1. Product Introduction The series of switching DC regulated power supplies produced by Jinan Nenghua are reliable and high-performance DC power supplies in application fields such as product research and development, product integration, product certification, production testing and aging, automated manufacturing testing and process control. . The product adopts high-frequency hardware adjustment soft switching control technology and has AC and DC compatible input and various protection functions. Using imported module power devices and full-bridge conversion technology, the high-efficiency products are optimized for linear power supplies and silicon rectified power supplies with specific characteristics such as high efficiency, high precision, high stability, and small size. They can operate reliably for a long time and have strong overload capabilities. Alias: adjustable switching power supply, adjustable DC regulated power supply, high-power DC regulated power supply, DC adjustable regulated power supply, DC power supply, high-power DC power supply.
The voltage and current value of the series switching DC stabilized voltage and current power supply can be continuously adjusted from zero to the rated value, and the constant voltage and constant current can be automatically converted within the rated range and the protection points can be selected arbitrarily. Voltage and current are displayed digitally at the same time. The built-in temperature-controlled cooling fan can effectively dissipate heat and extend the life of the fan. The product has protection functions such as overvoltage, overcurrent, input phase loss, input undervoltage, input overvoltage, short circuit, and overload. Start-up delay soft start avoids overshoot of the startup output voltage. The product can be used with multiple parallel-serial machines to achieve power expansion. Product control can be optional with manual knobs, buttons, computers, etc.
The current series of switching-type DC stabilized voltage and current power supplies are widely used in electric power, industrial control, communications, scientific research, railways, automobiles, ships, battery charging, aerospace, surface treatment, electrochemistry, new energy, capacitors, motors, Sewage treatment, electronic product production and testing, lighting, heating, geological exploration, medical equipment (R), semiconductor equipment (), vacuum coating equipment and other industries. Many domestic enterprises and units have used a series of DC stabilized voltage and current power supplies for product testing and aging. In addition, many scientific research units, military electronics research institutes, aviation electrical appliances, non-ferrous metals and other units use this power supply to conduct scientific research under high-precision and high-intensity power supply. The work was well received.
