AC DC converters are essential electrical components used to convert alternating current (AC) into direct current (DC). They are used in many applications, from industrial controls to vehicle charging systems. The KRS25F-12 is a common type of AC DC converter that is widely used and has good performance characteristics. This article will examine the application field and working principle of the KRS25F-12.The KRS25F-12 is a general-purpose AC DC converter that can be used for a variety of applications, including the control of motors, pumps, fans, and other mechanical equipment. It is also ideal for powering electronic components such as relays and solenoids. The KRS25F-12 has a wide input voltage range (from 90 to 250 VAC) and a substantial output power range (up to 2kW). It also features overvoltage and overload protection, making it an ideal choice for many applications.The KRS25F-12 works by first rectifying the AC input voltage into DC voltage. This is done by means of a diode bridge rectifier circuit composed of four diodes. The rectified DC voltage is then smoothed out by a large capacitor (or a group of capacitors in series), which essentially acts as a reservoir of energy. The smoothed DC voltage is then used to drive a switching transistor that is configured in a half-bridge configuration. The transistor is driven by a pulse-width modulation (PWM) signal, and its switching will cause the output voltage to be switched between the input and ground. In this way, the output voltage is regulated to the desired level.The KRS25F-12 is a popular choice for applications where a reliable, compact, and efficient AC DC converter is required. Its wide input voltage range, good output power range, and protection features make it well-suited to a variety of applications. Overall, it is a high-performing and reliable AC DC converter.
