AC/DC genset

Stable and safe power supply for electronics and industry

AC/DC power supplies are used to convert alternating current (AC) voltage from the mains into stable direct current (DC) voltage to power electronics, control systems and industrial applications. A reliable power supply is essential for the reliability, performance and longevity of electrical systems.

Swelex offers a wide range of AC/DC generators for industrial, commercial and demanding environments - from compact, built-in generators to powerful solutions for cabinets, machines and system installations.

Power supply for the railway industry

AC/DC generators are a key component of modern railway technology. They convert alternating current from the catenary or supply system into stable direct current for the train's electronic functions, such as door controls, lighting, information systems and air conditioning.

High efficiency and resistance to voltage fluctuations ensure reliable operation even under high loads and demanding environmental conditions - an important part of energy-efficient and safe train operation.

FAQ - Frequently asked questions

What is the difference between a power supply unit and an AC/DC unit?

  • The terms are often used interchangeably. AC/DC power supplies clearly describe the function - conversion from AC to DC voltage.

 

When are redundant AC/DC generators needed?

  • In applications where downtime is not acceptable, such as in industry, energy, telecoms or safety-critical systems.

 

Can AC/DC generators be used in harsh environments?

  • Yes, there are industrial-grade units designed for high temperatures, vibrations and harsh operating environments.

 

Does Swelex help with selection and specialised solutions?

  • Yes, we offer both standard units and customised solutions based on application requirements.
