Power supplies for general use replace the batteries. They cooperate with a variety of mobile devices such as radios, television sets, CD, DVD and MP3 players, phones and monitors, tourist refrigerators. Power supplies also support musical instruments (including keyboards), medical and measuring instruments, aerial amplifiers and headphone antenna, illuminated and computer equipment (laptops, printers, peripherals). They’re an indispensable piece of cash registers, scales and bar code readers. We will meet them also in the automotive industry as a power source of an increasing number of commercially available mobile devices. From the beginning, our company places particular emphasis on the highest quality of our products so that users can rely on many years of trouble-free operation of our devices.
