AC-DC converter is a device which transfers currents from AC to DC, allowing for a constant DC output regardless of the varying input AC power. AC-DC converter usually consists of three parts, namely rectifier, filter, and regulator. SMC500PS24-C is a typical AC-DC converter, which can be used in various application fields.

Application field

SMC500PS24-C converter is mainly used in industrial control, such as robots, elevators, printing equipment, medical equipment, computer controllers, communication systems, power plant monitoring systems and servo systems. It can also be used in aerospace applications, electric vehicle charging systems and other harsh electromechanical environment. Furthermore, its wide input voltage range can be used in conjunction with a variety of other power supplies.

Working Principle

The SMC500PS24-C converters employ two stages to transfer AC voltage to DC voltage. Firstly, AC voltage is rectified by a full-wave bridge rectifier circuit and the ripple component of the rectified current is removed by a filter capacitor. Secondly, the output voltage is regulated by a linear regulator, which is normally a single transistor.

The linear regulator compares the output voltage to an adjustable reference voltage and then adjusts the current through the transistor to keep the two voltages equal. The transistor is powered by the rectified current, and its output current is routed to the filter capacitor. Thus, the output voltage can be kept relatively stable over the input voltage range

Conclusion

SMC500PS24-C is a versatile AC-DC Converter which can be used in a variety of application fields. The two-stage circuit design makes it possible to keep the output DC voltage relatively stable over the input AC voltage range.
