AMED Switching Power Supplies — what are their applications?

Aimtec AMED series switching power supplies feature standardized dimensions that allow for DIN rail mounting. This design concept is closely linked to the target areas of application for these power supplies, which are widely used in sectors such as:

• building automation,
• industry (process and machine control, robotics, industrial automation),
• power engineering,
• telecommunications and communication systems,
• surveillance systems.
   

By efficiently converting alternating current (AC) to stable direct current (DC), AMED power supplies provide an excellent solution for demanding industrial and infrastructure environments.

AMED by Aimtec — solution availability

Aimtec’s AMED power supplies are available in a variety of models, with output power ranging from 10W to 480W, catering to diverse industrial needs. For instance, the AMED20-GY series offers:

AMED20-12SGY:

• Output power: 20W
• Output voltage: 12V
• Maximum output current: 1.6A
• Efficiency: 80%
   

AMED20-24SGY:

• Output power: 24W
• Output voltage: 24V
• Maximum output current: 1A
   

Models in the series are marked with specific letters to indicate additional capabilities:

• W models: Designed for operation in two-phase AC power systems.
• T models: Support three-phase AC input, making them suitable for higher-power applications.
   

The AMED20-12SGY power supply offers an efficiency level of 80%

Among the available power supplies, there are models marked with the letter W, which enable operation in two-phase AC power systems. Models marked with the letter T, on the other hand, provide three-phase input.

Efficiency of AMED Power Supplies by Aimtec

AMED power supplies by Aimtec are designed with efficiency, reliability, and safety in mind, even in challenging environmental conditions. The proper conversion of AC input voltage to output voltage is ensured by well-coordinated and cooperating components, including:

• an AC input rectifier that converts AC voltage into pulsating DC voltage,
• a smoothing capacitor that reduces the ripple in the rectified DC voltage,
• a high-frequency switch (MOSFET) that switches DC voltage at high frequency, allowing for efficient voltage regulation,
• a PWM controller (Pulse Width Modulator) that regulates the MOSFET duty cycle by controlling the output voltage,
• a transformer that transfers and isolates the signal while adjusting the voltage level,
• an output rectifier and filter — this system converts the voltage back to DC and filters out high frequencies, delivering a stable, noise-free output voltage.
   

Aimtec places great emphasis on low ripple and noise in the output, minimizing interference with sensitive electronic devices.

Protections and Additional Features Used in AMED Power Supplies

In addition to AC/DC conversion, Aimtec’s DIN rail power supplies offer a range of advanced features that enhance performance and provide system protection:

• Overload and short-circuit protection: Electronic circuits detect and limit excessive current draw, protecting both the power supply and the connected devices. Intelligent overcurrent systems ensure a quick and reliable response in the event of overloads.
• Overvoltage protection: The devices are protected against damage caused by overvoltage, which refers to voltage levels exceeding the rated output voltage.
• Inrush current limitation: The circuit reduces the initial surge of current during power-up, protecting downstream components in the circuit. Limiting inrush current minimizes the strain on devices connected to the power supply during start-up.
• Over-temperature protection: When a temperature rise beyond the permissible level is detected, the device shuts down. Once the temperature returns below the critical threshold, the power supply automatically resumes operation.
   

DIN rail-mounted power supplies provide a reliable, efficient, and compact solution for powering industrial and infrastructure equipment. Understanding their key features, advantages, and selection criteria ensures the optimal performance and long service life in dedicated applications. With their robust design, efficient performance, and advanced protective features, they are built to meet the demands of modern systems.
