Voltmat Power
Highly efficient AC-to-DC converters built for electrical grid compliance in Colombo, Gampaha, and global industrial hubs.
Sri Lanka's industrial landscape is experiencing a fast-tracked phase of modernization. Under the initiative of economic zones such as the Katunayake Free Trade Zone, Biyagama Export Processing Zone, and the emerging Port City Colombo, modern factories require consistent and precise electrical power infrastructure.
However, industrial operations in Sri Lanka face distinct electrical issues, including frequent voltage sags, power grid instability, and high humidity levels typical of a tropical maritime environment. Precision industries—such as high-end apparel textile mills, food processing plants, telecommunication grid stations, and electronic components assembly lines—cannot afford power interruptions or unstable DC outputs. A minor shift in supply voltage can cause hardware deterioration, control system resets, or complete production line downtime.
Our OEM customized DC power supplies are specifically designed to address these concerns. Engineered with integrated protective circuits and robust thermal architectures, they function reliably within Sri Lanka's municipal grids, ensuring that modern automated lines operate continuously without power fluctuations.
Providing optimal power solutions for Sri Lanka's key industrial, maritime, and communication infrastructure.
With Sri Lanka's progressive shift toward electric mobility, especially light electric vehicles (LEVs) and e-rickshaws, the demand for highly efficient high-power battery chargers is rising. Our 20KW+ DC supplies provide the constant-current, constant-voltage profiles required for industrial battery testing and fleet charging networks.
The Port of Colombo is a crucial shipping hub in the Indian Ocean. Specialized power equipment running in ports must endure heavy sea air salinity and high humidity. Our customized DC units with conformal coatings prevent galvanic corrosion and ensure continuous operation for crane control and shipyard electroplating.
From Jaffna to Galle, keeping cell towers and rural digital switches operational requires highly stable power converters. The DC power systems we export are engineered with smart telecom backup capabilities, preventing diagnostic disruptions and keeping communication networks active.
We do not deliver generic products. Standard systems are rarely optimal for the specific environmental demands of the South Asian sub-continent. Our engineering process incorporates modifications specifically suited to local conditions:
Our solutions feature active Power Factor Correction (PFC) modules that improve efficiency up to 89%, reducing reactive power consumption and lowering operational electricity costs for factories in Sri Lanka.
Every unit undergoes two rounds of computer and manual testing in our 10,000㎡ facility to maintain our 99.9% qualification rate.

Providing industrial facilities in Sri Lanka with reliable, high-efficiency equipment for electrical testing, anodizing, and laboratory testing.
Operating from our 10,000-square-meter facility in Shanghai, we leverage local component supply networks to offer responsive OEM customization. Over 15 years in high-power regulation systems, our production line handles raw metal cutting, transformer winding, assembly, and automated testing on-site.
For exports to Sri Lanka, we protect each unit against maritime transport conditions using a multi-layer packaging process:
Located near the Port of Shanghai, we arrange freight shipments to Colombo Port with routine delivery schedules, assisting with custom documentation to ensure clear import logistics.
Technical answers for electrical engineers, system integrators, and procurement officers in Sri Lanka.
Our standard models support three-phase input configurations (380V/400V/415V AC ±15%, 50Hz/60Hz). For Sri Lankan industrial grids, we custom-configure the transformer and power stage to ensure continuous regulation even during common voltage fluctuations.
We apply a thick layer of high-grade insulating conformal coating to all printed circuit boards (PCBs). Critical power modules are sealed, and external enclosures are finished with anti-corrosion powder coatings to handle coastal air conditions.
Yes. Our bench and industrial power supplies are adjustable across their full scale (0V to maximum voltage, and 0A to maximum current). They support manual adjustment via front-panel encoders or remote control through RS485/Modbus RTU interfaces.
Standard orders are completed in 15 to 20 business days, while custom OEM designs require 25 to 30 days. Shipping from Shanghai Port to Colombo Port via direct sea routes usually takes 14 to 18 days.
All exported models include a 1-year warranty. We supply replacement parts and detailed maintenance schematics. Technical assistance is available online via video or remote diagnosis from our Shanghai engineering team.
