6RY1801-0AA02 Siemens Ebmpapst R2D225-RA26-11 Fan 3-phase 400V 180W
1.Overview of the 6RY1801-0AA02 Siemens Ebmpapst R2D225-RA26-11
The Siemens 6RY1801-0AA02 Ebmpapst R2D225-RA26-11 is a high-performance, single-phase, 24V DC / 2.5A industrial-grade switching power supply module from the SITOP PSU100C series. It is designed for automation control systems, machinery, and process industries requiring a highly reliable DC power supply.
The core value of this power supply module lies in its "ultra-reliable" design. It converts unstable AC grid voltage (ranging from 85 to 264 V AC) into a stable, pure, and precise 24V DC power supply, powering critical control components such as SIMATIC S7-1200/1500 PLCs, sensors, actuators, touch screens (HMIs), and small drives. Its high efficiency of 93.5% and extremely low no-load power consumption not only save energy but also reduce heat generation, improving long-term equipment reliability.
The 6RY1801-0AA02 offers excellent load and overload characteristics. It can deliver a full 2.5A current at ambient temperatures up to 60°C. In the event of a momentary overload, it can deliver a peak current of up to 4A (for up to 5 seconds), ensuring stable operation even for inrush loads such as contactors or small relays.

Key Features
Forced air cooling: Designed specifically for 6RA70/6RA80/6RY17 series DC speed controllers and SIMATIC DCP cabinets, ensuring a temperature rise of ≤35 K for key components such as thyristors and reactors under rated load.
Dual-frequency compatibility: Automatically adapts to 50 Hz/60 Hz, enabling plug-and-play compatibility with global power grids.
Status Monitoring: Built-in Hall effect sensors provide real-time speed pulse output; stall alarms can be connected to the "fan fault" input of a PLC/speed controller for remote shutdown protection.
Hot-swappable design: Flange and quick-connect terminals ensure replacement time of less than 1 minute without powering down the busbar.
Low noise and high reliability: Optimized impeller profiles reduce noise by 4 dB compared to the previous generation; ball bearing lifespan is 50,000 hours, with a maintenance interval of ≥5 years.
IP54 protection: Dust and oil mist resistant, suitable for harsh environments such as metallurgy, papermaking, and rubber extrusion.
