Unitron's PS series frequency converter provides stable and reliable
400Hz power for testing or installing aviation equipment and
products. Whether the application requires 3.5kVA or 17.5kVA in a
shelter or close quarters laboratory, the PS series frequency
converter provides power qualified to the latest MIL-STD and RTCA
specifications while keeping the noise level low and without any
400Hz “whine.” The PS series can be mounted in any plane to a
laboratory desk or rack system.
Shelter application:
PS-94 series, PS-450/451
Single phase input
military or civilian: PS-94-444-27 series
Legacy: CR

PS-94 SERIES
Unitron’s
PS-94 Series
programmable AC power supply operates from any standard worldwide
power source, and provides 50 Hz, 60 Hz or 400 Hz output power in
various single-phase and three-phase configurations.
The unique design of the low-power bench unit allows the user
to independently select operational parameters, such as frequency
and voltage,
using a field-replaceable programming plug.
This versatility makes the unit ideal for use in research
laboratories and production line testing.
Unitron's
PS series programmable power supply is available in a standard
single unit power rating of 3.5 kVA.
When higher output power is required the units may be
paralleled to supply up to 40 kVA. |

| NOTES: |
- Programming plug (PP Series) or parallel cable
(PPC Series) required to determine output frequency and phase
configuration.
- Two paralleled units require one programming
parallel cable (PPC Series) only. Three or more paralleled units require a
programming parallel box (PB Series) in addition to one
programming parallel cable (PPC Series) for
each unit. Paralleling for grid expansion up to 17.5 kVA
only.
- Unit does not include circuit breaker.
- Requires one PC-P1 type parallel cable (PC
Series) for each
unit.
- Requires one PC-P3 type parallel cable (PC
Series) for each
unit. (Limit 3 units.)
- Portable power supply and distribution system.
- Two or more paralleled units require a
paralleling control box (PCB Series) in addition to one
paralleling box cable (PBC Series) and one interconnect power
cable (IPC Series) for each unit. Paralleling for common
output buss grid expansion (up to 17.5 kVA) or for N+1
redundancy/hot swap system configuration.
- Units meet EMI requirements per MIL-I-6181D.
- Other output frequency and voltage options
available. Contact factory.
- Includes 100 msec. ride-through option.

CR SERIES
Unitron's CR Series frequency converters provide 400 Hz 120/208
VRMS three-phase power from a 50 or 60 Hz 120/208 VRMS input source.
The units have front-panel adjustment and lock controls for voltage,
current and frequency, making it an ideal dedicated power source for
use in testing and manufacturing labs and plants. |
