AC DC Converters

AC DC Converters are electrical devices designed to convert alternating current (AC) to direct current (DC). AC/DC adapters use a combination of rectifier circuits, power transformers and voltage regulators to provide a safe, reliable and cost-effective method of transforming AC power to DC power.The LDA300W-3-S is a single-phase AC/DC converter popularly used in industrial and commercial applications. It is capable of converting 85-265Vac to 24Vdc output. It is also a static switch, allowing the user to switch between two different DC voltage sources, making the converter suitable for backup supply and UPS applications.

Working Principle

The basic components of the LDA300W-3-S converter are the rectifier circuit, the transformer, the voltage regulator and the switch-over contacts. The rectifier circuit changes AC power to unregulated DC power by passing it through a diode bridge. The rectified power is then fed into a power transformer to reduce or increase the voltage to the desired output voltage.Next, the power is fed to the voltage regulator, which controls the output voltage of the converter in order to maintain sufficient power to the load. Finally, the switch-over contacts allow the user to manually switch between two different DC voltage sources, giving redundancy in power supply applications.

Application Field

The LDA300W-3-S AC/DC converter is suitable for use in applications such as backup power systems, solar systems, telecommunications, machine tooling, medical equipment, UPS systems, transportation systems, and consumer electronics. It is efficient and reliable and features an isolated case for safety. In addition, it is designed to run continuously in ambient temperatures ranging from -20℃ to +60℃ and is also designed to meet the stringent electromagnetic compatibility (EMC) requirements of IEC 60950, EN61000-3-2/-3-3/-4-2/-4-4 and other related regulations. As such, the LDA300W-3-S is one of the most reliable, cost-effective and widely used single-phase AC/DC converters in the market today. It is suitable for use in a variety of applications and provides a safe, reliable and consistent current transform from AC to DC power.
