Fans 7114NHRMotor 24V 19W 150x38mm case fan

SKU CH-1NB1-DBGHR MPN 7114NHRMotor

A 24 V axial case fan delivering 19 W at 3350 rpm with 150 × 38 mm dimensions for inverter and forced-air cooling

  • High airflow capacity with up to 35000 m³/h rating
  • Efficient 24 V operation drawing only 0.79 A current
  • Compact 150 x 38 mm frame fits tight spaces
  • Variable speed control via analog or serial interface
  • Durable steel plate construction for long service life

24 V 19 W axial fan for inverter cooling

This 24 V axial fan delivers 19 W motor power for inverter and industrial cooling. It suits engineers and technicians who need a direct replacement for ABB inverter airflow. Buyers who require a different voltage or a PWM-controlled PC case fan should look elsewhere.

GreenTech EC motor with analog or serial speed

GreenTech EC technology enables 100 % speed control via analog or serial interface. The motor runs at 3350 r/min drawing 0.79 A while maintaining low noise and high efficiency. The compact external-rotor design reduces installation depth in tight enclosures.

150 × 38 mm blade diameter and 35000 m³/h airflow

The 150 × 38 mm blade diameter moves up to 35000 m³/h through heat exchangers. Sturdy steel-plate construction ensures durability in forced-air cooling applications. Verify that your mounting pattern matches the 150 mm frame before ordering.

Questions about this item

How is the 150x38mm axial fan mounted in an ABB inverter and which step is often missed?

The fan uses the standard 150mm square frame with four corner holes; the step often missed is verifying the 24V supply polarity before applying power, because the 0.79A motor draws 19W and reverse voltage can damage the EC electronics.

What maintenance will the 7114NHRMotor need after extended operation?

The axial design has sealed ball bearings and no user-serviceable parts; plan only periodic dust removal from the blades and frame to keep airflow near the 3350 r/min rating, and replace the unit if bearing noise appears.

At what point does the 24V 19W fan hit its thermal or speed limit under continuous load?

The GreenTech EC motor is rated for 100% speed control via analog or serial interface up to 3350 r/min; the first limit under sustained use is the 19W power envelope, which the onboard electronics protect by holding the set speed without over-current.
