electronics board in the case. Connect power to the 3-pin screw terminal inside the
connection case.
The power supply is nominally rated for 24VDC but can accept a voltage in the range of
10 to 30VDC. The inputs are reverse polarity, surge, over-voltage, and over-current
protected. The power supply is not isolated.
