Strata Power Cables
TXU and TCU
These units use a KPT06F12-8S 8-pin female cable-mount power connector (
MRC P/N = 52155-37). Pins
A, B and C are the Positive (+) voltage input connection. Pins D, E and F are the Negative (–) voltage
connection. The current drain for these units at 28 volts DC is approximately 1 ampere each. Please see
the power cable-connector pin-out sketch below for connection details.

HPU
The HPU device is powered via the center conductor of the coaxial cable connection to the companion
TXU (early version). The current drain for this unit at 28 volts DC is approximately 3 amperes when the
transmitter is activated.
