ABB CP-E 24/1.25 Power supply

Attention! High voltage! Danger to life!

Working principle

The operation of ABB CP-E 24/1.25 Power supply is based on the principle of switch mode power supply. Firstly, the input AC voltage is converted into a DC voltage through a rectifier circuit, which is filtered to remove impurities and obtain a smoother DC signal.

Then, the DC voltage is chopped into a high-frequency pulse signal through a high-frequency switch circuit, and the duty cycle of the high-frequency pulse signal can be adjusted based on the feedback signal of the output voltage. By using a high-frequency transformer for voltage conversion, the voltage is adjusted to the required 24V DC voltage level.

Next, the high-frequency pulse signal is converted into a stable DC 24V output through rectification and filtering circuits. Throughout the process, the output voltage is monitored in real-time through a feedback circuit. When a change in the output voltage is detected, the feedback signal is transmitted to the control circuit, which adjusts the working state of the high-frequency switch circuit based on the feedback signal, thereby achieving precise adjustment and stable control of the output voltage.

At the same time, the built-in protection circuit of the power supply will monitor input and output current, voltage, internal temperature and other parameters in real time. Once an abnormal situation is detected, the corresponding protection mechanism will be triggered immediately to ensure the safety of the power supply and connected devices.
