Static transfer switch PDI

The PDI Static Transfer Switch supplies critical loads with a choice between two available sources of electrical power. By continually monitoring power quality, the PDI Static Transfer Switch automatically transfers to an alternate source within a quarter cycle and without interruption of power to even your most sensitive critical loads. Triple redundancy The true system redundancy provides the ultimate in power system reliability. Compact enclosure, modular design Modular interior design results in higher quality throughout the product line and the new 2000Amp has the smallest footprint in the industry. Rigorous five-step quality process (1) vendor quality partnership using PDI designed test equipment and procedures, (2) functional component testing, (3) component level tests in simulated STS environment, (4) module level test, and (5) verification of final product system performance. Volt second synchronization The PDI Static Transfer Switch transfer algorithm is optimized to switch power sources quickly all while minimizing voltage disruptions and preserve transformer flux balance. This is achieved by rapidly firing the SCRs to establish a balance point as quickly as possible by analyzing the voltage disruption and volt-second balance. The result is a faster and cleaner transfer of power with typically 1X unit rating or less in rush current regardless of the load make up and size. Dual redundant display In the event of a touchscreen display failure the PDI Static Transfer Switch can be operated via the redundant operator interface.
