Description
Bently‑Nevada 3500/15 133292‑01 Low‑Voltage DC Power Supply Module
Product Overview
133292‑01 is legacy low‑voltage DC main power module for 3500/15 power supply system, must work together with rear PIM daughter‑board 133300‑01(Low‑Voltage DC Power Input Module)Baker Hugh…. It accepts nominal 24 VDC field battery power, converts to multi‑rail regulated DC for 3500 rack backplane. Supports 1+1 hot‑swap redundant configuration; single module can power full complete rack. OEM production discontinued, available only as aftermarket spare for legacy turbine/compressor TSI racks。

Core Features
- 24 VDC nominal field‑battery input: 20‑30 VDC wide DC input, designed for plant 24V battery backup power system.
- 1+1 hot‑swap redundancy: Two power‑supply modules can run parallel hot‑backup; remove one unit without rack shutdown when second healthy supply exists. AC‑DC mixed redundant configuration allowed in same rack.
- Multi‑rail regulated DC outputs: Provides all required backplane DC voltages for every monitor, RIM and communication module inside 3500 rack.
- Complete multi‑fault protection suite: Automatically shuts down upon over‑voltage, short‑circuit or over‑temperature to protect downstream monitoring hardware.
- System‑level power‑fault diagnostics: Local front‑panel OK‑LED indicator; power‑failure alarm event transmitted to RIM for host monitoring‑software logging.
Main Functions
- Receives 24 VDC station battery power through rear‑side 133300‑01 PIM input module, converts DC input into multiple regulated DC power rails feeding 3500 rack backplane.
- Supplies stable working power for RIM, keyphasor, vibration‑monitor and communication modules for entire rack.
- Supports hot‑swap maintenance for redundant‑configured racks; allows module replacement without machinery‑protection system shutdown.
- Detects internal power‑supply faults and reports power‑failure diagnostic events to rack‑interface‑module for system‑level alarming and event‑history storage.
