SR05S12

SR05S12 application field and working principle

The SR05S12 is a kind of DC-DC converter developed by Shenzhen Sunrich Automation Technology Co., Ltd and it is widely used in multiple application fields such as industrial automation, communications, transportation, energy and fast charging, etc. It is characterized by its high efficiency, low temperature rise and high reliability. Therefore, it has won the favor of many customers.

The SR05S12 has a wide input voltage range of 18-75VDC and can provide a variety of output voltages such as 3.3V/5V/12V/24V, etc. The maximum output power reaches 150W and has a typical efficiency of 95%. The output voltage accuracy is 1~3% of the rated output voltage and the load regulation is 0.5%.

The SR05S12 DC-DC converter adopts step-down constant current switching technology to increase the efficiency and reduce the power loss. It features synchronous rectification and a patented constant-current multiple synchronous rectification technology. It uses a higher forward voltage synchronous rectification diode than traditional synchronous rectification, which is the key to the class V efficiency and low temperature operation.

The working principle of SR05S12 DC-DC converter is based on a switching regulator. It is made up of an input power source, an inductor (L), a switching transistors (ST), a rectifier (D2) and a filter capacitor (Cout). When the transistor is in a conduction state, current flows from the input source to the inductor (L) and the stored energy in the inductor increases. When the transistor turns off, the stored energy in the inductor (L) will flow from the rectifier (D2) to the output capacitor (Cout) to keep the voltage of the capacitor stable.

In summary, the SR05S12 is a high-efficiency DC-DC converter with a wide range of input voltages. It adopts constant-current multiple synchronous rectification technology to achieve high efficiency, low temperature rise and high reliability. It is widely used in multiple application fields such as industrial automation, communications, transportation, energy and fast charging. It is definitely your best choice for your power supply needs.
