Bently Nevada 125840-01 High Voltage AC Power Input Module
Manufacturer: Bently Nevada
Product Number: 125840-01
Category: High Voltage AC Power Input Module (3500/15 Vibration Monitoring System)
Input Voltage: 85-264 V AC, 47-63 Hz
Output Voltage: 24 V DC
Output Current: 10 A
Efficiency: >85%
Operating Temperature: -40°C to +70°C
Protection: Overvoltage, overcurrent, short circuit
Product Description
The Bently Nevada 125840-01 is a high-voltage AC power input module designed for the 3500 Series Machinery Protection System, specifically the 3500/15 Vibration Monitoring System. It delivers stable and reliable power to critical rotating machinery, ensuring continuous operation and early fault detection. This half-height module can be installed in one or two slots within the 3500 series rack, offering redundancy for enhanced system reliability. While no longer manufactured by Bently Nevada, it remains available through third-party suppliers for legacy systems.
Technical Specifications
| Parameter | Specification |
|---|---|
| Input Voltage Range | 175–250 VAC RMS |
| Output Voltage | 24 VDC |
| Output Current | 2 A |
| Operating Temperature | -30°C to +65°C |
| Storage Temperature | -40°C to +85°C |
| Humidity | 95% non-condensing |
| Weight | 1 kg |
| Dimensions | 8.5″ x 3.5″ x 0.75″ |
Advantages and Features
- Redundancy Support: Two modules can be installed for backup, minimizing downtime.
- Wide Voltage Tolerance: Accepts high-voltage AC inputs (175–250 VAC RMS), suitable for industrial environments.
- Overvoltage Protection: Fuse-based design safeguards against voltage spikes.
- Compact Design: Half-height form factor saves space in the 3500 series rack.
Application Fields and Cases
Industry Applications:
- Vibration monitoring in turbines, compressors, and pumps.
- Power generation, oil & gas, and manufacturing.
Case Study:
A chemical plant in India used the 125840-01 to power their 3500 system for reciprocating compressors. Its redundancy feature prevented system failures during voltage fluctuations, reducing unplanned outages by 25%.
Competitor Comparison
Compared to standard power modules:
- Higher Voltage Range: Supports up to 250 VAC vs. 240 VAC for most alternatives.
- Redundancy Flexibility: Allows dual-module configuration for critical systems.
- Robust Construction: Withstands extreme temperatures (-30°C to +65°C operation).
Selection Recommendations
- Compatibility: Ensure it matches your 3500 series rack configuration.
- Replacement Note: Consider the newer 106M 1079-01 Universal AC Power Supply Module for long-term support.
- Availability: Verify stock with suppliers, as this model is obsolete.
Precautions
- Installation: Mount in designated left-side slots of the 3500 rack.
- Maintenance: Replace fuses (part number 01720025) as needed. Avoid moisture and dust exposure.
- Safety: Power off the system before servicing. Use certified technicians for repairs.
