Product Overview

086388‑001 is ABB rack‑mount industrial DC power‑supply module. It converts wide‑range AC mains input into stable 24 VDC output for control‑system I/O modules, field‑sensors and communication‑hardware inside automation cabinets. Multiple built‑in protection mechanisms improve system reliability under plant harsh‑grid‑condition. Widely used in power‑plant, petrochemical and manufacturing‑automation control‑cabinets. Surplus and refurbished tested spare power‑supply unit for cabinet‑maintenance and retrofit‑projects.

Application Notes

‑ Keep ventilation space around power‑module surface for convection heat dissipation. ‑ Do not exceed rated output‑current limit. ‑ Verify output DC voltage before connecting field‑load. ‑ Typical deployment: industrial‑control‑cabinet rack‑power‑supply spare‑part stocking.
