Product Description

Stable Low-Voltage DC Power for 3500 Monitoring Systems

The 3500/15-07-07-05 (Model: 3500/15) is a specialized Low Voltage DC power supply system designed for the Bently Nevada 3500 Series Machinery Protection System. This assembly, which includes the 133292-01 (High-Efficiency Power Supply Module) and the 133300-01 (Low Voltage DC Input I/O Module), provides regulated, noise-filtered power to all monitoring and communication cards within the 3500 rack. Engineered for industrial resilience, the 3500/15-07-07-05 (133292-01 + 133300-01) ensures that sensitive vibration and displacement data remains unaffected by input voltage fluctuations, maintaining the integrity of the critical protection loop.
