125760-01 rack power supply module

The BENTLY 125760-01 is a rack power supply module dedicated to Bently Nevada’s 3500 Series Rotating Machinery Protection & Monitoring System. As a core power component for the 3500 series racks, it provides stable and reliable DC power to all functional modules installed in the rack (e.g., vibration monitors, speed modules, Keyphasor modules) while supporting redundancy configurations to ensure uninterrupted operation of the monitoring system. This module is widely used in industrial scenarios requiring high power stability, such as power plants, petrochemical refineries, and metallurgical plants, where the reliability of rotating machinery monitoring directly affects production safety. Below is its comprehensive detailed information:

I. Core Technical Parameters

Category	Specific Specifications
Basic Identification	- Model: 125760-01- Product Type: Rack Power Supply Module (for BENTLY 3500 Series)- Applicable Rack: Compatible with BENTLY 3500/10 single-frame racks and 3500/20 multi-frame racks- Core Role: Converts AC input to regulated DC power for powering 3500 series functional modules; supports redundancy to prevent power-related system downtime
Power Input & Output	- Input Voltage: 100-240 V AC (wide-range input, 50/60 Hz, compatible with global industrial power grids)- Input Current: 3 A (max, at 100 V AC); 1.5 A (max, at 240 V AC)- Output Voltage: +24 V DC (regulated, precision ±0.5 V, ensuring stable power for sensitive modules like 16-bit ADC-based monitors)- Output Current: 5 A (continuous); 7 A (peak, for short-term high-power demands during module startup)- Power Conversion Efficiency: ≥85% (high efficiency reduces heat generation, extending module lifespan)
Redundancy & Protection	- Redundancy Support: Designed for 1+1 redundancy configuration (two 125760-01 modules share the load in parallel). If one module fails, the other automatically takes over full load (switchover time <10 ms) to avoid power interruption.- Protection Functions:- Overvoltage Protection (OVP): Triggers at +28 V DC to prevent damage to downstream modules from voltage spikes.- Overcurrent Protection (OCP): Activates when output current exceeds 8 A (self-recovering after fault removal).- Over-temperature Protection (OTP): Shuts down temporarily if internal temperature exceeds +85°C (restarts when cooled to +70°C).- Short-Circuit Protection (SCP): Instantly cuts off output in case of short circuits (avoids fire or permanent damage).
