LCB100L Power Supplies - External/Internal (Off-Board)

The LCB100L application field and working principle is an important element of AC DC converters. With the continuous development of industrial automation, the demand of stable power source is increasing. For many large industrial power supplies, AC DC converters are used to provide power for various applications.

The LCB100L is an ac dc converter commonly used in industrial applications. It is a high-efficiency, factory-price, low-noise, and reliable product made by a major Italian manufacturer, applicable to industrial control power supplies for robotics, elevators, air conditioning, medical equipment, and electric lamps, etc. It can convert three-phase AC voltage to DC voltage with the working principle of PWM and PFM signaling.

The LCB100L is mainly composed of rectifier, filter, power supply circuit and micro-controller. The rectifier converts AC power to DC. The filter circuit filters the ripple in the AC power converted by the rectifier and output DC power. The power supply circuit stabilizes the output voltage of the filter circuit, and the controller controls the output voltage of the power supply circuit to meet the requirements of the device in use.

The working principle of LCB100L is based on Pulse Width Modulation (PWM) and Pulse Frequency Modulation (PFM) signaling. The power supply circuit and the controller are connected to each other, where the circuit receives the signals of the controller to adjust the voltage. When the input power of the rectifier exceeds the output voltage of the power supply circuit, the controller will detect the voltage. The controller will then command the circuit to increase the width of the voltage pulse so that more power is available when the voltage exceeds the output voltage of the power supply circuit . Meanwhile, the controller will detect the frequency of power supply, and when the frequency increases, the controller will command the circuit to reduce the width of the voltage pulse.

The LCB100L can provide continuous, stable, and low-noise DC voltage. Its wide range input voltage, high-efficiency, low-noise, factory price, and reliability make it an ideal choice for industrial power supplies. In addition, its compact size and light weight make it suitable for many industrial applications where space is limited.
