Description

The Siemens SITOP TR-500Q-P-F1 3503311-02 is a high-efficiency, industrial-grade DIN-rail power supply engineered for mission-critical automation systems. Part of Siemens’ premium SITOP PSU5000 series, this 24VDC/20A unit delivers 480W of stabilized power with exceptional reliability and advanced protective functions. Designed for global deployment, the TR-500Q-P-F1 accepts wide-range AC input (85–264VAC) and features active power factor correction (PFC >0.95), reducing harmonic distortion and energy costs. Its core innovation lies in the integrated “F1” class electromagnetic compatibility (EMC) filtering, exceeding EN 55011 standards to prevent interference with sensitive PLCs, drives, or measurement devices. The ruggedized metal housing (IP20) incorporates convection cooling with derating-free operation up to 60°C, making it ideal for densely packed control cabinets. As the backbone of Siemens’ SIMATIC S7-1500 and ET 200SP ecosystems, this power supply ensures zero-voltage drop during brief mains failures (<20ms>

Technical Specifications

Main Features and Advantages

Ultra-Robust Power Delivery: The TR-500Q-P-F1 utilizes synchronous rectification and SiC MOSFETs to achieve 94% efficiency, reducing heat dissipation by 30% compared to conventional designs. Its “F1” EMI filter eliminates the need for external filters, suppressing both differential and common-mode noise to <1mV>

Intelligent System Integration: A green “DC OK” relay contact provides remote monitoring capability, while the “Ready” contact signals operational status to PLCs. The power supply supports parallel operation with active current sharing (up to 3 units) for N+1 redundancy. Backed by Siemens’ SITOP Manager software, it enables predictive maintenance through runtime logging and temperature trend analysis.

Deployment Flexibility: With universal input (85–264VAC/120–370VDC), the same unit deploys globally without hardware changes. Conformal coating (optional) protects against humidity and corrosive atmospheres. The integrated DIN rail latch allows tool-less installation, and front-facing terminals simplify wiring.

Application Field

The Siemens TR-500Q-P-F1 powers stability-sensitive automation:

Factory Automation: Primary PSU for SIMATIC S7-1500 PLC racks, SINAMICS G120X drives, and ET 200SP remote I/O stations in automotive assembly lines.

Process Control: Uninterrupted 24VDC supply for burner management systems in oil refineries, leveraging holdup time during grid dips.

Semiconductor Fabs: Clean power for wafer handling robots where EMI suppression prevents sensor false triggers.

Material Handling: Powers motor starters and safety relays in conveyor systems, with overload resilience against motor inrush currents.

Renewable Energy: DC source for SCADA controllers in wind turbine nacelles, operating at -25°C without heaters.

Installation and Maintenance

Pre-installation preparation: Verify DIN rail (EN 60715) strength and cabinet ambient temperature. Ensure minimum 50mm clearance above/below the TR-500Q-P-F1 for airflow. Tighten AC/DC terminals to 1.2 N·m using copper conductors (min. 14 AWG). Ground the unit directly to cabinet earth (≤0.1Ω).

Maintenance recommendations: Monitor “DC OK” LED monthly; replace if flickering occurs under load. Clean ventilation slots annually with dry air (<0>
