Power Management & Fault Isolation
- The chassis integrates independent overcurrent protection fuses for each power distribution channel (+5 V DC and +24 V DC), with 2 A fast-blow fuses for +5 V DC and 5 A slow-blow fuses for +24 V DC. Each fuse is replaceable via front-access fuse holders, eliminating the need to disassemble the chassis for fuse replacement and reducing maintenance downtime.
- Built-in power supply fault detection circuits monitor the voltage and current of each power channel in real time, and transmit fault signals to the central CPU via the backplane bus. The CPU can trigger alarm prompts or emergency shutdown procedures according to the fault level, realizing intelligent power fault management.
- The signal bus and power bus of the chassis are physically separated and independently shielded, and each module slot is equipped with independent power isolation diodes to prevent reverse current caused by module failure from affecting other modules and the entire backplane bus, achieving slot-level fault isolation.
