Technical Specifications:
  • Input: 18-36 V DC nominal 24 V DC
  • Outputs: +5 V, ±12 V, ±15 V, +28 V PSA (5 rails), +28 V remote (3 rails)
  • Continuous Power: 400 W
  • Isolation: 1500 V rms input-output
  • Indicators: Red (fault), Yellow (standby), Green (normal) LEDs + reset toggle
  • Dimensions: 233 × 169 × 47 mm, 0.9 kg
  • Operating Temperature: -40 °C to +70 °C
    Functional Features: Overcurrent/overvoltage/short-circuit auto-recovery, hot-swap capable, conformal-coated boards, low-voltage 24 V DC input for UPS/battery bus compatibility.
    Structural Characteristics: Standalone sheet-metal enclosed module, PSA/PSB harness connectors on side face, finned heatsink, natural convection cooling.
    Working Principle: 24 V DC input → DC-DC multi-rail conversion → regulated outputs through EMI filter and OR-ing diodes to VME backplane.
    Installation Requirements: Mount in dedicated LVPS slot of Mark VI rack, torque PSA/PSB screws to spec, ensure 24 V DC source is fused and grounded.
    Usage Notes: Do not mix with 125 V DC LVPS variants; verify green LED before turbine start; reset toggle clears latched faults only after cause removed.
