  • The PP-2953C/U is an AC operated DC power supply that provides a regulated 22.7 to 27.7 VDC output from a 50-60Hz, 230V or 50-60Hz/400Hz, 115V input voltage source.  It has a sense circuit that switches the output to a 25.2VDC battery backup input when the AC input voltage falls below a certain value.
