The T809-10 is a switched mode power supply with universal AC input capability and
built-in active Power Factor Correction (PFC). The power supply is capable of supply-
ing 13.8V
DC
at up to 30A.
The T809-10 power supply is designed as a replacement for the T807 and T808 power
supplies, and as such, it is intended to supply T800 Series Base Stations. The T809-10
power supply is available in two configurations – the T809-10-0000 and the T809-10-
00C1 (or -00C2), as described below.
1.1.1 Description
The T809-10-0000 is a 60mm wide vertical module designed for use in a standard
483mm (19inch) T800 subrack.
The T809-10-00C1 and the T809-10-00C2 are both 2U subracks designed to fit directly
