GROUND - MILITARY POWER UNITS
(500VA-300kVA)
400Hz Frequency Converters &
28VDC Power Supplies
28VDCPowerSupply
FEATURES:
• Used as a DC power supply unit or voltage simulating test for
GPU / Military Unit
• 28VDC ±10% Standard Output Voltage; 100Amp to 2,000Amp
Output Current
• Automatic Input Line Monitoring
• Output Voltage and Output Current Monitoring
• Current Limit Adjustable
• Auto Feedback Control Circuits. Capable to adjust input and
output automatically for constant voltage
• Automatic Line Drop Compensation
• Fixed voltage Fixed current. Interchangeable to have control
and protection features.
• Protection: Input Line Loop: Auto detection and trip for Over
Current, Over Voltage, Loss Phase, Phase Reversed.
Output Circuit: Electronic-controlled Short Circuit Protection.
400Hz Solid State Frequency Converter
FEATURES:
• Small, Light & Space Saving: Typically, 1/4 size of
motor-generator sets of the same power output rating.
• High Efciency, Optimum Stability, Superior Heat Dissipation.
• Economical Cost of Ownership.
• Modular design permits quick and easy replacement:
- Typical motor-generator sets downtime is four times greater,
often resulting in costly delays, maint. and production
schedules.
- High efciency features reduce operating costs through
25% and upward utility savings compared to motor-generator sets.
- On-site repairs are easily accomplished.
- Motor-generator sets quite often must be removed
from location for repairs, resulting in costly rigging and
transport charges.
• Low Noise: Solid State frequency converters have no moving
mechanical parts generating a loud noise and eliminates the
need for expensive sound insulation.
• Individual Phase Regulation at Output: Excellent voltage
regulation under 100% unbalanced load.
• Output Isolation Transformer: capable of sustaining CEMF
(counter-electromotive force).
• Option:
- 36VAC input voltage or acc. to customer’s
specications
- “Add on module” of Solid State frequency converter
and 28VDC power supply
• Low Harmonic Distortion at 3% maximum.
