The DC regulated power supply is a high-precision DC linear power supply with continuously adjustable voltage and current, and automatic conversion between voltage and current stabilization. The DC output voltage can be continuously adjusted from volts to volts, which is stable and reliable. The output current can be selected arbitrarily, and has current limiting protection and long-term short circuit protection. When the power supply is working in a stable voltage state, the current stabilizing part is the protection circuit. When the power supply is working in a stable current state, the voltage stabilizing part also plays the role of voltage limiting. The two protect each other to ensure the safety and reliability of electricity. The adjustable DC stabilized voltage and current power supply is composed of a transformer step-down, rectification and filtering, a reference power circuit, a reference voltage circuit, a voltage stabilization and current stabilization comparison amplifier circuit, an adjustment circuit and a flow stabilization sampling circuit. When the output voltage changes due to changes in power supply voltage or load current, the changed signal is compared with the reference voltage through the voltage stabilizing sampling circuit. After the error signal is amplified by the comparison amplifier, the amplifier circuit controls the adjustment tube to adjust the output voltage to Desired point.
The power supply also has small size, good performance and beautiful appearance. It can be widely used in industrial production, university laboratories, research institutes, postal and telecommunications and automation equipment.
Various non-standard linear DC power supplies can be customized, as well as high-voltage and high-current DC adjustable power supplies can be customized
