1. Product Title

ABB RXTUG 22H 1MRK000592‑A‑ DC‑DC Converter Power Module

2. Product Overview

RXTUG 22H 1MRK000592‑A is a DC‑DC converter module for ABB protection relays and substation automation systems. It accepts wide‑range DC input 24‑250 VDC and converts to stabilized isolated auxiliary output voltage, normally ±24 VDC. Continuous load capacity reaches 15 W with short‑time peak 20 W. Built‑in reverse‑polarity input protection and output‑failure alarm relay contact for remote fault signalling. Multiple units can be paralleled for redundant power configuration. Widely used to supply auxiliary working power for protection relays in power‑plant and utility substation control cabinets.
