Since 1966, Nova Electric has been a valued supplier of American-made ruggedized AC Power Sources for harsh environment and military applications. The product line consists of Pure Sine Wave DC-AC Inverters, True On-Line UPS Systems, and Solid-State Frequency Converters in the 120 VA to 500+ KVA single and three phase power range. Custom EMI Filters, Portable Rugged Transformers, Power Distribution Units (PDUs,) and Maintenance Bypass Switches (MBSs) are also offered. Nova power sources are offered in a wide variety of standard COTS configurations, which can also be quickly customized per each customer’s unique application.
Most of Nova Electric’s research and development efforts are spent on furthering our flexible architecture designs, which are suitable for the most demanding, harsh environment applications in their standard configuration. For special applications, this flexible architecture allows for quick adaptation and customization, based on the specific requirements. This website presents mainly standard COTS DC-AC inverters, UPS systems and Frequency Converters. For a majority of applications including military, the COTS products shown do not require any modification or customization. However, the company has a vast catalog of custom designs which are not shown due to the sensitive nature of the programs we support.
Nova Electric has built a formidable reputation as a reliable supplier to the military, industrial, and commercial marketplaces, by focusing its efforts on constructing reliable products, at a reasonable cost, and delivering on time. Nova Electric participates in high profile defense programs worldwide, for land, sea, and air applications. Our products are specified by all branches of the United States Armed Forces, the Israeli Navy and Air Force, the Canadian DND, the British Navy, the Australian Department of Defence, the Spanish Navy, the Italian Navy, and NATO Forces, to name a few. Nova power also boasts a loyal following among the major defense contractors such as General Dynamics, Raytheon, Lockheed Martin, DRS, Northrop Grumman, Dynetics, and Boeing. Nova’s COTS products, which are offered to industrial and commercial customers, benefit from the same quality and robust construction as the military designs. Industrial and commercial customers span a diverse array of fields, including electric utility companies, mines, steel mills, airports, telecommunication companies, and railroads.
Product Overview
Nova Electric’s product mix consists primarily of Pure Sine Wave DC-AC Inverters, True On-Line UPS Systems, and Solid-State Frequency Converters. Nova power supplies are used frequently in railway applications featuring rail inverters, rugged subway DC AC inverters, third rail inverters and PTC power supplies. These AC Sources are normally sold off the shelf or ruggedized against shock, vibration, and humidity to satisfy most military applications. In addition, most of Nova’s standard products can be modified or customized to meet specific requirements.
The Pure Sine Wave DC-AC Inverters span the 120VA to 320+ KVA power levels, in most standard nominal DC inputs including 12, 24, 36, 48, 72, 120, 155, 240, 600, and 750 VDC. AC Outputs offered include any standard single phase voltage (120 or 220 VAC) or three-phase voltage (120/208, 220/380, or 277/480 VAC), in 50 Hz, 60 Hz, or 400 Hz versions. Special frequencies (such as 100 Hz) for rail applications are available upon request. Our inverters are offered in freestanding, rack-mount, and NEMA cabinet configurations as required, though the standard enclosures are as shown.
The True On-Line UPS Systems are offered in 500W to 500+ KVA power levels, in any standard single phase voltage (120 or 220 VAC) or three-phase voltage (120/208, 220/380, or 277/480 VAC), in 50 Hz, 60 Hz, or 400 Hz versions. Most of our UPS Systems can also function as voltage / frequency converters, with the ability to convert a given single or three phase AC input to another single or three phase AC output, in conjunction with the usual battery back-up capabilities. Many models also offer a wide-range input function, which allows the UPS to operate automatically on either a 120 or 220 VAC, 50 or 60 Hz input voltage. Our UPS Systems are offered in freestanding, rack-mount, and NEMA cabinet configurations as required, with the standard enclosures are as shown.
The Solid-State Frequency Converters are available in 120 VA to 500+ KVA power levels, and can convert any standard single phase voltage (120 or 220 VAC) or three-phase voltage (120/208, 220/380, or 277/480 VAC) to another. Every model is available in 50 Hz, 60 Hz, or 400 Hz input or output. Alternative frequencies (such as 100 Hz for special railroad applications) are available upon request. All of these converters boast the superior reliability, reduced maintenance costs and noise levels, and more compact, lightweight dimensions that can only be achieved utilizing a modern solid-state design. These converters are offered in freestanding, rack-mount, and NEMA cabinet configurations as required, though the standard enclosures are as shown.
Related products such as Custom EMI Filters, Portable Rugged Transformers, Power Distribution Units (PDUs,) and Maintenance Bypass Switches (MBSs) are built to order, either based on existing standardized designs shown herein or as pure custom clean sheet designs.
Many of Nova Electric’s models feature sophisticated PWM technology, microprocessor control, comprehensive display panels, and advanced communications capabilities. All can be ruggedized against shock, vibration, and humidity to meet MIL-STD-810. These power sources are offered in a wide variety of standard COTS configurations, which can also be quickly customized per each customer’s unique application. However, for a majority of applications, the COTS products shown do not require any modification or customization.
Company Structure
Nova Electric is an autonomous division of Technology Dynamics, Inc. (TDI), a privately owned power supply company specializing in the design and manufacture of switch-mode power supplies, switching power supplies, high voltage power supplies and DC-DC converters. TDI acquired Nova Electric in 1990 from the Hobart Brothers conglomerate, to add its AC products to TDI’s existing line of DC power supplies. Nova Electric is a sister division to Mid-Eastern Industries, a company specializing in the design and manufacture of high-precision linear power supplies. As a whole, the company currently employs 150 professionals, of whom over 30% are engineering staff. The President of the company is a regular contributor to prominent technical conferences and journals.
TDI and Nova Electric often collaborate technologically to offer extremely advanced COTS and customized supplies which have both AC and DC capability – these supplies are usually designed for specific military applications (such as powering weapons systems in “Fast Attack” submarines) and are built to order. Some examples can be found on our Custom Designs Page.
