                  Instructions for use:
                  Connection of the output port: The test dedicated line will be standard, red is inserted into the "+" port, and black is inserted into the "-" port.
                  Set a constant voltage: Keep the test leads open and adjust the voltage knob to get the desired voltage.
                  Set Constant Current: Place the voltage and current knobs on a small value stand, short the test leads, and adjust the current knob to get the desired current.


                  ● Full-featured output protection
                  ● Continuous output at full load
                  ● Stability, reliability and durability
                  Small size, easy to carry, save space

                  Use high quality components, power efficiency > 85%

                  ● Beautiful appearance, novel structure, overall compact and lightweight

                  The perfect combination of the side cooling holes and the rear cooling fan makes the heat dissipation better, and the power supply does not affect the service life due to excessive temperature.


                  1. Factory product testing aging: such as DC motor, DC fan, car DVD, car audio, resistors, capacitors and other products test aging.

                  2. Battery charging industry: Perfectly used in the battery charging industry, it provides constant current charging, then converts to constant voltage trickle charging, prevents overcharging, protects the battery, and effectively extends the battery life.

                  3. Inverter industry: Overcome the stuck problem of linear power relay conversion, extremely fast response speed, and meet the instantaneous changing load requirements.

                  4. LED manufacturing industry: LED testing, aging.

                  5. Everything else needs DC regulated power supply.

                  Package Included:
                  1 x DC Power Supply
                  1 x Power Cord
                  1 x Manual
