                  Features:
                  1. High-precision three-group four-and-a-half LED digital display: current + voltage + power, intuitive and clear.
                  2. Intelligent fan, excellent heat dissipation, effectively extending fan life and reducing noise.
                  3. USB interface, 5V/2A output.
                  4. Adopt advanced technology, effectively reduce the weight of the power supply, lengthen the handle design, and facilitate the power movement.
                  5. Regulated steady current constant current constant voltage multiple modes can be switched.
                  6. Set the coarse and fine adjustment knobs for voltage and current 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.
