Product introduction

The 125800-01 from Bently Nevada is a high-reliability power supply module engineered to provide stable, regulated power to critical machinery monitoring and protection systems. As a foundational component in both 3300 XL and 1900 series systems, this power supply converts AC line voltage to clean 24 VDC power, ensuring consistent operation of sensors, cables, controllers, and HMIs in industrial environments. Bently Nevada’s 125800-01 serves as the power backbone for monitoring systems, delivering reliable energy to components like the 330180-90-05 proximity sensors and 330108-91-05 extension cables, while maintaining the integrity of sensitive measurement equipment.

Bently Nevada’s 125800-01 addresses the critical need for stable power in precision monitoring applications, where voltage fluctuations can corrupt sensor data or cause system malfunctions. Its robust design and comprehensive protection features ensure uninterrupted operation even in harsh industrial environments, making it an essential component for maintaining the reliability of the entire monitoring chain—from sensor to controller to HMI. This power supply plays a vital role in preserving the accuracy of measurements calibrated by tools like the 330130-080-00-00, ensuring that protection systems have the consistent power required to function correctly.

Core advantages and technical highlights

Wide input range flexibility: The 125800-01 accepts 85-264 VAC input, making it suitable for global industrial applications with varying power grid specifications. This flexibility allows seamless integration into facilities worldwide without the need for voltage transformers, simplifying system deployment and standardizing power infrastructure across multi-location operations.

Stable regulated output: Delivering 24 VDC with ±1% voltage regulation, the 125800-01 provides the clean, consistent power required by sensitive components like the 330180-90-05 proximity sensors. Voltage stability is critical for maintaining measurement accuracy, as fluctuations can introduce noise into low-level sensor signals transmitted through 330108-91-05 cables, compromising data integrity.

Comprehensive protection mechanisms: The power supply incorporates multiple protection features—overvoltage, overcurrent, short circuit, and overtemperature protection—that prevent damage to connected equipment during fault conditions. This protection is particularly important for safeguarding expensive monitoring components and ensuring system availability during power anomalies.

High reliability design: With a mean time between failures (MTBF) exceeding 100,000 hours, the 125800-01 delivers the long-term reliability required in mission-critical monitoring applications. Its rugged construction and component selection ensure stable operation in industrial environments, reducing the risk of unplanned downtime due to power supply issues.

Typical application scenarios

In power generation facilities, the 125800-01 serves as the primary power source for turbine and generator monitoring systems, supplying clean power to 330180-90-05 sensors, 1900/27 controllers, and 1900/55-0Z-01-01-01 HMIs. Its ability to handle voltage fluctuations common in utility environments ensures continuous operation of vibration and position monitoring systems, which are critical for turbine protection and performance optimization. The power supply’s rack-mount design allows integration into standard control cabinets, simplifying system layout in turbine control rooms.

Oil and gas processing plants utilize the 125800-01 to power compressor and pump monitoring systems, providing reliable energy to sensors, signal conditioners, and communication modules. Its robust protection features safeguard against power surges and transients common in industrial facilities, ensuring uninterrupted operation of equipment that monitors critical rotating machinery. The power supply’s wide input range makes it suitable for installations in remote locations with less stable power grids.

Manufacturing facilities deploy the 125800-01 in production line monitoring systems, powering networks of 330180-90-05 sensors connected via 330108-91-05 cables. These systems monitor motor vibration, spindle position, and other critical parameters in real time, with the 125800-01 ensuring stable power delivery to maintain measurement accuracy. The power supply’s compact form factor allows installation in space-constrained factory control cabinets while delivering sufficient power for multi-sensor installations.

Installation, commissioning and maintenance instructions

Installation preparation: Before installing the 125800-01, verify that the input voltage matches the facility’s AC supply (85-264 VAC). Ensure the mounting location provides adequate ventilation and is within the 0°C to +50°C operating temperature range. Required tools include a screwdriver set, wire strippers, and a multimeter for voltage verification. Inspect the power supply for shipping damage, checking for loose components, damaged connectors, or visible signs of stress. Ensure the installation area is free from excessive dust, moisture, and vibration.

Commissioning procedures: After mounting the 125800-01 in the equipment rack, connect the AC input wiring following proper electrical safety protocols and ensuring correct phase and ground connections. Before connecting load devices, power on the supply and verify 24 VDC output using a calibrated multimeter. Once confirmed, connect the output to the monitoring system, ensuring polarity is correct to prevent damage to components like 330180-90-05 sensors. Perform a full system power-up test, verifying all connected devices receive stable power and operate correctly.

Maintenance suggestions: To ensure reliable operation of the 125800-01, conduct quarterly visual inspections to check for dust accumulation, loose connections, or signs of overheating (discoloration, unusual odors). Clean ventilation openings as needed to maintain proper airflow. Monitor output voltage periodically using a multimeter to ensure it remains within the ±1% regulation tolerance. Check input and output connections during scheduled maintenance to ensure secure fastening. In redundant configurations, test failover functionality annually to ensure proper operation during primary supply failure.
