                  1. High-precision LED digital display, intuitive and clear.
                  2. 8 cm intelligent fan, excellent heat dissipation, effectively extend the life of the fan and reduce noise.
                  3. Using advanced technology, it effectively reduces the weight of the power supply and facilitates power supply movement.
                  4. Multiple protection functions, current limit protection (OCP), over temperature protection (OTP), over power protection (OPP).
                  5. Plastic panel, more beautiful, voltage and current set coarse adjustment and fine adjustment knob to make the setting more precise.
                  Application areas:
                  1. Charge the battery.
                  2. Car DVD, car audio.
                  3. Product aging, such as resistors, capacitors, relays, DC motors, LEDs, etc.
                  4. Laboratory, factory, maintenance power supply.
                  5. Everything else needs a DC regulated power supply.
