Universal Power provides Premier Static Transfer Switches (STS's)
 PDI's SBR Series Static Automatic Transfer Switch supplies your critical loads with a choice between two available sources of electrical power. The SBR continually monitors power quality and will automatically transfer to an alternate source without interruption of power to even your most sensitive critical loads. With a sense and transfer time of less than 4ms, the SBR represents the highest performance power switching solution available for the most critical applications.
25 years of experience has allowed PDI to become a preferred supplier of 4ms transfer switches to a wide range of industries. The SBR Series supplies critical loads with a choice between two available sources of electrical power. Continually monitoring power quality, the SBR automatically transfers to an alternate source without interruption of power to even your most sensitive critical loads. With a sense and transfer time of less than 4ms, the SBR represents the highest performance power switching solution available.
The SBR improves overall reliability and availability of power to your facility by:
- Providing instantaneous access to redundant sources of power
- Enabling on-line maintenance of upstream equipment
- Utilizing a solid-state transfer mechanism with no mechanical parts to maintain
- Preventing cross connection of sources during transfer and eliminating the possibility of cross current between sources
Our systems design and integration experience is packaged in every product we sell.
