Providing high-precision linear power sources optimized for electrical engineering laboratories, telecom diagnostic arrays, and electronics repair facilities across Lisbon, Porto, and Braga.
Within high-performance industrial testing, the demand for Linear Power Supplies (LPS) remains robust despite the ubiquity of Switch-Mode Power Supplies (SMPS). While SMPS designs excel in size and efficiency, they are inherently prone to high-frequency electromagnetic interference (EMI) and ripple noise. For sensitive laboratory testing, semiconductor calibration, and RF communication systems, only the clean, ripple-free performance of linear topology is acceptable.
Across the European Union—specifically in tech-forward zones like Iberia—manufacturing sectors are undergoing rapid digitalization. High-accuracy sensors, medical imaging instrumentation, and aerospace testbeds rely on linear DC sources to achieve measurement repeatabilities down to the microvolt level. This creates a critical supply-chain requirement for high-reliability, long-lasting linear modules.
Portugal is establishing itself as a specialized engineering and automotive electronics powerhouse in Southwestern Europe. High-tech manufacturing regions such as the Setúbal Automotive Peninsula (centered around AutoEuropa and its component supply cluster), the Porto Digital Region, and the Minho Electronics Valley (Braga/Guimarães) require specialized test equipment to guarantee stringent product quality controls.
Key sectors driving linear power supply integration in Portugal include:

For Portuguese engineers designing critical electronic equipment, choosing the correct supply topology can determine success or failure in meeting European electromagnetic compliance (EMC) regulations. The table below outlines why linear regulation remains indispensable for research and sensitive medical/audio electronics:
| Performance Parameter | MYAMI Linear Power Supplies (LPS) | Standard Switching Power Supplies (SMPS) |
|---|---|---|
| Ripple Voltage & Noise | < 0.5mV RMS (Typical) | 10mV - 100mV RMS (High-frequency noise spikes) |
| Transient Recovery Time | < 50 microseconds | 1 to 5 milliseconds |
| Electromagnetic interference (EMI) | Virtually zero EMI emissions | Significant EMI requiring heavy external filtering |
| Efficiency (Full Load) | 35% - 50% (Dissipated as heat) | 80% - 95% |
Any laboratory or industrial facility importing power conversion equipment into Portugal must meet EU directives. MYAMI ensures all linear power supplies meet these compliance metrics:

The development of linear power supplies is shifting from simple analog control to smart digital ecosystems. As manufacturing and test processes require higher levels of automation, linear power supplies must evolve. Here is MYAMI's design trajectory:
We are incorporating Ethernet and Wi-Fi modules into our programmable lineups. This allows test floor managers in Lisbon to remotely monitor energy usage and detect thermal anomalies over Modbus TCP networks.
By pairing a highly efficient SMPS pre-regulator with a precision linear output pass element, we achieve up to 70% efficiency while maintaining ultra-low noise levels under 1mV RMS.
Using advanced heat pipe technology and speed-controlled fans, we have reduced module footprints by 25% while maintaining safe operating temperatures under continuous load.
