Key Features

1. Centralized Power Distribution: Distributes regulated 125 VDC power to all Mark V system cores, I/O boards, and auxiliary components, ensuring consistent voltage levels across the control system.
2. Comprehensive Overcurrent Protection: Equipped with 36 individual fast-acting fuses, each protecting a specific circuit, preventing cascading failures from short circuits or overloads.
3. Real-Time Status Monitoring: Features 36 green “OK” LEDs, each illuminating to confirm its corresponding fuse is intact and power is active, enabling immediate visual fault detection.
4. Flexible System Configuration: Includes 8 DIP toggle switches that allow operators to independently enable or disable individual control cores during maintenance or system reconfiguration.
5. Integrated Signal Routing: Provides 4 dedicated signal terminals for routing critical I/O signals between the power distribution board and other system modules, simplifying cabinet wiring.
6. Robust Industrial Design: Constructed with high-temperature, vibration-resistant components and conformal coating, ensuring reliable operation in harsh environments with electrical noise and temperature fluctuations.
7. Seamless Mark V Integration: Designed as a direct-fit replacement for Mark V systems, supporting plug-and-play installation without requiring system reconfiguration.
