51303940-250 | Honeywell | Cabinet Fan With Alarm

Honeywell 51303940-250 is a cabinet fan with alarm function, mainly used for heat dissipation and temperature monitoring of industrial cabinets, control cabinets and other equipment. The following is a detailed description of the common characteristics of industrial fans and Honeywell product features:

Core Functions

Heat Dissipation and Ventilation

The fan blades are driven by high-efficiency motors to provide stable air volume, help the equipment in the cabinet to dissipate heat, and prevent equipment failure or performance degradation due to excessive temperature.

The fan speed may support automatic adjustment, dynamically adjust according to the temperature changes in the cabinet, and take into account both heat dissipation efficiency and energy consumption control.

Temperature Alarm Function

The built-in temperature sensor monitors the temperature in the cabinet in real time. When the temperature exceeds the preset threshold, the alarm mechanism (such as sound and light alarm, relay signal output, etc.) is triggered to remind the operator to deal with the heat dissipation abnormality in time.

The alarm threshold can usually be customized through the knob or external interface to meet the heat dissipation requirements of different equipment.

Industrial-grade reliability design

The shell is made of high-temperature and corrosion-resistant materials (such as metal or high-strength engineering plastics), with dust and splash-proof capabilities, and is suitable for dust, moisture and other scenes in industrial environments (may meet IP54 and other protection levels).

The fan bearing may adopt a long-term design (such as ball bearings), support long-term continuous operation, and reduce maintenance frequency.

Alarm signal output

Supports multiple alarm interfaces, such as dry contact output (relay contact), LED indicator alarm, and can be linked with PLC, monitoring system or host computer to achieve remote monitoring and fault warning.

Technical parameter speculation

Fan size: It may be adapted to standard cabinet installation holes (such as 1U, 2U height), and the blade diameter is about 120mm~140mm (common industrial fan specifications).

Air volume and speed: The air volume is about 200~400 cubic meters/hour, and the speed is automatically adjusted according to the temperature (such as 800~2000 rpm).

Power supply specifications: Support AC 220V or DC 24V power supply (common voltage in industrial scenarios), power is about 10~30W.

Alarm threshold range: The temperature alarm point can be set (such as 40℃~60℃), and the specific range is subject to the product manual.

Application scenarios

Industrial control cabinet/PLC cabinet: dissipate heat for inverters, PLC modules, power supplies and other heat-generating devices to prevent control failure caused by high temperature.

Data center cabinet: assist server cabinet heat dissipation, combined with temperature alarm to ensure stable operation of IT equipment.

Automation equipment chassis: in scenarios such as CNC machine tools and robot control cabinets, maintain the operating temperature of internal components within a safe range.

Installation and maintenance

Installation method: supports cabinet side panel, back panel or top installation, fixed by screws to ensure smooth ventilation path.

Maintenance points: regularly clean the dust on the fan blades and air inlet to avoid dust accumulation affecting the heat dissipation efficiency; check whether the alarm function is normal to ensure timely response when the temperature is abnormal.
