Products Power Conversion Engineering Proven power platforms customizable for South African telecom, industrial automation, medical devices, and high-wattage consumer hardware.
Addressing grid instability, load shedding stress vectors, compliance frameworks, and high-frequency power switching architectures.
By transitioning from traditional Silicon (Si) MOSFETs to wide-bandgap Gallium Nitride (GaN Fast / GaN Sense ICs), our OEM factory partners achieve up to 3x higher switching frequency. This shrinks magnetic transformer sizes by 45% while driving power conversion efficiency beyond 95.5%.
South African commercial networks face acute voltage spikes and brownouts associated with Eskom load-shedding stage rotations. Our custom OEM designs incorporate bulk electrolytic capacitors with high ripple tolerance and MOV + TVS surge stages capable of absorbing 4kV transients.
Navigating South African compulsory specifications (VC 8055, SANS 62368-1 / IEC 62368-1) requires rigorous CB test reports and EMC conformity. We provide end-to-end documentation packages enabling seamless National Regulator for Compulsory Specifications (NRCS) Letter of Authority (LOA) issuance.
Most off-the-shelf consumer power adapters are engineered for stable 110V or 230V municipal grids with ambient temperatures below 25°C. In South Africa—ranging from coastal humidity in Durban to elevated summer temperatures in Johannesburg (+35°C ambient) paired with daily power switching cycling—off-the-shelf adapters suffer premature thermal degradation, transformer insulation breakdown, and output voltage drift.
Our OEM GaN Charger Factory platforms integrate Active Clamp Flyback (ACF) and PFC + LLC Resonant Topologies paired with potted high-thermal-conductivity compounds. This reduces internal hot-spot temperatures by up to 18°C, guaranteeing an extended operating lifespan even under 24/7 heavy duty operation during load shedding recovery cycles.
Customizing mechanical form factors, pin configurations, and DC cable harnesses for localized equipment deployments.
With widespread adoption of residential and commercial solar inverters (Sunsynk, Deye, Victron) in Gauteng and Western Cape, our multi-voltage DC adapters and high-power GaN fast chargers supply steady auxiliary DC voltage to battery management controllers, IoT monitoring dongles, and smart switches.
In harsh industrial sectors such as Platinum and Gold extraction facilities around Rustenburg and Polokwane, electronics demand ruggedized power supplies. Our custom OEM power bricks feature IP65-rated enclosed potting, vibration resistance, and operating capabilities spanning -40°C to +70°C.
Retail networks, security base stations, and high-speed fiber CPE equipment across South African townships rely on uninterrupted power. We build desktop and wall-mount chargers featuring fast cold-start capability, zero-leakage safety profiles, and integrated South African Type M/C plug profiles.

Over six decades of engineering leadership, precision manufacturing, and rigorous quality assurance pipelines.
We offer full custom enclosure design, complete tooling capabilities, multi-port USB-C/USB-A layout engineering, and private-label branding. From initial CAD modeling to rapid 3D-printed prototyping, custom OEM designs transition to mass tooling in under 35 days.
Every single power unit leaving our production lines undergoes 4 hours of full-load ATE (Automated Test Equipment) dynamic burn-in testing, high-voltage hi-pot insulation safety testing (3kV AC minimum), and automatic ripple-noise spectrum checking.
We source active GaN power semiconductors exclusively from tier-1 suppliers (Navitas, Power Integrations, GaN Systems) combined with Japanese 105°C-rated long-life electrolytic capacitors (Nichicon, Rubycon), ensuring zero counterfeit component risks.
