30V 40A 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.
