J3
– DC P OWER
The unit typically requires 18V to 54V DC power. Refer to the specific configuration of the unit for the
exact voltage range. Power is supplied through a four pin type cannon connector. Two pins are used to
deliver the positive connection and two pins are used for the negative connection in order to reduce
resistance. The negative connection is internally connected to case ground. The negative power
connection may alternatively be applied directly to the outer aluminum case.

The J3 connector is a four pin cannon type cylindrical connector (AMPHENOL PT07A-12-4P). This
connector is a MIL-DTL-26482 Series 1 receptacle, Shell size 12, 4 pins. (The pins are size #16) The
connector is a “receptacle” and it has pins (as opposed to sockets), and requires the mating connector to
be a “plug” with four sockets. An example mating connector would be Amphenol # PT06E-12-4S-SR. A
range of other plug-compatible Amphenol part numbers for the mating connector may be used to add
options to the plug such as right-angle, stress relief clamp, metal color/finish, etc. Please contact the
connector manufacturer for more information and/or see Amphenol catalog 12-070.
