Industrial Multi-Channel Power Controller Board | Fused Output Distribution | DC/DC Regulated | Version 1


Description

Custom-designed industrial-grade multi-channel power controller board engineered for robust DC load management and power distribution in demanding environments. This large-format red solder mask PCB features an extensive array of fused high-current output channels (F1–F23+), dual battery input support (Batt1+, In Batt2+), and on-board DC/DC conversion — delivering reliable, protected power to dozens of downstream loads simultaneously.

The board integrates a microcontroller-based control system with a dedicated diagnostic header for real-time system monitoring, fault detection, and field debugging. Over 40+ individually addressed output connectors (FH1–FH49) provide flexible wiring to relays, solenoids, actuators, sensors, and other industrial peripherals. Multiple automotive/industrial-grade blade fuses protect each output channel against overcurrent and short-circuit faults.
