ebm-papst 4114N/12HR — Industrial DC Fan for Inverter Cooling

The 4114N-12HR is a 24V DC axial cooling fan from ebm-papst — one of the world's leading manufacturers of industrial fans and motors, with headquarters in Germany and a reputation for precision-engineered cooling products. The 4114N/12HR is from ebm-papst's 4114N series — the 120mm DC fan family for industrial 24V powered equipment.

The 126.3 CFM airflow at 4000 RPM makes the 4114N-12HR a high-performance 120mm fan — delivering significantly more airflow than typical 120mm fans at similar voltage. This performance is consistent with its primary application as a cooling fan for industrial inverters, where high IGBT power dissipation requires maximum airflow within the standard 120mm panel mounting format.

Key Specifications

ebm-papst Engineering — Premium Industrial Fan Standards

ebm-papst is internationally recognised for fan engineering excellence — their industrial fans are specified in demanding applications where reliability and performance consistency matter:

EC (electronically commutated) motor technology: ebm-papst pioneered EC fan technology — DC brushless motors with efficient electronic commutation. The 4114N-12HR uses DC brushless motor design for long life and high efficiency compared to shaded-pole AC motors in the same application.

High airflow efficiency: The 4114N/12HR delivers 126.3 CFM from 8.3W — an airflow-to-power ratio that reflects ebm-papst's aerodynamic blade design and efficient motor. Standard industrial DC fans of similar size typically deliver 80–100 CFM; the 4114N/12HR's 126 CFM output identifies it as a high-performance unit.

Applications

Industrial variable frequency drives: Replacement or direct cooling fan for VFD/inverter enclosures using 24V powered cooling with fan speed monitoring — a common specification in Siemens MICROMASTER, ABB ACS, Danfoss, and similar drive platforms using 24V DC cooling fans.

Servo amplifier cooling: 24V-powered cooling fan for servo drive cabinets — the 126 CFM airflow removes heat from IGBT power stages in mid-range servo amplifier enclosures.

Industrial automation equipment: Cooling for automation controllers, power supplies, and industrial computers requiring 120mm 24V DC fans with speed monitoring.

FAQ

Q1: What does the HR suffix identify in ebm-papst 4114N-12HR?

In ebm-papst's naming system, the HR suffix identifies a specific version with built-in rotor lock protection and speed output (tachometer feedback). Standard versions without HR are 2-wire (power only); HR versions have 3 wires including the speed monitoring output. The HR designation is required for drive and inverter applications that need fan failure detection via the speed signal input.

Q2: What is the 4114N-12HR fan speed signal output format?

The speed signal output from the third wire is typically an open-collector pulse output — generating two pulses per revolution in many ebm-papst configurations. The inverter or controller monitors pulse frequency to calculate actual fan RPM. The exact output specification (pulses per revolution, signal voltage, current capability) is confirmed from the ebm-papst 4114N/12HR datasheet.

Q3: Is 4114N-12HR compatible with 12V supply for reduced-speed operation?

The 4114N-12HR is rated for 24V DC. Operating at 12V reduces the motor speed to approximately half the rated RPM (due to the proportional relationship between DC voltage and brushless motor speed in open-loop operation) — airflow drops significantly and the fan may not generate enough torque to start reliably at cold temperatures. ebm-papst's specification must be consulted for the minimum operating voltage before using the fan outside its 24V rated supply.

Q4: How do I confirm 4114N-12HR is the correct replacement for my inverter cooling fan?

Compare the failed fan's label specifications to the 4114N-12HR: voltage (24V DC), dimensions (120×120×38mm), and connector/wire count (3-wire). If the original fan is a different brand but shares these parameters, the 4114N-12HR may serve as a functional replacement. For drives with fan fault monitoring, confirm the third-wire speed signal polarity and pulse count matches the drive's fan fault input specification.
