VM-12101 VME Power Supply Single Slot 250W [DC-DC]
VM-12101
  • Input Voltage 18 – 35 Vdc 
  • Operation to 16V for up to 1 second
    The unit is NOT reverse polarity protected
  • 17.3mm (0.68”) profile 
  • ACFAIL*, SYRESET* as per ANSI /VITA 1-1994. Recommended pull up to +5V via a 5Kohm resistance
  • 250W, 5V/30A, 3.3V/15A, ±12V/2.0A, 5V STANDBY/0.2A
  • Isolation:  Input to Output 50 Mohms@500Vdc
                           Input to Chassis 50 Mohms@500Vdc
                          Output to Chassis 10 Mohms@100Vdc
  • Current Share: These connections are used to permit paralleling of
    power supplies, 5V, 3V3 and ±12V only. Connect the respective share pins with an impedance of < 1ohm. Sharing is ± 10%
  • Efficiency: Not less than 78% (80% typically) for output power 50% max load at an input voltage of 28Vand at 25ºC baseplate temperature
  • 4ms minimum at full load and any input voltage within specified ranges. After 4ms (may be longer dependant on the load) all outputs apart from the 5V standby will shut down. 5V standby continues to provide power for a minimum of 300ms. Holdup Pins are provided for additional capacitance to increase the holdup time. Refer to factory for guidance in utilising this function
  • The units meet the following requirements of MIL-STD-461D CE101 (Figure CE101-4), CE102, CS101, CS114 (Curve #3), CS115, CS116 (Air Force)
  • Full specified performance with the card edge temperature maintained within the range –55ºC to +85ºC
  • Storage Temperature: -55ºC to +105ºC
