Wiring method:

L is the grounding wire

N is the neutral wire

V - represents 12V negative pole

V+represents 12V positive pole

ADJ is an adjustable potentiometer that fine tunes the output DC voltage

matters needing attention:

(1) The power supply is equipped with a 110V/220V conversion switch, which is prohibited for domestic use. Otherwise, the power supply will be directly damaged and will not be replaced or repaired.

(2) Before the installation is completed and the power on trial operation is carried out, please check and calibrate the wiring on each terminal again to ensure that the input and output, AC and DC, single-phase and multi-phase, positive and negative voltage values, and current values are correct before powering on for operation.

(3) Regarding power: This power supply can be used with either 20A or 21A output, and there is no usage impact.
