ABB 3AXD50000045743 Fan kit

ABB 3AXD50000045743 fan kit detailed analysis

I. Product positioning and use

3AXD50000045743 is a fan kit designed by ABB for industrial automation equipment. It is mainly used for the cooling system of equipment such as inverters, servo drives or control cabinets. It reduces the temperature of internal components through forced air cooling to ensure stable operation of the equipment under high load conditions.

II. Technical characteristics and functions

Hardware composition

Fan body: usually contains 1-2 axial fans (the size may be 92mm×92mm×25mm or 120mm×120mm×38mm), using brushless DC motor (BLDC), long life (about 50,000 hours) and low noise (≤50dB).

Installation frame: metal or engineering plastic material, adapted to the heat dissipation holes of the equipment cabinet, supports screw fixing or buckle installation.

Connection harness: Contains power interface (such as DC 24V) and temperature control sensor interface, some models support speed monitoring or fault feedback.

Heat dissipation control logic

Temperature control start: built-in thermistor or temperature sensor, automatically starts the fan when the internal temperature of the device exceeds the threshold (such as 40℃), and delays shutdown after the temperature drops to avoid frequent start and stop.

Redundant design: Some kits contain dual fans in parallel. When a single fan fails, the other fan can still maintain basic heat dissipation to improve system reliability.

Protection and compatibility

Protection level: The fan mesh can prevent dust and debris from entering, and is suitable for industrial environments (such as inside IP20 cabinets);

Voltage compatibility: supports wide voltage input (DC 24V±10%), and is suitable for most industrial power supply systems.

III. Applicable equipment and scenarios

Typical compatible products:

ABB ACS800/ACS880 series inverters, ACQ580 series drives;

Cooling modules for industrial control cabinets, PLC control cabinets or servo system cabinets.

Application scenarios:

Equipment in high-temperature environments (such as metallurgical and chemical workshops) or high-load continuous operation requires forced heat dissipation to prevent overheating of components (such as IGBTs, capacitors, etc.);

In outdoor or dusty environments, use with dustproof nets to balance heat dissipation and protection needs.
