to Colombo Port (Sri Lanka):
Phase 1: Design Validation (3-5 Days)
Schematic generation, PCB layout layout confirmation, thermal calculation models.
Phase 2: Production & Test (15-20 Days)
SMT placement, manual assembly, aging testing, packaging design confirmation.
Phase 3: Ocean Shipping to Colombo (10-14 Days)
Loading at Shenzhen/Guangzhou ports, transit through Indian Ocean shipping corridors.
Comprehensive options featuring global power certifications and custom plug types tailored for Sri Lankan requirements.
Importing electronics into Sri Lanka requires adherence to local importation standards and international electrical safety benchmarks. All of our production models undergo standard design testing to confirm conformity:
1. Safety Approvals (CE, CB, UL, GS, FCC)
Our power adapters meet IEC/EN 62368-1 for audio/video and IT equipment, and IEC 60601-1 for medical device architectures.
2. SLSI Compatibility
We customize high-power adapters and desktop chargers with Sri Lankan-type G fused square pins (BS 1363 standard) or optional D-type round pin configurations, eliminating the reliance on low-quality third-party outlet converters.
3. Eco & ROHS Directives
We monitor component sourcing to restrict hazardous substances, ensuring RoHS and REACH compliance to simplify customs documentation at Colombo ports.
How our products resist degradation in maritime and high-precipitation zones:
Expert engineering insights and logistical details regarding custom imports to Sri Lanka.
For standard desktop adapters and wall-plug-in units, our minimum order quantity starts at 1,000 units. For specialized industrial open frame supplies, heavy-duty chargers, or customized medical power supplies, MOQs are negotiable depending on configuration options and component availability. Please contact us for specialized project rates.
Our engineering team designs AC/DC switching topologies with wide universal input ranges (85V to 264V AC). We implement overvoltage protection (OVP) and robust input filters, using premium metal oxide varistors (MOVs) to clamp grid voltage spikes before they reach sensitive downstream load components.
Yes, absolutely. We provide a complete range of DC output options. This includes standard 5.5x2.1mm, 5.5x2.5mm barrel jacks, right-angle configurations, USB Type-C Power Delivery, lockable aviation plugs, and custom wire harness configurations tailored to your system's interface.
