Product Overview

• PN: 3500/15 127610-01
• Brand: Bently Nevada (Baker Hughes)
• Series: 3500 Turbomachinery Protection TSI System
• Type: General AC Input Main Power Supply Front Module

• Function: Core power conversion component exclusively installed on the dedicated left power slot of 3500/05 rack chassis. It accepts wide-range alternating current input, converts and distributes multi-channel stabilized voltage to the rack backplane, and powers all inserted monitoring, communication, display and rear I/O modules. Two units can be mounted for redundant backup; the standby power will automatically take over power supply once the main unit fails, avoiding system outage and protection interlock failure
