M9204 Series

The M9204 is a series of mechanically robust, self-cooled (internal
fan), high performance, 3.2kW AC to DC power supplies, designed for
Navy shipboard applications. The M9204 converts MIL-STD-1399-
300B 3-Phase 440VAC (Delta) 60Hz shipboard power, to a well
regulated, filtered and protected DC Output.

• Complies with the User Interface Requirements of MIL-STD-1399-300B.
• Clean sine-wave input current – less than 3% harmonic current.
• Full-load Power Factor (PF) of above 0.98.
• Inrush current limiting.
• Inhibit Input, BIT and Current Monitor outputs.
• Overload, Overtemperature, Overvoltage and Missing-phase protections.
• Exceptional step-load response.
• Stable operation when loaded by large capacitance loads.
• Self-cooled unit - cooling air is confined to a close-channel heatsink.
• An RPM controlled cooling-fan ensures longer life and higher reliability.
• Full galvanic isolation between Input, Chassis and Outputs.
• Withstands MIL-STD-1399-300B 2,500 V spikes.
• Complies with MIL-STD-461G for shipboard application.
• Complies with MIL-STD-167-1 (Type I) shipboard vibration.
• Robust mechanical design, intended for systems that should withstand
  MIL-DTL-901E high impact shocks.
• Up to 5 (five) identical M9204 unis can be connected in parallel (current
  share) and provide up to 16KW of regulated and protected power.
• Less than 1/5th of the Human Body Leakage limits of MIL-STD-1399-300B, allowing safe parallel connection of up to five M9204 units.
• J-STD-001B and IPC-610A Class-3 workmanship. Conformal Coating per MIL-I-46058C and IPC-CC-830.
