Half-height universal AC power supply for 3500 machinery protection rack, supports 85–264V wide AC input, allows 1+1 redundant hot-swap backup, supplies stable DC power to all monitoring modules, surplus spare parts for turbomachinery TSI system

Product Overview

• PN: 3500/15, Part No: 127610-01
• Brand: Bently Nevada (Baker Hughes)
• Series: 3500 Machinery Protection TSI System
• Type: Universal AC Input Power Supply Module

• Function: Half-height dedicated power unit mounted on the left power slot of all 3500/05 racks. Converts wide-range industrial AC input into multiple regulated internal DC voltages for backplane bus, vibration monitors, communication, relay and display modules. The rack supports two 3500/15 units for redundant backup; single unit can fully power a complete 14-slot rack without load loss.
