Product Introduction: 3500/20 125760-01
The 3500/20 125760-01 is a Power Supply Module for the Bently Nevada 3500 Machinery Protection System. This module is a fundamental component responsible for converting the incoming AC or DC plant power to the precise, regulated DC voltages required by all the monitoring and relay modules within the 3500 rack. It provides the necessary +15V, -15V, and +5V DC power via the rack's backplane. Designed for high reliability in industrial environments, this power supply ensures the continuous operation of the entire protection system, which is critical for safeguarding valuable machinery from damage.
