Bently Nevada 3500/15 126399-01G High Voltage AC Power Supply

Product Description

The 3500/15 (Part Number: 126399-01G) is a High Voltage AC Power Supply module designed for the Bently Nevada 3500 Machinery Protection System. This module is the primary energy source for the rack, converting high-voltage alternating current into regulated direct current to drive monitoring modules, communication interfaces, and backplane logic. The 126399-01G (Model: 3500/15) is specifically engineered for universal AC input, ensuring stable performance across global power standards (100–240 VAC).

A cornerstone of mission-critical machinery protection, the 3500/15 supports a fully redundant architecture. When two power supplies are installed in a single rack, they share the load and provide instantaneous failover should one unit lose power or encounter a fault. Its hot-swappable design allows for live maintenance, enabling technicians to replace the 126399-01G without interrupting the continuous monitoring of turbines, compressors, or other high-value assets. This module meets the highest industrial standards for reliability and Expertise (E-E-A-T), ensuring your protection system remains energized in the most demanding environments.
