Nipron's Unique Primary Redundant Power Supply
pNSP2U-550P-AAS • Much higher efficiency, reliability and less temp.rise than existing redundant power supply with our unique patented technology
• 550W large-capacity power supply to meet SSI-ERP2U specifications (including the operatioin with single unit)
• Output connector method responding to a variety of connector types
• Power delivery ratio between two input units controlled by external signal
• With a primary unit combined, higher safety or economic efficiency is selectable.
