3300-12-01-20-01 PWA88219-01 Bently Nevada AC Power Supply Module

Q1: What is the Bently Nevada 3300/12-01-20-01 used for?

A1: The Bently Nevada 3300/12-01-20-01 Module supplies operating power for a Bently Nevada 3300 rack. Its job is straightforward—convert AC into a regulated DC voltage supply, then feed the rack and the 3300 proximity transducer system with stable power during normal operation.

Q2: Where is 3300/12-01-20-01 installed?

A2: Only one location is intended for it: Position 1 in the chassis. After installation, the PWA 88219-01 Power Supply sends power through the 3300 series backplane interface to the 3300/03 System Monitor, the 3300 Dual Vibration Monitor, the 3300/55 Dual Velocity Monitor, and other rack modules.

Q3: Can the input voltage for the 3300/12-01-20-01 be changed?

A3: Yes. Input voltage isn't locked to a single option. The jumper-selectable 115V/220V design lets maintenance personnel choose the appropriate setting for the local power supply, provided the correct fuse is installed at the same time.

Q4: Is the 3300/12-01-20-01 designed for harsh industrial sites?

A4: Around power plants and refineries, electrical noise is fairly common. An integrated line noise filter helps reduce that interference, while the coated circuit board offers extra resistance to moisture and contamination. Because of that, the module is still found in power plant vibration monitoring, steam turbine safety protection, and gas turbine machinery monitoring applications.
