Redefining Static Transfer Switch Technology

MGE has redefined the Static Transfer Switch with the advent of the Epsilon class STS using a host of next generation features that provide unparalleled reliability. At the heart of the STS is a failsafe logic system featuring the latest generation FPGA (Field Programmable Gate Array) circuitry to assure reliable source transfers under all conditions. The logic is fortified by isolated triple redundant power supplies and an inherently safe operating architecture. Leaving nothing to chance, redundancy is found on all critical assemblies on the Epsilon STS. Designed to be truly fault tolerant, the Epsilon STS has the ability to safely clear short circuit faults due to a robust 300% up to 400 A overrated disc type SCR power assembly, solid copper bussing and fuseless current path. All internal assemblies are placed in draw out or hinged panels to facilitate rapid, front only access for inspection and eliminate wasted access space requirements. The latest product from MGE, the Epsilon STS is one more reason that over 95% of the Fortune 100 trust MGE for their critical power protection.

Rapid, Seamless Transfer

Fast, seamless transfers: The Epsilon STS uses an FPGA hardware based instruction set that allows it to compute transfer algorithms faster than software based systems. The result is faster, seamless transfers under all conditions.

Triple Redundant Isolated Bus Power Supplies

True Triple Redundant Power Supplies: The reliability of a Static Transfer Switch hinges on the integrity of it's logic power supplies. The Epsilon STS uses three redundant power supplies each with an isolated bus. While other STSs may have redundant power supplies a short on the DC bus can fail all the supplies. The Epsilon has three separate and isolated connections with each supply going to a dedicated connection on the various PCBs.

Intelligent Fault Isolation

Preventative Fault Propagation: When a fault occurs on a load, it can sag the voltage on the whole critical bus. Under fault conditions it is not a wise idea to transfer to the alternate source without the fault clearing first as this will simply sag the voltage on the alternate bus, corrupting all the loads fed by that bus. The Epsilon STS has the intelligence to recognize downstream faults and lock onto the source in the event of a fault condition. The result is that it will not propagate the fault onto the alternate bus

Fuseless Current Path

The Epsilon STS uses 200% to 600% overrated disc SCRs allowing to sustain even dead shorts from 65 to 100 KAIC with no damage to the device. This robust current path ensures that you stay on-line even in the most adverse conditions.
