Structural Characteristics
- Standard subrack width module for HIQuad rack slot installation.
- Metal front panel fitted with LED fault indicators for each power branch.

- Metal shielding frame reduces electromagnetic interference.
Working Principle Main DC power from power supply module enters F7133 module. The module divides main power into multiple independent power branches for each rack slot. Each branch passes through dedicated fuse for overcurrent protection. Current sampling circuit monitors each branch current continuously. When fuse blows or branch power loss occurs, fault signal is sent to F7131 monitoring module and corresponding LED indicator activates. Single branch fault is isolated by fuse and will not interrupt power supply of other slots.
Installation Requirements
- Insert F7133 module into designated slot of HIQuad rack.
- Verify backplane connector contact reliability.
- Complete protective earth connection for module metal frame.
- Use specified fuse rating for each power branch.
- Perform branch power loss simulation test after installation.
- Verify communication link with F7131 module before rack commissioning.
Usage Notes
- Do not hot plug module when rack power remains active.
- Replace blown fuse only with fuse of same rated specification.
- Do not use fuse with higher current rating than original specification.
- Keep cabinet dry and free of corrosive gas and conductive dust.
- Check backplane connector tightness periodically under vibration environment.
- Do not modify internal power distribution circuit components.
- Replace module immediately when permanent hardware fault occurs.
