PORTABLE AC POWER WHEREVER AND
WHENEVER YOU NEED IT!
Rugged, Lightweight Design for
Harsh Environments
22-32 VDC Operating Input / 1 kVA
- 3 kVA
Product Description:
This specialized series of inverters was developed specifically for mobile
military applications, and is currently in use by NATO forces internationally. The rugged,
lightweight design and portable enclosure, coupled with Nova's proven reliability, make
this series ideal for any Harsh Environment application! These units are especially
designed for use in ground vehicles, to convert 28 VDC vehicle battery power into AC
to power test equipment or various instrumentation. The inverters can be either
mounted within vehicles or easily hand-carried by one person. In addition to the standard
equipment found on our standard Galaxy-Series inverters, the MILITARIZED
PORTABLE models also
contain other key features, including:
- Wide Temperature Operation - Can
withstand operating temps between -40 to +60 degrees Celsius
- Extensive EMI Filtering - The
inverters feature an Input EMI Filter for attenuating input noise and common mode noise to
comply with portions of MIL-STD-461. An Output EMI Filter is also included to filter the
output leads and deliver clean power to the load.
- Heavy-Duty Input Circuit Breakers -
Act as ON / OFF switch and as additional protection. (rating varies by model)
- Additional Ruggedization - The
inverters are ruggedized against shock, vibration, and humidity to meet MIL-STD-810. In
addition, all boards are conformal coated for extra protection against high-humidity and
potential fungus growth.

*Three-Phase Inverters:
Nova IGL-Series and GL-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 consult the factory for details.
