Siemens 3RX9501-0BA00 Power Supply Unit for SIRIUS 3RF Solid-State Relays

Industrial Automation Power Solution – Siemens 3RX9501-0BA00 | SIRIUS 3RF Series

In demanding industrial environments — from automotive assembly lines to chemical processing plants — solid-state relays must operate with zero tolerance for power instability. The Siemens 3RX9501-0BA00 is the dedicated auxiliary power supply unit engineered specifically for the SIRIUS 3RF series of solid-state relays, ensuring clean, regulated 24 VDC control power that keeps your switching devices performing at specification, shift after shift.

Without a properly matched power supply, even the most advanced solid-state relay becomes a liability — susceptible to nuisance tripping, thermal runaway, or premature failure. The 3RX9501-0BA00 eliminates that risk by delivering precisely conditioned auxiliary power, purpose-built for Siemens SIRIUS 3RF relay systems deployed across global industrial facilities.

Where This Product Is Used

The 3RX9501-0BA00 is specified by control engineers across a wide range of high-demand industrial sectors:

• Automotive Manufacturing: Body-in-white welding lines, paint shop conveyor drives, and press room motor control centers where SSR reliability is non-negotiable.
• Food & Beverage Processing: Hygienic zone heating control panels, pasteurization systems, and packaging line motor starters requiring stable auxiliary power.
• Plastics & Rubber Industry: Injection molding machine heater band control, extruder barrel temperature zones, and blow molding equipment.
• Chemical & Pharmaceutical Plants: Reactor temperature control loops, HVAC air handling units, and cleanroom environmental control systems.
• Building Automation & HVAC: Central chiller plant control panels, air handling unit motor starters, and BMS-integrated relay panels.
• Water & Wastewater Treatment: Pump station MCC panels, UV disinfection system controls, and aeration blower drive panels.

Why Engineers Specify This Model

• OEM-Matched Design: Engineered by Siemens specifically for SIRIUS 3RF relays — no compatibility guesswork, no field modification required.
• Stable Auxiliary Power: Delivers regulated 24 VDC to relay control circuits, preventing false triggering caused by voltage fluctuations on shared power rails.
• DIN Rail Integration: Snaps directly onto standard 35 mm DIN rail alongside SIRIUS 3RF devices, minimizing panel footprint and wiring complexity.
• Reduced Panel Engineering Time: Pre-validated for use with SIRIUS 3RF — eliminates the need for custom power supply sizing calculations.
• Long Service Life: Siemens industrial-grade components rated for continuous duty in harsh electrical environments.
• Global Compliance: CE marked and IEC/EN 60947-4-2 compliant, accepted by panel builders and end-users worldwide.
