Chittagong Lab-Grade Testing Solutions
Pioneering precision regulated power supplies tailored for electronic factories, laboratories, and heavy industrial research divisions in the Chattogram region.
Chittagong Industrial Power Landscape & Challenges
Chittagong (Chattogram), the chief port city and commercial hub of Bangladesh, drives more than 60% of the nation's international trade and industrial output. Hosting massive industrial estates like the Chittagong Export Processing Zone (CEPZ), Karnaphuli Export Processing Zone (KEPZ), and the upcoming Mirsarai Economic Zone (Bangabandhu Sheikh Mujib Shilpa Nagar), the region stands as a powerhouse of heavy fabrication, shipbuilding, steel smelting, textiles, and chemical processing.
However, this rapid industrialization exposes severe deficiencies in the utility grid. Voltage fluctuations, harmonic distortion, frequency drift, and sudden voltage sags are commonplace. For modern CNC manufacturing, precision metallurgical testing, marine electronics calibration, and high-throughput automated assembly lines, these grid instabilities lead to costly downtime, product defects, and component wear.
The APS-53000 Series (5kVA to 500kVA) High-Capacity Programmed AC Power Source acts as the ultimate galvanic buffer. Delivering pure, stabilized, and frequency-configurable AC power, the APS-53000 series isolates sensitive machinery from the local utility grid (BPDB/DESCO) anomalies, guaranteeing absolute operational continuity.

IGBT Pulse-Width Modulation
By using high-frequency Insulated Gate Bipolar Transistor (IGBT) switches, the APS-53000 series synthesizes pure sinusoidal waveforms with extremely low noise margins, preserving downstream equipment integrity.
Galvanic Isolation Design
Built-in multi-tapped isolation transformers ensure that the primary input grid noise cannot propagate to the secondary test output terminals, completely decoupling industrial operations from public grid anomalies.
Dynamic Phase Balancer
Specifically optimized for unbalanced 3-phase loading conditions, making it perfect for multi-stage distribution lines where separate phases experience radically variable power draws.

Localizing the APS-53000 Series for Chittagong's Industrial Environment
Operating electronic instruments in a coastal port city like Chittagong presents significant climate challenges. High ambient relative humidity, averaging above 80% for most of the year, combined with airborne salinity from the Bay of Bengal, accelerates the corrosion of exposed internal circuit boards.
To mitigate these risks, all APS-53000 series units shipped to our Bangladeshi B2B partners incorporate our "Tropicalization Upgrade Package":
- Conformal Coating: All PCB assemblies are triple-coated with high-grade insulating resins to prevent moisture condensation and salt-spray oxidation.
- Enclosed Cooling Channels: High-reliability cooling systems route internal heat dissipation away from critical logic components, utilizing dust-filtered ventilation ports to keep clean air circulating.
- Robust Over-temperature Derating: Engineered to operate reliably at 45°C ambient temperatures without thermal protection trip-outs, which is essential during hot summer months.
Guangzhou Matrix Power Technology ensures efficient logistics processing through Chittagong Port (Chattogram Port Authority). We provide all necessary documentation, including country of origin certifications, CE alignment documents, and comprehensive packaging lists, to expedite customs clearance and logistics routing to your industrial site.
