OWER

Units typically require 20V to 56V 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 external power supply must be capable of supplying 165W, 305W or 350W for the 25W, 40W or 50W

ATOMs respectively. For CE compliant operation the external power supply must have overcurrent

protection with a current limit between 20A and 23A. The DC power cable must be capable of safely

carrying at least 10A continuous for 25W ATOMs and 20A continuous for 40W, 50W and low voltage 25W

ATOMs. Note that the power supply connection should not be made with the power live. The unit should

not be powered on until all input and output connections have been made.

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.
