## Description

The R3G133-RA01-03 is an advanced EC centrifugal fan utilizing backward-curved blade technology within a single-inlet RadiCal housing configuration. Engineered for high-efficiency thermal management, this 133 mm blower operates from a nominal 230 VAC (50/60 Hz) single-phase AC supply voltage, drawing a maximum current of 0.27 A with a power consumption of 27 W. The unit delivers a maximum volumetric air flow of 165 CFM (280 m³/h) and achieves robust static pressure performance suitable for densely packed electronic enclosures and demanding forced-air cooling systems. Constructed with a die-cast aluminium electronics housing, a durable 7-blade PA plastic impeller, and reliable ball bearings, the assembly weighs 0.5 kg and features an IP54 ingress protection rating for dependable operation in harsh industrial environments.

This EC centrifugal blower integrates a sophisticated electronic control interface safely separated from the mains via SELV potential, supporting 0–10 VDC or PWM speed control inputs, an isolated open-collector tachometer output providing one pulse per revolution, and a 10 VDC auxiliary voltage output (max 1.1 mA). Comprehensive internal motor protection features include locked-rotor protection, soft start functionality, over-voltage and line undervoltage detection, and over-temperature protection for both the motor and integrated electronics. Electrical connections are handled via seven discrete lead wires configured for AC power supply (L, N, PE) and control/monitoring signals. 

Designed for continuous S1 operation across an ambient temperature range of -25 °C to +60 °C, the R3G133-RA01-03 complies with EN 60335-1 safety standards and meets EN 61000-6-2 industrial immunity and EN 61000-6-3 household emission requirements for electromagnetic compatibility. Its versatile mounting position and robust construction make it exceptionally well-suited for ventilation, HVAC units, electronic cabinet cooling, and industrial automation equipment requiring precise airflow modulation and high reliability.
