AC/DC power supply

PWMthree-phasedigital

This power supply has the following characteristics: (1) High efficiency and energy saving: through the adoption of full range soft switch technology, digital control technology and optimized design of each link, the overall efficiency is over 92%, the power factor is over 0.95; it is more than 3% energy saving than ordinary hard switch high-frequency power supply, and more than 7-10% energy saving than traditional SCR power supply; (2) Promote production capacity: due to the high accuracy of power control, small ripple, the output can accurately meet the process demand, which is 2-15% higher than the production efficiency of ordinary high-frequency power supply; (3) Small size and light weight: the volume and weight of the series products are only 2 / 3 of the common high-frequency power supply device with the same capacity and 1 / 4 of the silicon controlled power supply with the same capacity; it can save a lot of copper and iron materials, facilitate the handling and installation, and occupy small space. (4) Green and reliable: the electromagnetic compatibility and overall heat dissipation of the device are optimized in the front. Through soft switch, power factor correction, fault diagnosis, multiple protection and comprehensive reliability design and other measures, the power supply device has good reliability and less electromagnetic pollution; (5) Digital intelligence: power management, control mode and PWM output realize all-round digitalization, power output is flexible, interface is convenient, and has the functions of state monitoring, multi machine collaborative control, etc;
