Backplane Bus Communication Velocity and Firmware Compatibility

The module supplies regulated 5.1 VDC power lines across the chassis backplane bus, sustaining the voltage stability needed to maintain high-speed backplane bus communication velocity during intensive CPU sweep intervals. Active power factor correction circuits minimize harmonic distortion across the input lines. Internal logic monitors the power rails, signaling early status alerts to the host controller prior to the expiration of the 21 ms ride-through window, enabling safe processor state preservation and firmware flash compatibility interlocks.

Frequently Asked Questions

Q: How does the overvoltage and overcurrent protection behave during a field fault?

A: The module utilizes non-destructive electronic clamping circuits. If the 5.1 VDC rail climbs to 6.2 V, the overvoltage loop clamps the output. Under overcurrent states approaching 12 A, the output voltage drops automatically. Both mechanisms protect the internal power supply fuse from opening, recovering to nominal values immediately after the field load anomaly is removed.

Q: Can this power supply module drive multiple racks simultaneously?

A: Yes. It can drive a secondary expansion rack through specialized extension cables (IC697CBL700 / IC697CBL713) provided that the auxiliary chassis requires only 5 VDC logic power and the combined current demands of both racks remain within the 56 W maximum output thresholds.

Field Installation Guidelines

  • Mechanical Placement: Slide the module into the leftmost slot of an authorized IC697 rack frame or a VME integrator rack. Ensure that the module's backplane connector aligns perfectly before locking it into position.
  • Grounding Configuration: Connect a dedicated AWG #12 (3.3 mm2) copper grounding conductor to the module's front ground screw terminal. Tighten the wire lug screw to a maximum torque rating of 12 in-lb (1.3 N-m).
  • Wiring Requirements: Use only copper supply conductors rated for a minimum temperature of 75 deg C. Route the incoming high-voltage AC or DC lines inside separate conduits away from sensitive low-level analog or communication cables.
