GE / Bently Nevada 3300/10-01-02-00-00 Power Supply

The GE / Bently Nevada 3300/10-01-02-00-00 is a regulated DC power supply module for Bently Nevada 3300 series machinery monitoring systems. It converts AC input to programmable DC output, powering up to 12 monitors and 1–36 measurement channels in rotating machinery protection applications. The unit installs in position 1 (leftmost) of a 3300 rack as a double-wide module and includes integral line noise filtering, field-selectable input voltage, and an OK relay for system status annunciation.
