Product Introduction: 3500/15-03-03-01 Power Supply
The 3500/15-03-03-01 is a vital component within the Bently Nevada 3500 Machinery Protection System. It is a 125 VDC Power Supply module responsible for converting an external 125 VDC input into the regulated +15 VDC, -15 VDC, and +5 VDC power required by all the monitoring and relay modules within a 3500 rack. This model is specifically designed for applications where the primary control system or plant power source is a 125 VDC battery bank, a common standard in many industrial facilities for high reliability. It supports redundant (N+1) configuration, allowing a second power supply to be installed in the same rack to ensure continuous, uninterrupted operation of the critical machinery protection system, even in the event of a single power supply failure.

Application Scenarios
The 3500/15-03-03-01 is deployed in critical environments where system uptime is paramount and where 125 VDC is the standard for control and protection system power.
DC-Based Critical Control Systems:
Primarily used in facilities that utilize 125 VDC battery banks as a highly reliable power source for control and safety systems. This is common in power generation plants (nuclear, fossil fuel) and large petrochemical complexes.
High-Reliability Machinery Protection:
Serves as the primary or redundant power source for racks containing vibration monitors, torsional vibration monitors, speed modules, and relay modules, ensuring continuous protection for assets like turbines, compressors, and large pumps.
Uninterruptible Power Supply (UPS) Applications:
Ideal for integration with plant-wide DC UPS systems. During a loss of normal AC power, the 125 VDC battery bank continues to power the 3500 system without interruption, allowing for a controlled shutdown or continued operation of critical equipment.
Nuclear Power Plants:
Often specified in nuclear applications due to the stringent requirements for power supply reliability and the prevalent use of 125 VDC control power in such environments.
