50V 30A High Power Digital Benchtop Switching DC Power Supply

  • High-precision LED digital display, intuitive and straightforward.
  • 6 cm intelligent dual temperature control fan, excellent heat dissipation, effectively extends the fan’s life and reduces noise.
  • Using advanced technology effectively reduces the weight of the power supply and facilitates power supply movement.
  • Multiple protection functions, fixed overvoltage protection (OVP), current limit protection (OCP), over temperature protection (OTP), and over power protection (OPP).
  • The current and voltage are adjusted by coarse adjustment and fine adjustment potentiometer, which makes the adjustment and output more precise and convenient.
