Description

Twins PRO series, a redundant power supply, is designed for standard ATX or PS2 chassis, no front end braket needed, ideal for mail, web or home server. Hot swappable modules design provides stable power supply; when one fails, the other can take over the load immediately. Thus users do not need to worry about any server/PC power off situation.Redundant system design and built-in hot swappable modulesWith redundancy in mind, the Twin Pro modular system design is more efficient and operates more quietly by distributing the power load between two hot swappable PSU modules. If one unit fails, the second unit takes control of the power load until a replacement is swapped in. Each unit can be hot swapped and replaced without any system down-time offering a seamless and uninterrupted operation.Black ribbon cable designThe round black ribbon cable design helps with heat emission effect and extends the life span of the components. The ribbon cable design also offers a cleaner aesthetic and allows for better cable management in custom build systems.Power cord locking deviceThe Twins Pro series features a power cord locking device that secures the power cord from acciedntal disconnect helping to ensure stable operation without any system interruptions.Twins_Pro Power Cord Locking DeviceGuardian logoFSP GuardianPropreitary user interface software that monitors status in real-timeGuardian displayThe Twins PRO series can be connected to a USB header and synced with the FSP Guardian software to monitor power input, power output, efficiency, and other internal records in real-time.
