Infnity Rectifers
• Compact - 1RU form factor providing high power density (24 W/in3)
• Plug and Play – installation of the rectifer in a shelf connected to a compatible system
controller initializes all set up parameters automatically. No adjustments are needed.
• Extended service life – parallel operation with automatic load sharing ensures that
parallel units are not unduly stressed even when a unit fails or is removed.
• Monitoring / control – the built in microprocessor controls and monitors all critical
rectifer functions and communicates with the system controller using the built in
Galaxy Protocol serial interface.
• Fail safe performance – hot insertion capabilities allow for rectifer replacement without
system shutdown; soft start and inrush current protection prevent nuisance tripping of
upstream breakers.
