Large Candeo modules
The Candeo platform uses a combination of modules or building blocks to
deliver custom configurations. The modules include:
1
Rectifier 50/48 Module
2
System Manager Module
3
Distribution 500 Module
Rectifier 50/48 Module
The shelfless Rectifier 50/48 provides up to 50 A (2 750 W) of –48 V DC
power. Designed to operate at a nominal input voltage of 208/240 V AC, the
rectifier will also operate over an input range of 80 V AC to 300 V AC (45 to
65 Hz) at reduced output power. The rectifier delivers full output power when
operating in environments ranging between 0°C (32°F) and 50°C (122°F).
Rectifier features include:
•
High power density — 4.3 W /in.
•
High efficiency (> 92%)
•
Shelfless design
•
Hot insertable
•
Tool-less rectifier installation
•
100% tool-less maintenance strategy
•
Ultra-low total harmonic distortion (THD) < 5%
•
Temperature-controlled cooling fans
•
Mean time before failure (MTBF) > 250 000
•
Zone 4 seismic
•
Compliant with global standards (FCC part 15 class B, UL 1950,
CSA 22.2#950, CE, VDE, IEC 950, and CISPR22 class B)
