Cooling Fans for Transportation Equipment
Application-specific airflow for metro and high-speed rail electronics, marine power cabinets and aircraft auxiliary electronic modules.
From a compact onboard PCB to a large converter cabinet, the cooling configuration starts with the equipment: its power supply, available space, heat load and operating environment.
24 VDC and 48 VDC configurations, with a 230 VAC option in the reference list below.
Equipment applications
Airflow where transport electronics need it
Control, signaling & onboard power
Metro and high-speed rail applications in the reference list include control cabinets, traction controllers, signal and sensor boxes, door-control units and onboard PCBs. Locomotive auxiliary cabinets extend the range to larger enclosures.
Compact JF4028 and JF8025 configurations address localized electronic-module airflow, while JF12038, JF14038 and JF17251 configurations are listed for larger control assemblies. The JF17225-48L reference addresses metro HVAC inverter cooling.
Converters, UPS & electrical cabinets
Marine applications include electrical control boxes, converters, UPS systems, auxiliary equipment and engine-room power distribution boxes. The list spans 24 VDC and 48 VDC configurations and a 230 VAC JA12038HS2(7) option.
JF22580-24U and JF28080-48U are application references for high-power and main electrical control cabinets. Specify the exact installation environment and enclosure arrangement when reviewing these configurations.
Compact modules & auxiliary supplies
The supplied application list identifies JF4028-24M for aviation electronic modules, JF8025-24MM for aircraft onboard power supplies and JF8025-24M for auxiliary power-supply electronics.
Review available mounting space, supply characteristics, control interfaces and equipment qualification requirements for the intended module. These references describe cooling applications and do not establish aircraft installation approval.

Configuration review
Define the fan around the complete equipment
Electrical & control requirements
Share the nominal supply and operating range, target speed, wiring, connector and required monitoring or speed-control signals. Identify whether the fan serves a PCB, auxiliary power supply, inverter, converter or cabinet.
Airflow & installation
Provide the heat load, inlet-air temperature, available mounting envelope, airflow direction and system pressure requirement. Review the model drawing and fan curve for the exact configuration.
Environment & qualification
Specify the required IP rating, bearing arrangement, duty cycle, vibration, moisture and maintenance conditions. Include any rail, marine or aviation equipment qualification requirements in the engineering inquiry.
Discuss your transportation cooling requirements.
Send the equipment type, fan model, voltage, airflow, environment and expected quantity.
