Din-Rail Power Supply is a power supply device used in the field of industrial automation. It is usually able to convert input power into the required DC or AC power and provide it to the equipment or system. Its working principle mainly includes the following steps:
Rectification: Din-Rail Power Supply first receives input power from an AC power source (such as mains). If DC power is required to be output, there is usually a rectifier at the input of the power supply. The function of the rectifier is to convert the alternating current signal into a direct current signal. This is usually done with a diode bridge rectifier circuit, which converts the negative and positive half-cycles of the AC signal into a DC signal in the same direction.
Filtering: Since the rectified output may still have a certain degree of fluctuation or ripple, filtering needs to be performed to reduce the ripple. A filter capacitor is usually connected after rectification, which can level the fluctuating DC level and make the output more stable.
Voltage stabilization: In some cases, the output voltage needs to remain stable and not affected by input voltage changes or load changes. Therefore, Din-Rail Power Supply may be connected to a voltage stabilizing circuit after filtering. The voltage stabilizing circuit can adjust the output voltage as needed to ensure that the output voltage is stable within the set range.
Inverter (optional): If AC power output is required, inverter operation is usually required after rectification. The inverter converts the DC signal into an AC signal. Inverters usually use PWM (Pulse Width Modulation) technology or other forms of electronic switching technology to control the shape and amplitude of the output AC voltage.
Output: Finally, the electrical energy after rectification, filtering, voltage stabilization (optional), inverter (optional), etc. will be provided as output to the connected device or system.
In general, Din-Rail Power Supply converts the input power into the required DC or AC power through rectification, filtering, voltage stabilization (optional), inverter (optional) and other steps, and provides it to industrial automation System or device usage.
