A DC regulated power supply that incorporates a transistor to increase the current output capability. To enhance system reliability, a transient voltage suppression (TVS) diode is added to the regulated output stage, providing protection for the connected instruments. This TVS diode also helps to absorb voltage spikes that may occur between the collector and emitter of the transistor, preventing potential damage. Additionally, it safeguards the transistor from excessive peak voltages that could otherwise cause failure. By integrating a TVS diode at the output of each regulated power source, the overall system becomes more robust and less susceptible to electrical transients. This design improvement significantly increases the reliability and longevity of the entire device, making it more suitable for use in sensitive or critical applications. The inclusion of such protective measures ensures stable performance under varying load conditions and improves the safety of the power supply system. ac dc adapter,dc adapter,ac adapter 12v,dc power adapter,ac dc adapter 24v FOSHAN SHUNDE KELICHENG POWER SUPPLY TECHNOLOGY CO., LTD , https://www.kelicpower.com
