Backplane Bus Communication and Firmware Compatibility

The module interfaces directly with the PACSystems RX3i backplane bus, supporting high-speed deterministic data exchange and status monitoring across connected CPU and I/O modules. Firmware flash compatibility ensures that system updates can be deployed directly through the programming environment without requiring hardware replacement. Multiple power supply modules can operate in parallel on a single backplane to provide load sharing and redundancy, maintaining stable bus voltage levels during high-current transient states.

Frequently Asked Questions

Q: What is the maximum number of power supplies supported in a single RX3i rack?

A: Up to four power supplies can be installed in a single rack to support high-density configurations and load sharing.

Q: How does the module handle input power interruptions?

A: It provides a ride-through time of 20 milliseconds during a power failure to maintain reliable output states before shutdown.

Field Installation Guidelines

Ensure the rack is powered off before inserting or removing the power supply module. Mount the module securely into two designated backplane slots, locking the top and bottom latches to ensure proper mechanical and electrical seating. Connect the AC or DC power source to the terminal block in accordance with local electrical codes, ensuring proper earth grounding to the chassis ground stud to protect against surge voltages and electrical noise.
