The BENTLY 3500/15 127610-01 is a redundant rack power supply module for Bently Nevada’s 3500 Machinery Protection System, engineered to deliver ultra-reliable 24V DC power for critical monitoring hardware in high-risk industrial environments. Designed for continuous operation in safety instrumented systems (SIS), this dual-input module provides N+1 redundancy with automatic load sharing and failover, ensuring uninterrupted power to vibration monitors, PLCs, and safety relays. The BENTLY 3500/15 accepts 90–132V AC or 180–264V AC inputs (auto-sensing) with integrated active power factor correction (PFC >0.95), minimizing harmonic distortion per IEEE 519. Its convection-cooled design operates at -40°C to +70°C ambient temperatures with 6kV surge protection, making it ideal for offshore platforms, power plants, and compressor stations where power stability dictates operational safety.
Integrated diagnostics monitor input voltage, output current, and module temperature, relaying alarms to the 3500 framework via backplane communication. The BENTLY 3500/15 127610-01 features hot-swappable capability and complies with API 670 standards for machinery protection systems, providing galvanic isolation (>1500V AC) between input/output and chassis to prevent ground loops in electrically noisy environments.
