Precision-engineered AC/DC rectifiers, hot-swappable telecom power modules, and EV charging units ready for industrial deployment in Sri Lanka.
Addressing Ceylon Electricity Board (CEB) grid characteristics, tropical environmental factors, and high-frequency power switching requirements.
Industrial facility operators across Sri Lanka—spanning the Board of Investment (BOI) Export Processing Zones in Biyagama, Katunayake, and Seethawaka—face unique electrical power quality challenges. The local utility distribution operated by the Ceylon Electricity Board (CEB) and Lanka Electricity Company (LECO) exhibits frequent line-voltage fluctuations, high-amplitude transient spikes caused by monsoon lightning activity, and occasional severe under-voltage sags down to 160V AC during peak demand intervals.
To ensure non-stop operations, our direct-export high-voltage power supplies and AC/DC rectifier modules incorporate ultra-wide input voltage topologies (85V AC to 300V AC single-phase, and 260V AC to 530V AC three-phase). By using Active Power Factor Correction (PFC) circuitry achieving a power factor >0.99 and Total Harmonic Distortion (THD) below 5%, these modules eliminate upstream neutral-line overheating and prevent power factor penalties imposed by local utilities.
Sri Lanka's island climate presents dual ambient threats to heavy power electronics: persistent high relative humidity (often exceeding 85% to 95% RH in Colombo, Galle, and Trincomalee) combined with airborne marine salt-spray corrosion. Standard off-the-shelf power converters rapidly suffer from dendritic silver migration, electrolytic capacitor degradation, and insulation breakdown under these unmitigated conditions.
Our OEM factory production line applies military-grade IPC-CC-830 certified conformal coating across all internal printed circuit board assemblies (PCBAs). Advanced thermal dissipation features—including dual ball-bearing variable speed fans, anodized aluminum heatsinks, and isolated magnetic cores—allow continuous full-load operation at ambient temperatures up to +65°C without premature power derating.
Utilizing zero-voltage switching (ZVS) and zero-current switching (ZCS) resonant converter topologies (LLC half-bridge and full-bridge switchers), our 48V DC telecom rectifiers and 150V-1000V DC EV charging power modules achieve peak conversion efficiencies up to 96.5%. High switching frequencies reduce the physical footprint of transformer cores and passive filter components, resulting in compact 1U and 3U subrack power density that saves critical cabinet space in telecom shelters and EV charging stations throughout Sri Lanka.
Powering mission-critical telecommunications, industrial manufacturing, and electric mobility infrastructure across the island.
As tier-1 Sri Lankan telecom operators (Dialog Axiata, SLT-Mobitel, Airtel Sri Lanka) expand 4G LTE coverage and deploy 5G NR base transceiver stations (BTS), stable -48V DC auxiliary power is vital. Our hot-swappable 2000W to 4000W rectifier modules (such as Vertiv R48-3000e3 and ZHIHENG R4850G platforms) seamlessly integrate into outdoor telecom enclosures, supplying uninterrupted power to optical nodes (FTTH), remote radio units (RRUs), and deep-cycle VRLA/Lithium battery banks.
With Sri Lanka accelerating the adoption of two-wheelers, light commercial EVs, and electric buses along the Southern Expressway (E01), Colombo-Katunayake Expressway (E03), and Central Expressway (E04), robust DC charging hardware is required. Our 20kW, 30kW, and 40kW modular EV power rectifiers deliver wide 150V to 1000V DC output, enabling multi-standard CCS2 and CHAdeMO fast-charging points capable of enduring high-frequency charge cycles in tropical weather.
Sri Lanka's export-oriented apparel accessories, metal electroplating, and jewelry manufacturing sectors require precise current density and low voltage ripple for electroplating and anodizing processes. The POPULACE T30 alternator electroplating rectifier module delivers ultra-low ripple DC output, preventing bath polarization and ensuring uniform micro-thickness plating on brass, copper, and alloy components in Western Province free trade zones.

Key industrial shifts reshaping power conversion technology procurement across the island nation.
In response to volatile national grid fuel costs and tariff restructuring by the Public Utilities Commission of Sri Lanka (PUCSL), industrial facilities in Kurunegala, Kandy, and Hambantota are integrating rooftop solar PV systems with hybrid DC microgrids. Our programmable and DC/DC conversion modules enable direct coupling between solar arrays, battery energy storage systems (BESS), and 48V DC factory automation loads without multiple efficiency-robbing AC/DC power stages.
Sri Lankan telecommunications tower companies (TowerCos) are aggressively phasing out diesel generators in favor of solar power combined with Lithium Iron Phosphate (LiFePO4) energy storage. Modern modular rectifiers require intelligent charging algorithms to handle high charge acceptance rates of lithium chemistries, dynamic load balancing during mains recovery, and remote RS485/CAN bus telemetry integration via SNMP management units.
Built upon rigorous ISO 9001 certified quality controls, offering high reliability and tailored modifications.
Every single power module exported to Sri Lanka undergoes a mandatory full-load thermal burn-in test under elevated temperature conditions in our TÜV-audited factory. Complete component traceability and automated electrical safety checks guarantee zero-defect delivery at Colombo Port.
Because engineering design and assembly occur under one roof, we offer customized output voltage set-points, modified mechanical mounting brackets, specialized wiring harness connectors, and custom firmware parameters adapted specifically to Sri Lankan customer specifications.
We provide full documentation for Sri Lankan Board of Investment (BOI) registered enterprises, including Certificate of Origin (COO), CE/TÜV compliance reports, HS code classification (8504.40), and commercial invoice packs optimized for fast customs clearance at Colombo International Container Terminal (CICT).
Addressing common technical, shipping, and operational inquiries regarding export high-voltage equipment.
Our industrial AC/DC rectifiers incorporate an advanced wide-input AC front-end (typically 85V AC to 300V AC). When grid voltage drops significantly below nominal 230V AC during severe power brownouts, the integrated digital signal processor (DSP) automatically adjusts the pulse-width modulation (PWM) duty cycle, preserving stable 48V DC output without tripping off or transferring load stress to auxiliary batteries.
Yes. Our 20kW, 30kW, and 40kW DC EV charging rectifiers utilize standardized CAN 2.0B communication protocols. They communicate seamlessly with central charging station management systems (CSMS) and localized main controllers (e.g., OCPP 1.6J / 2.0.1 compliance), enabling precise dynamic voltage and current set-point adjustments during vehicle charging sessions.
All power supply units destined for coastal Sri Lanka are treated with dual-layer conformal coating compliant with IPC-CC-830 standards. Heatsinks are constructed from high-grade anodized aluminum, exposed hardware uses stainless steel (SUS304/316), and internal airflow channels are isolated from delicate surface-mount control electronics to minimize salt deposition.
Standard export inventory modules are dispatched within 3 to 7 business days following order confirmation. Air freight to Bandaranaike International Airport (CMB) typically takes 4 to 6 days, while sea freight lines to Port of Colombo take approximately 14 to 21 days depending on container route scheduling.
Yes. Modules like the ZHIHENG R4850G are engineered with precise pin-to-pin backplane dimensions, matching guide rails, and compatible bus communication routines. They can be hot-swapped directly into existing ETP48-200 subrack frames without system power shut-down or modification to subrack wiring.
All brand-new high-voltage and rectifier power modules carry a comprehensive 2-year factory warranty. We offer direct remote engineering support via video call or email for system integration, bus commissioning, and firmware configuration, backed by rapid replacement unit dispatch for critical operational spares.
