Series 70: eSTS 1600 A - 4000 A

Designed to protect critical operations, and even entire buildings - the LayerZero Power Systems Series 70: eSTS is a Static Transfer Switch that maximizes power reliability. The Series 70: eSTS is designed to switch between multiple power sources very fast - less than a quarter of an electrical cycle. The eSTS features a solid-state transfer switch that automatically or manually provides static transfers between two AC sources. The eSTS is a MISO Configuration (Multiple Inputs, Single Output), and is ready to accept either 2 or 3 power sources. If the primary source goes out of specification, eSTS transfers to the secondary (backup) source.
