either 1,2,3, or 4 Rectifier Modules in the Main Shelf
Section 1. DCPS-FRS-2421K Overview
Operating Ambient Temperature Derating:
The DCPS-FRS-2421K Rectifier Shelf is designed to
operate
in ambient conditions with a temperature of -10
°
C to +55
°
C but power is derated above
50
°
C.
AC Input Voltage Derating:
The DCPS-FRS-2421K Rectifier (Main) Shelf is designed to operate
inconditionswith the applied AC input voltage between 93Vac to 275Vac. Each DCPS-NDRM-2100F
Rectifier Module iscapable ofproviding full DC Output power when the AC input voltage is 176V or
higher. However, eachrectifier module’s DC output power derates when the AC input voltage is
below 176V, as shownbelow.

Rectifier
Shelf depending
on
the AC input voltage and the number of Rectifier Modules in the Shelf.
