Switching power supply meets voltage trimming requirements

Switching power supply meets voltage trimming requirements
An AC/DC switching power supply, which has an output power of up to 10KW, has been introduced by MEAN WELL. The RST-10000, which adopts 3-phase AC input, is available with three nominal outputs: 24, 36 or 48VDC. To meet the voltage trimming requirements, users can apply external DC voltage control to adjust the output voltage and current.
