The PS-94 Series is Unitron's latest generation of universal
input (30 to 800 Hz) to 50, 60 or 400 Hz output lightweight frequency
converters for airborne, shelter and laboratory
operations. This new generation of frequency converters
incorporates the latest state-of-the-art technology to meet input
power standards for low input current distortion
and a high input
power factor, while keeping the converter small in size and
lightweight. Output power ratings for the frequency
converter series are 3.5 kVA to 17.5 kVA (for higher ratings,
contact factory). Paralleling with
N+1 redundancy and
hot swap options are also available for the PS-94
Series frequency converters.
The latest development in the
PS-94 Series frequency
converters is the Programmable Power Supply. The frequency
converter is designed to operate from a wide input power
frequency (30-800 Hz), and provide 50 Hz, 60 Hz or 400 Hz output
power in various single-phase and three-phase configurations,
depending upon which programmable adapter is selected. Because
the customer is able to use the same base unit to provide any output
power frequency (50 Hz, 60 Hz or 400 Hz), the converter
can be used in a variety of applications, without having to stock or
support additional units.
As an expansion of the
PS-94 Series frequency converters,
Unitron has developed the PS-95-448-1 Medevac Portable Power System,
a self-contained, easily transportable unit to convert 400 Hz
aircraft power into a 3-station, 60 Hz power bus for medical
evacuation stations aboard military and commercial aircraft.
Each of the three stations is equipped with a NEMA 15-5R receptacle
and independent circuit breaker.
PS-94 Series offers
ride-through options up to 100ms for applications where
Mil-Std-704E power quality is needed aboard
Legacy Aircraft with an electrical
bus meeting Mil-Std-704A power quality. This attribute avoids
the necessity of upgrading legacy aircraft electrical systems when
the use of modern avionics equipment is required.
