Product Introduction:
JJW3-30KVA 24vac Regulated Power Supply
24vac regulated power supply is an important power equipment, its main function is to stabilize the input AC voltage within a certain range to ensure that the subsequent electrical equipment can operate safely and stably. The following is the working principle of AC regulated power supply:
The working principle of 24vac regulated power supply is to achieve the stability of output voltage through feedback control. The control circuit will constantly monitor the output voltage, and once the output voltage deviates from the set value, the control circuit will automatically adjust the control element of the transformer to bring the output voltage back to the set range. This feedback mechanism ensures that the AC variable AC voltage stable power supply can provide a stable output voltage, which is suitable for the application of stable AC power supply;
The composition and work flow of 24vac regulated power supply:
The Ac regulated power supply usually composed of the following parts: input circuit, transformer, control circuit, output circuit, etc. The specific work flow is as follows:
1Input circuit: The input circuit of the 24vac regulated power supply is used to receive input signals from the grid or other AC power sources. Usually, it includes input filters that suppress external noise and electromagnetic interference and ensure the accuracy of the input signal;
Transformer: The input circuit inputs the AC power supply into the transformer. the transformer perform two main functions: changing voltage levels and providing electrical isolation. Relying on the voltage ratio of he transformer, then size of the input voltage can be adjusted to the required output voltage range.
Control circuit: The core part of 24vac regulated power supply is the control circuit. The control circuit usually contains a feedback loop and some control elements to monitor the output voltage and control the output of the transformer. The control circuit generates error signal by comparing the difference between the output voltage and the set reference voltage;
Transformer control: The error signal is transmitted to the control elements of the transformer (such as thyristor, thyrior, etc.), which adjust the output voltage by adjusting the conduction angle or switching phase of the winding of the transformer. By changing the relative amplitude and phase difference between the input voltage and the output voltage of the transformer, the output voltage can be adjusted and stabilized;
Output circuit: After the above steps, AC variable AC voltage regulator power supply will get a stable output AC power supply. The output can be connected to a variety of equipment or systems that require a stable power supply
