BENTLY 3500/15 127610-01 dedicated AC power supply module

The BENTLY 3500/15 127610-01 is a dedicated AC power supply module for Bently Nevada’s 3500 Series Rotating Machinery Protection & Monitoring System. As a core power component of the 3500 system, it provides stable and reliable DC power to other functional modules (e.g., vibration monitors, speed detectors, temperature modules) in the rack, ensuring the entire monitoring system operates continuously and stably in harsh industrial environments. Below is its comprehensive detailed information:

Protection Functions	- Overcurrent Protection: Automatically shuts down output when current exceeds 6A (prevents damage to the module and connected devices)- Overvoltage Protection: Triggers protection when output voltage exceeds +28V DC (avoids overvoltage damage to monitoring modules)- Overtemperature Protection: Activates when internal temperature exceeds +85°C (prevents module burnout due to overheating)

II. Core Functional Features

1. Stable & Reliable Power Supply

Wide Input Voltage Range: 85-264V AC input adapts to unstable power grids in industrial sites (e.g., voltage fluctuations in remote power plants) and global power standards (110V AC/220V AC), eliminating the need for additional voltage transformers.
Low Ripple Output: ≤50mV P-P ripple ensures no interference with weak signals from monitoring modules (e.g., eddy current sensor signals for vibration measurement), avoiding false alarms caused by power noise.

2. Comprehensive Protection Mechanisms

Multi-Level Fault Protection: Integrates overcurrent, overvoltage, and overtemperature protection. When an abnormal condition occurs (e.g., short circuit of a downstream module), the power supply module quickly cuts off the output to protect the entire 3500 system, and automatically recovers after the fault is resolved (or requires manual reset, configurable via software).
Surge Immunity: Withstands 1kV differential mode / 2kV common mode surge (per IEC 61000-4-5), resisting transient voltage impacts from industrial power grids (e.g., lightning-induced surges).

3. System Compatibility & Easy Maintenance

3500 Rack Integration: Designed for the 3500 system rack, it can be hot-swapped (inserted/removed while the rack is powered on) without interrupting the operation of other modules—critical for continuous monitoring of safety-critical equipment (e.g., turbines).
Status Monitoring: The front panel is equipped with two LED indicators:
- POWER (Green): Illuminates when the module is powered on and output is normal.
- FAULT (Red): Lights up when overcurrent, overvoltage, or overtemperature occurs, enabling on-site maintenance personnel to quickly identify power supply faults.

4. Energy Efficiency & Heat Management

High Conversion Efficiency: ≥85% efficiency reduces energy loss and heat generation, minimizing the need for additional cooling in the 3500 rack (suitable for high-temperature environments like turbine enclosures).
Optimized Heat Dissipation: Internal aluminum heat sinks and airflow channels ensure efficient heat dissipation, maintaining stable operation even at full load (5A output) in +60°C environments.
