Redundant system design and built-in hot swappable modules
With 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.

Ideal for home, mail or web server systems
The Twins series is an ATX PS2 size redundant power supply. The Twins Pro does not have front-end brackets, which makes it an deal power solution for a home cloud server, mail server, or a small to medium-sized enterprise (SME) web server.
