We are now on Chinese New Year Holiday. You can keep placing orders. But we will resume processing them after February 9th.
DC Power Supply LW PS-303DM 0-30V 0-3A


A good 30V/3A power supply. With 0-30V you have the right voltage for most low voltage applications, MCUs and motors while 0-3A provides enough current for the most low power applications.
The big red display shows you precisely what voltage and current you have set, while the fast reacting current limitation protects your precious circuit against being destroyed.


  • 0-15V / 0-3A output
  • good price
  • bright display
  • precise voltage and current setting
  • precise current measurement
