ABB RXTUG22H 1MRK000592-A Power module

Product Identification

• Model Number: RXTUG22H

• Product ID / Part Number: 1MRK000592-A

• Product Type: DC/DC Power Supply Module (Auxiliary Power Converter)

• Product Family: COMBIFLEX Modular Relay System / Protection and Control Range

Technical Specifications

• Core Functionality: Operates as a highly isolated DC/DC converter within the COMBIFLEX relay matrix. It accepts a wide auxiliary DC input from the station battery bank and converts it into a regulated, low-noise secondary DC voltage required to power internal electronics, measurement circuits, and trip logic units.

• Input Voltage Range: Designed to accommodate standard utility substation auxiliary battery supplies, typically featuring a wide tolerance range to handle battery charging and discharging drops (e.g., matching standard networks like 110V-250V DC depending on internal jumper configuration).

• Output Configuration: Delivers precise, dual-rail or specialized low-voltage DC logic outputs ($+$24 V DC or similar stabilized rails) to power adjacent COMBIFLEX protection and measuring relays.

• Galvanic Isolation: Features high-grade test-voltage insulation between the primary input, secondary output, and ground circuits, ensuring that high-voltage line surges or ground faults do not damage delicate electronic logic.

• Form Factor & Mounting: Built specifically to plug into a standard COMBIFLEX seat or terminal base rack (often taking up a specific number of module seats, typically designated in COMBIFLEX “C” or “U” space dimensions).

• Onboard Diagnostics: Outfitted with front-panel LED indicators to verify output voltage health, along with internal monitoring circuitry that can trip an auxiliary alarm contact if output voltage drops below operating thresholds.

Target Industries

The RXTUG22H power module is primarily deployed in infrastructure and power grid automation sectors:

• Power Generation Utilities: Installed in thermal, hydro, nuclear, and wind generation facilities within the main generator protection panels.

• Electrical Transmission & Distribution: Stationed inside high-voltage (HV) and medium-voltage (MV) electrical substations.

• Heavy Rail & Infrastructure: Used in traction substations that supply power to electric rail systems and mass transit networks.

• Heavy Process Industries: Found inside the electrical distribution centers of large-scale plants like steel mills, chemical facilities, and refineries.

Applications and Use Cases

• COMBIFLEX Relay Rack Supply: Serves as the central, dedicated auxiliary power source for a cluster of plug-in COMBIFLEX protection modules (such as overcurrent, differential, or distance relays).

• Substation Battery Conditioning: Filters out electrical noise, ripples, and voltage spikes originating from the substation’s primary DC battery charger network, providing clean power to microprocessor-based relays.

• Trip Logic and Interlock Energization: Provides the highly reliable power reservoir necessary to actuate trip circuits and breaker interlocking schemes during critical grid fault conditions.

• System Retrofitting and Lifecycle Support: Deployed as a direct-fit replacement component during substation modernization programs to sustain legacy COMBIFLEX protective relay assemblies without overhauling the existing panel wiring.
