12 Introduction
UM5C06D ( 169-2071-504 ) P0831010 Standard 7.00 May 2001
Applications
The rectifier is designed to function as the prime source of power for
equipment requiring -48 V DC. It will also operate as a battery charger or as
a battery replacement (batteryless operation). Its low output noise and good
voltage regulation, combined with a 0.01% V coefficient for each degree C of
temperature, provides an excellent charging facility to maintain a battery fully
charged.
The NT5C06D rectifier is designed to operate continuously in a small or
large power system. The NT5C06D is compatible with all other Astec
rectifiers, and can be interfaced with other commercially available standard
(compatible) rectifiers and power plants. The NT5C06DA/DB is designed to
operate in temperatures ranging from 0°C to 65°C.
Equipment Identification
This section contains a description of the major components and available
options for the NT5C06D Rectifier, and the MPS75 power shelves.
NT5C06DA -48 V / 25 A Switch Mode Rectifier, brown
NT5C06DB -48 V / 25 A Switch Mode Rectifier, dolphin grey
NT5C10C(X) Rack mount power shelf family, 23” mounting
Note: Many shelf models, with different colors and features, are
available.
MPS75 NT5C10C(X)
power shelf (23-inch)
The MPS75 is a power shelf that can support up to three NT5C06 rectifiers.
The rectifiers plug into the shelf, which provides interconnection points for
AC input, DC output, and alarm and control signals. Each power shelf
requires either three AC feeds (one for each rectifier) for the individual AC
models, or a single AC feed for the three shelf rectifiers for the common AC
models. Its output connects to the charge busbar or to the load distribution
panel through two cablesbattery and battery return. Each rectifier position
has its own connector-terminated alarm and control cable going to the power
plant control and monitor unit.
