RXTUG 22H 1MRK000592‑A

1. Product Title

ABB RXTUG 22H 1MRK000592‑A‑ Galvanically‑Isolated DC‑DC Converter Module

2. Product Overview

RXTUG 22H, part number 1MRK000592‑A, is ABB DC‑DC converter module designed for protection relay and substation automation IED auxiliary power supply. It accepts wide‑range DC input 24‑250 VDC, provides stabilized, galvanically‑isolated DC output. Continuous output power reaches 15 W, short‑time peak power up to 20 W. Input‑to‑output galvanic isolation suppresses ground loop interference and transient voltage surges from substation DC power networks. Reverse‑polarity input protection prevents module damage during field wiring errors. Compact plug‑in form factor fits inside ABB protection relay cabinets, widely used as maintenance spare for power‑plant and substation protection IED systems.
