Product Overview

Key Features & Benefits

• Low Power Consumption: Rated at only 3.12W, making it an eco-friendly choice for energy-conscious designs.
• PWM Speed Control: Built-in PWM control function (4-wire type) allows for wide-range speed control via external signals.
• High Reliability: Expected life of 40,000 hours at 60°C (and 70,000 hours at 40°C), ensuring stable operation in demanding environments.
• Pulse Sensor Output: Provides real-time rotation detection (tachometer signal) for fail-safe monitoring.
• Ribbed Frame: The frame features ribs to prevent air leakage between the fan and the chassis, maximizing airflow efficiency.
• Compact & Lightweight: Weighing only 35g, it is easy to integrate into compact devices.

Technical Specifications

Performance Data

• Airflow Characteristics:
  • The fan delivers a maximum airflow of 0.42 m3/min, capable of effectively dissipating heat from small, high-heat-flux components.
  • The maximum static pressure of 318 Pa allows the fan to push air through restrictive environments, such as dense heat sinks or dust filters.
• Noise Level:
  • At rated speed, the sound pressure level is 47 dB(A). The PWM function allows users to lower the speed during idle times to significantly reduce noise.

Typical Applications

1. IT & Telecommunications: Cooling for network switches, routers, and blade servers.
2. Industrial Equipment: Control panels, inverters, and PLCs.
3. Medical Equipment: Diagnostic imaging devices and analyzers requiring stable cooling.
4. Measurement Instruments: High-precision electronic testing equipment.
5. Office Automation: High-performance printers and copiers.
