PTION
The DC unit typically requires 18V to 54V DC power. Refer to specific configuration of the unit for the
exact voltage range. Power is supplied through a four pin type cylindrical 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.
Connector Type
The J3 connector for the DC unit is a four pin cylindrical connector (AMPHENOL MS3102E22-22P). The
connector is a “receptacle” and it has pins (as opposed to sockets), and requires the mating connector to
be a “plug” with 4 sockets. A range of 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. An
example mating connector is MS-3106E22-22S. Please contact the connector manufacturer for more
information and/or see Amphenol catalog.
