Adjustable DC stabilized power supplyAdopting switch mode power supply technology without power frequency transformers, advanced switch mode power supply control technology and components, as well as careful design, the whole machine is small in size, light in weight, and high in efficiency, ensuring stable and reliable long-term full load operation.
Adjustable DC stabilized power supply is widely used in power DC screen systems, industrial control, communication, scientific research, aging testing, electroplating electrolysis, battery charging and other equipment. Adjustable DC stabilized power supply has a wide range of AC input voltage, can be used for 220Vac or 380Vac input, and can be customized for DC input. The voltage regulation value and constant current value can be continuously adjusted within the range of (0-100)% of the larger value. Adjustable DC stabilized power supply digital display meter displays voltage and current. Temperature controlled fan, automatic overheating protection; Output overvoltage, overcurrent, and short-circuit protection; Power on delay soft start to avoid output voltage overshoot during startup.
The DC power of the adjustable DC stabilized power supply is converted into high-frequency and high-voltage pulse AC power with adjustable output voltage. After rectification by a high-voltage rectifier circuit, it is filtered by a filter to achieve high-voltage DC output. Due to the high output DC voltageAdjustable DC stabilized power supplyThe output voltage is sampled through a specially designed sampling circuit, amplified by an isolation amplifier, and then sent to an A/D conversion circuit and a controllable gain amplifier. The microcontroller obtains a sampling voltage of DC high voltage through A/D and compares it with the set value; Then, after PID adjustment, the output error signal is sent to the controllable gain amplifier to regulate the error voltage; Later, the PWM controller is adjusted by the error signal to control the output duty cycle and achieve the regulation of the output DC voltage.
The adjustable DC stabilized power supply has various structures such as full bridge, half bridge, push-pull, etc. The main circuit adopts a half bridge topology structure, which has the advantages of simple structure, low pressure bearing capacity of switch tubes, strong anti imbalance ability, and difficult direct connection. At the same time, the primary of the adjustable DC stabilized power supply flows current throughout the entire cycle, and the magnetic core is fully utilized without any bias issues. The power switch tube used has low voltage resistance requirements, reducing the saturation voltage drop of the switch tube to a small level, and also has low voltage requirements for the input filtering capacitor. Therefore, half bridge topology is a commonly used structure for small and medium power supplies.
Adjustable DC stabilized power supply, as a substitute for old-fashioned power frequency DC power supply, is developing and advancing at a speed beyond people's imagination. Especially in recent years, with the product upgrades of major semiconductor component manufacturers, ourAdjustable DC stabilized power supplyGreat progress has also been made. It is worth mentioning that at the high frequency of the power supply, it is well known that the frequency of the adjustable DC stabilized power supply is an important indicator that determines the efficiency of the power supply. Only by continuously improving this indicator can the efficiency of the power supply be continuously improved.
The future of adjustable DC stabilized power supply is bound to follow the path of high frequency, only in this way can our power supply achieve high power, small size, and energy. The adjustable DC regulated power supply has always been at the forefront of the industry in terms of its high quality. Its product line uses 28cm Japanese original Baolai * intelligent temperature control fans, combined with popular dual circuit temperature control safety systems, to maintain minimal noise while dissipating heat. It has also passed strict high-temperature environment temperature tests at 60 degrees Celsius.
