Backplane Bus Communication Velocity & Power Distribution
The IC697PWR724 module features dedicated internal power conversion circuitry tailored for high-density Series 90-70 backplane configurations. It delivers regulated +5 VDC logic power alongside auxiliary +12 VDC and -12 VDC rails to feed input/output circuits and processing cards across the backplane bus. System firmware flash compatibility and deterministic backplane communication velocity across the VME architecture rely on low-ripple output voltages during transient load demands. The internal power stage incorporates a controlled input inrush energy circuit rated up to 22 J to mitigate voltage sag on the primary 24 VDC feeder bus during initial system energization.
Frequently Asked Questions
Q: Can the IC697PWR724 module supply power to expansion racks in a Series 90-70 system?
A: Yes, the IC697PWR724 can provide power to a second rack in single or expansion configurations, provided the combined power drain across all connected rails does not exceed the maximum output limit of 90 Watts.
Q: What is the behavior of the supply during short primary power interruptions?
A: The module maintains a minimum ride-through time of 10 ms under full load conditions, permitting execution of hold-up functions before system power failure logic triggers.
Q: Is hot-swapping permitted for the IC697PWR724 module during backplane operation?
A: No, primary 24 VDC input power must be isolated and the backplane de-energized prior to inserting or removing the power supply module to prevent electrical arcing and backplane bus signal corruption.
Field Installation Guidelines
- Verify that incoming DC power wires are de-energized and tagged out prior to terminal connection. Ensure the supply line voltage remains strictly within the specified 18 to 32 VDC window.
- Align the module card edges with the designated rack slot guides of the Series 90-70 chassis. Slide the module firmly into place until the backplane connectors seat completely.
- Tighten the top and bottom retaining screws to secure the chassis ground bond and prevent physical displacement due to vibration.
- Wire primary 24 VDC input power using appropriate wire gauges, ensuring strict adherence to polarity and shield grounding standards to eliminate ground loops.
- Provide a minimum clearance of 50 mm above and below the rack chassis to ensure adequate convection airflow across thermal dissipation surfaces.
