AC DC converters are electrical devices used to convert electricity from alternating current (AC) to direct current (DC). The AC DC converter type LCL150PS15 is an off-line ac/dc switching power supply that contains a control circuit, inrush current limitation, active power factor correction, overload protection, short circuit protection, over voltage protection, input surge protection, thermal protection, and other protection functions. It also meets UL, CSA, TUV, FCC, CB and other safety and EMC requirements.

Application Fields

LCL150PS15 AC DC converters are primarily used for industrial automation systems, with excellent performance and high reliability. This AC DC converter provides power to a vast range of industrial products, such as: PLCs, drives, servo systems, communication and network equipment, UPS’s, distributed control systems, field controllers, semiconductor equipment, laser marking systems, 3D printing equipments, etc.

The size of this AC DC converter is also very compact, with a profile of only 350mm (W) by 95mm (H) by 160mm (D). Moreover, it has a wide working temperature range of -40°C to +70°C and a high efficiency up to 94%. This makes it fit for applications where saving space and low power dissipation is a concern.

Working Principle

In order to understand the working principle of the LCL150PS15 AC DC converter, we must first get familiar with what an AC to DC converter is made up of. This converter is comprised of an AC/DC rectifier, an EMI filter, an input voltage control, an output voltage control, and a magnetic circuit with a transformer in order to provide isolation.

The electric rectifier acts as the main power factor correction module by rectifying input 230VAC power to a DC voltage. This rectified voltage is then applied to the magnetic circuit, where it is converted to the desired output DC voltage by passing it through the transformer. The output transformer is made up of an effective magnetic core surrounded by a winding. In this process, the generated magnetic field is used to control the amplitude of the AC input voltage, and therefore the output DC voltage.

The EMI filter works as a shield from high frequency noise interference in the output voltage. It has an important role of making sure that the output voltage is safe and reliable. The input voltage control works together with the rectifier in order to ensure the power fed to the magnetic circuit is within a safe range. Finally, the output voltage control is responsible for monitoring and adjusting the output DC voltage to its desired level.

This is the basic idea of how the LCL150PS15 AC DC converter works. It can make the output voltage more stable and reliable compared with other products. This AC/DC converter type is becoming more and more popular in the modern industrial automation applications.
