4.6.2 Power Supply
There are three ways to supply power to the CPU board and inverter board, and the power supply for the
communication board is independent of the CPU board and inverter board and is supplied at 5V from the
USB connector.
(1) From DC jack
Use an AC adapter or something similar to supply power from the DC jack (J1) on the inverter board. The
compatible plug has an outer diameter of 5.5 mm, an inner diameter of 2.1 mm, and a polarity of center
positive. The input voltage range is 12 to 48V.

(2) From terminal block
Supply power from the terminal block (CN1) of the inverter board using a DC stabilized power supply or the
like. The polarity should follow the silk indication (“+”, “-“) on the board. The input voltage range is 12 to 48V.
