Section 1. DCPS-SHELF-9KW Overview
Operating Deratings:
The DCPS-SHELF-9KW Rectifier Shelf is designed to operate with the AC
input voltage between 85V to 285V and in conditions with an ambient temperature of -40
°
C to
+75
°
C (maximum). However, the output power is derated when the AC input < 176V (see Figure
2) and when the operating ambient temperature > +45
°
C (See Figure 3).
AC Input Voltage Derating:
The DCPS-SHELF-9KW Rectifier Shelf is designed to operate in
conditions with the applied AC input voltage between 85Vac to 285Vac. Each Rectifier Module is
capable of providing full DC Output power when the AC input voltage is 176V or higher. Each
Rectifier Module’s DC output power derates when the AC input voltage is below 176V, as shown
below.

Temperature Derating:
The DCPS-SHELF-9KW Rectifier Shelf is designed to operate at full power
with no temperature derating up to +45
°
C. In a > +45
°
C to +75
°
C (max) ambient temperature
environment, the Rectifier Modules power derate as shown below.
