Bently Nevada 3500/15 127610-01+125840-01 AC Power Supply Module

The Bently Nevada 3500/15 127610-01 + 125840-01 AC Power Supply Module is a key power component for the Bently Nevada 3500 Machinery Protection System. This dual part configuration combines two specific modules—127610-01, a Power Supply Interface Module (PIM), and 125840-01, an AC Power Supply unit—to deliver stable and reliable AC-to-DC conversion for the monitoring rack.

In high-availability industrial monitoring systems, consistent power is non-negotiable. These modules ensure the entire rack and connected transducers receive clean, regulated power, minimizing noise interference and preventing power-related faults. They are engineered to meet strict reliability requirements in applications like turbines, compressors, and critical process machinery. With built-in protections, redundancy support, and compliance with major international standards, they are designed to keep the 3500 system operating without interruption.

FAQ

1. What is the main role of the 127610-01 + 125840-01 modules?

   They convert incoming AC power into stable low-voltage DC and distribute it to the 3500 rack modules.

2. Can these modules be used together with a DC power supply module?

   Yes, the 3500 Series supports mixed AC and DC redundancy configurations.

3. How do the modules handle power failures?

   When used in redundancy mode, if one module fails, the other automatically takes over without interruption.

4. Does the AC Power Supply module have built-in overvoltage protection?

   Yes, it includes both overvoltage and overcurrent protection circuits.

5. Is the PIM (127610-01) required for all AC power supply installations?

   Yes, it serves as the interface between the AC module and the rack backplane.

6. What is the typical startup time after power is applied?

   Typically within milliseconds, ensuring fast system readiness.

7. Can this module operate under fluctuating input voltages?

   Yes, it is designed to handle a wide AC input range from 85–264 VAC.

8. Is any calibration needed after installation?

   No calibration is required; it operates immediately after installation.

9. How is the module mounted in the rack?

   It slides into the designated slot and connects directly to the backplane.

10. Can the module be replaced without shutting down the entire system?

    In redundancy setups, yes; otherwise, the rack should be powered down for replacement.
