Small Candeo modules
The Candeo platform uses a combination of modules or building blocks to
deliver custom configurations. The modules include:
•
Rectifier 30/48
•
Power shelves
•
System Manager SP
•
Distribution 300 panel
Rectifier 30/48
The Rectifier –48 V DC, 1500 W is a switch-mode rectifier that converts the
single-phase AC source at the input into an isolated, filtered, and regulated
DC power output (up to 30 A) used to feed the loads and to charge a positive
grounded battery. These rectifiers are of the plug-in type to facilitate their
installation, maintenance, replacement, and repair. Each rectifier is equipped
with a cooling fan that is field replaceable.
Designed to operate at a nominal input voltage of 110/120 or 208/240 V AC,
the rectifier will also operate over an input range of 75 V AC to 310 V AC (45
to 65 Hz) at reduced output power. The rectifier delivers full output power
when operating in environments ranging between –40°C (–40°F) and 55°C
(131°F).
The rectifier requires no adjustments. Under normal operation, operating
parameters of the rectifiers in a system, such as float voltage and boost
voltage, are entirely configured and controlled by the System Manager SP.
Power shelves
The Candeo SP48300 can have either one or two power shelves. The initial
power shelf provides five rectifier positions and one system manager
position, while the supplementary power shelf has six rectifier positions and
an optional AC interface box for front access applications. Each rectifier
position provides interconnection points for the AC input, the DC output, and
the control and alarm data bus (CAN protocol).
The total output capacity of the system is 300 A. The output capacity of the
initial shelf is 150 A (five rectifiers delivering 30 A each). The output
