2.8 Power Supply

The NET232 can use any DC power source from 9VDC to 24VDC. A typical power cube sent with the unit
can supply 9VDC at 500 mA. However, there are other units that can be used as long as they are in the
range of 9-24VDC and supply the proper wattage. At 9VDC, the NET232 will draw approximately 110mA
(.99W) so a 2 Watt power source ( 9V at 200mA) should be adequate.
Note: Grid Connect can supply a special cable adapter to connect the NET232 to a USB jack for +5VDC power.
The NET232 power adapter is a 2.1mm, positive center power jack. The jack is equivalent to a CUI Inc. PJ-
002A power jack.
You can also order the NET232 with a Phoenix right angle power connector. The unit is supplied with a
mating Phoenix terminal block plug.
