Catalog data confirm for code 9293510514 / 4414/2H a 24 V DC supply, 4300 rpm, 8.6 W, 4 m³/min, 160 Pa, 50 dB(A), ball bearings, and a 3-wire connection with tachometer.
🔌 Electrical Connections
The label clearly shows the three-conductor configuration:
-
RD / Red = +UB, positive power supply;
-
BU / Blue = GND, negative/power supply;
-
WH / White = Tacho, tachometric signal.
The third wire therefore allows the fan to be used in systems equipped with speed control or rotation detection, a particularly useful function in inverters and industrial equipment where correct ventilation operation must be monitored. Commercial documentation identifies the model as a 3-wire version with tachometer.
⚡ Function in the Electrical System
The main function of the 4414/2H is to provide forced cooling for electronic and power components.
The airflow of approximately 4 m³/min allows heat generated during operation to be removed from:
- photovoltaic inverters;
- DC/DC and AC/DC converters;
- industrial power supplies;
- electrical panels;
- power electronic systems;
- industrial automation equipment;
- electrical cabinets and electronic cooling systems.
The Tacho signal can be used by the control electronics to verify that the fan is actually rotating. Failure to detect the speed can therefore be used as an alarm or equipment protection condition.
🔧 Faults, Errors and Symptoms
Fan wear or malfunction may cause:
-
increased internal equipment temperature;
- temperature alarms;
- reduced inverter or electronics performance;
- shutdowns due to overtemperature;
- fan failure to start;
- irregular rotation;
- abnormal bearing noise;
- vibrations;
- reduced airflow;
- loss or abnormality of the tachometric signal;
- intermittent shutdown during operation.
The presence of a stopped fan does not necessarily mean that the motor is faulty: 24 V DC power supply, wiring, connector, control circuit, and Tacho signal must also be checked.
🏭 Construction and Product Condition
The photographed fan is used and shows normal signs of previous use and handling.
The frame and blades appear intact, with no evident structural breaks in the photographs. The three original conductors with free ends are present, as visible in the images.
🌐 Applications
The ebm-papst 4414/2H is particularly suitable for:
-
photovoltaic inverters;
- industrial inverters;
- power converters;
- power supplies;
- electrical panels;
- electronic equipment;
- automation systems;
- electrical cabinets with forced cooling;
- industrial systems requiring continuous ventilation.
The compact dimensions 119 × 119 × 38 mm and 24 V DC power supply make it suitable for replacing equivalent industrial fans, always checking dimensions, voltage, current, airflow, pressure, and Tacho signal configuration.
🛡️ Safety and Installation
Installation must be carried out with the equipment disconnected from the power supply.
The polarity indicated on the label must be respected:
red = +24 V DC, blue = GND, white = Tacho.
The fan must be installed with adequate fastening and sufficient space to allow proper airflow. No foreign objects should be present that could enter the blades during operation.
📦 Package Contents
