🔧 Main Functions
The fan is designed to create a continuous airflow to dissipate the heat generated by electronic components during operation.
It is particularly suitable for cooling:
- photovoltaic inverters;
- industrial power supplies;
- electronic equipment;
- electrical panels;
- automation systems;
- telecommunications equipment;
- power conversion and power systems.
🔌 Purpose and Operation
The fan is powered directly by 24 V DC and uses a brushless motor to drive the rotor and generate airflow.
With a stated airflow of approximately 107 CFM, it is designed for applications where effective heat dissipation from electronic components is required.
🧩 Compatibility
The identified model is:
SUNON KD2412PMS1-6A
Compatibility with a specific inverter or piece of equipment must be verified by comparing:
- fan model;
-
24 V DC voltage;
-
120 × 120 × 38 mm dimensions;
- connection type;
- wiring length and configuration;
- airflow direction;
- mounting system.
⚠️ Typical Faults and Symptoms
A faulty or worn fan may cause:
- no rotation;
- slow or irregular rotation;
- abnormal noise;
- vibrations;
- insufficient airflow;
- increased internal equipment temperature;
- activation of thermal protections;
- inverter or power supply shutdown due to overheating.
🔍 Diagnosis
The fan can be checked by verifying:
- presence of the 24 V DC supply;
- current consumption;
- motor startup;
- regularity of rotation;
- any abnormal noise or vibration;
- possible mechanical rotor blockage;
- wiring and connection condition.
A fan receiving the correct voltage but failing to start may have a motor or internal electronic fault.
🛠️ Common Services in Case of Failure
- Electrical fan inspection.
- Power supply verification.
- Current consumption check.
- Cleaning of dust and residues.
- Rotor inspection.
- Complete fan replacement in case of failure.
🛠️ Applications
Cooling fan for electronic and industrial equipment, particularly suitable for systems requiring 24 V DC power supply and high airflow.
It can be used as a replacement for ventilation systems installed in photovoltaic inverters, power supplies, electrical panels and power equipment, subject to verification of mechanical and electrical compatibility.
