I'm not sure of the required power spec,  but 28V may be too low.  These were meant to run off a telco power bus (nominal 48V).  
I run mine at 40V (from a Tek PS503A mounted in a TM501 mainframe,  unit connected across the + and - supply terminals,  outputs set to +/- 20V).  It won't run at 28V.

Input  voltage to the poor performing unit is about 28VDC.
