Bently Nevada 3500 MOX12-P3509 Series External Power Supply Module

MOX12-P3509 is an external industrial power supply unit exclusively designed for Bently Nevada 3500 turbomachinery monitoring rack systems. It converts standard industrial AC input into stable multi-channel DC output to supply power for the full 3500 rack, including vibration monitoring cards, 3500/92 communication modules and signal conversion boards. The unit features built-in surge suppression and overcurrent protection to guarantee continuous power supply for critical rotating equipment safety monitoring.

This compact DIN-rail mounted power unit adopts wide-range AC input compatibility, suitable for power plant, petrochemical and metallurgical workshop unstable power grid environments. Equipped with multi-status LED diagnostic lights, it can quickly display overload, short-circuit and input power loss faults. As matching auxiliary hardware for the 3500 monitoring system, it is widely stocked as maintenance spare parts for global legacy turbomachinery protection racks.

Core Functions

• Stably convert industrial AC power into dedicated DC power to supply the entire Bently 3500 monitoring rack, supporting all vibration, displacement and temperature measurement modules.
• Multi-layer EMI filter circuit suppresses grid surge and electromagnetic interference from nearby inverters and high-voltage equipment to avoid signal distortion of sensor measuring chains.
• Multi-level safety protection logic automatically cuts off output when overload, short circuit or overheating occurs to prevent permanent damage to expensive 3500 series core monitoring boards.
• Front panel LED fault indicators directly display power supply abnormal status, enabling maintenance personnel to rapidly judge power failure causes without extra testing instruments.
• Wide input voltage tolerance adapts to unstable power supply conditions in power stations, chemical plants and mines, ensuring uninterrupted monitoring of gas turbines, compressors and large blowers.
• DIN rail compact design saves cabinet installation space, convenient for quick disassembly and replacement during on-site power supply fault maintenance.
