by Rebecca Walker — August 9, 2010—WTI has just released a fail-safe power transfer switch for single power supply devices needing automatic switching between primary and secondary power sources.
The PTS Automatic Power Transfer Switch allows for two inputs from a primary and secondary power source to deliver redundant power to single power supply devices. When power is lost on the primary input, the PTS immediately begins drawing power from the secondary input in less than one cycle or 8 milliseconds on average, according to the company. Continuous source monitoring ensures that no matter what time of day or night a failure occurs, the single power supply equipment is still receiving power.
The new automatic power transfer switches were designed to give existing power strips and smart PDUs the ability to switch between A and B power sources. There is no need to remove existing smart or switched PDUs from racks or cabinets when installing a PTS. Just plug the input from the strip or PDU into the PTS and you have just created a dual fail-safe redundant power source without rewiring your equipment.
Automatic fallback switching of the PTS also allows for hands-free power fallback between primary and secondary sources. Unlike other solutions, the PTS can detect when power is restored to the primary input and automatically fallback to the primary power source.
