Espey Manufacturing & Engineering Corp.
Industrial
Espey is a leading edge supplier for the Industrial Power Supply technology. Espey designs and manufactures Industrial AC to DC and DC to DC Ruggedized Power Supplies. Each industrial application has its own set of challenges with demanding environments. Industrial Ruggedized Power Supply, Industrial Power Supply Manufacturer, Industrial AC DC Power Supply and Industrial DC DC Power Supply.
Espey has taken on many challenges from dusty and dirty locations to the extent of submersible power applications. Although the mainstay of power applications that we design are customer specification driven, the development of our configurable chassis power supplies in the section will allow for quick turn quote response and short lead times.
Our designs are geared for Transportation, Power Generation, Alternative Energy, Mining, Construction and Industrial Equipment, Metro, Bus, Aircraft, Smart Grids, Our Industrial Product Line is fully configurable with some Special Features to meet the Industrial market requirements such as short lead time, universal AC input, power factor correction, over temperature protection, no minimum load, over voltage protection and front to back airflow.

Rail Power Systems
For over 20 years, the world’s largest locomotive and rail car manufacturers have relied on Espey to deliver rugged, reliable power management and conditioning components required for the harsh environment and long MTBF’s common in the freight and light rail markets.
In an industry that is becoming increasingly global and competitive, locomotive “up-time” has become a critical determinant in the selection of locomotive and car suppliers. Operators expect high MTBF’s, long life and maintenance-free operation in the difficult vibration and temperature environments common to rail. Espey delivers that capability.
Whether in power management and switching operations of diesel –electric locomotives, or the critical electro-hydraulic braking systems electronics modules, Espey’s products have logged tens of millions of miles of maintenance-free operation.
Espey also maintains a robust logistics and repair capability to service long-lived components; when those Espey components have exceeded their designed life, they can be returned for refurbishment and re-issue for many more years of service life, further stretching operational value.

Vehicle Power
Long before hybrid electric cars appeared on U.S. highways, massive hybrid-electric mining trucks –some as tall as three stories—were hard at work extracting coal and surface minerals at mines around the world. At the heart of those massive machines were rugged and reliable power supplies from Espey Manufacturing & Electronics, converting unregulated DC battery power to regulated DC power for controls and emissions systems of the vehicle.
Off-road industrial vehicle manufacturers worldwide rely on Espey for innovative design and demonstrated endurance in harsh environments.
