Introducing Nova's Rugged 400-1200 VDC Input Galaxy-Series DC-AC Inverters

600-750 VDC Nominal Input / Pure Sine-Wave Output

For Work Trains, Trolleys, and Mass Transit Stationary Applications

Partial Standard Model Selection - Please consult factory for custom applications

*Three-Phase Inverters: Nova Galaxy Series inverters can be arranged for three-phase operation by the customer upon request. We accomplish this by packaging three separate single-phase inverters as one three-phase unit or as a series of modules. All popular nominal DC input voltages and AC output voltages are available upon request, in sizes from 1.5-60+ KVA. Please (C/F) consult the factory for details.

EXPERIENCE COUNTS! Our experience in this field is the most valuable resource we offer to our customers. Nova's 600 VDC and 750 VDC inverters are currently being used throughout the world in the most demanding Mass Transit applications. Some of the projects we've worked on include:

Work Train Applications: Inverters in various sizes, from 5-20 kVA, are currently utilized by such customers as Amtrack and the MBTA for powering equipment on third rail 450-750 VDC Work Train Applications. Everything from hand tools to lighting run on Nova inverters. Even on-board electric toilets are powered by our inverters!

Trolley Applications: Nova has supplied specialized inverters for many custom Trolley Applications.  In addition to our other custom designs, we have designed and built special inverters modified to accept 900 VDC continuous input at the customer's request. Nova inverters are also used to power lighting on Historic Trolley Systems across the country. The next time you see a restored trolley, remember that the lights are probably powered by Nova!

Subway Applications: Our durable 600 VDC inverters are currently being used by such customers as Chicago Transit Authority and Long Island Railroad for such various applications as providing emergency power from the third rail. Quite often, it is cheaper and more pragmatic to install an inverter in a hut (shed) on a siding than to run AC power from a distant location. 

Custom Applications: Nova offers an almost infinite combination of custom cabinets and configurations to satisfy almost any application! Mobile applications, as well as outdoor applications subject to rain, snow, ice, wind, etc. are one of our specialties! Our inverters are extremely rugged by design, and feature an advanced Internal Suppression Filter Network to suppress the significant transients usually associated with these applications. Please don't hesitate to contact the factory for additional information.
