SUNON DC Fan Voltage Options for Network Infrastructure
SUNON DC cooling fans are available in four standard voltage levels, each designed for specific application environments. The 5VDC option (voltage code 0) serves portable devices and USB-powered networking equipment. The 12VDC option (voltage code 1) is the most widely used voltage for communication devices, routers, and network switches. The 24VDC option (voltage code 2) is standard for industrial-grade servers and networking equipment in data centers. The 48VDC option (voltage code 4) is specifically engineered for 5G telecommunications base stations and large-scale data center cooling, where higher voltage distribution reduces power transmission losses and improves overall system efficiency.
AC Fan Voltage Ratings for Industrial Networking
SUNON AC axial fans support a comprehensive range of voltage ratings to accommodate global power standards. The 110VAC and 115VAC options comply with North American power standards, suitable for networking equipment deployed in the United States and Canada. The 220VAC, 230VAC, and 240VAC options meet European and Asian power standards, covering the majority of international deployments. The 380VAC three-phase industrial voltage option powers large-scale industrial ventilation systems and high-capacity networking infrastructure. SUNON EC (Electronically Commutated) fans combine the advantages of both AC and DC technologies, typically supporting wide voltage input ranges for flexible deployment across different regional power grids.
Current Consumption by Fan Size
Understanding current consumption is critical for power budget planning in telecom base stations and data centers. SUNON micro fans (17mm to 25mm) typically draw between 19mA and 106mA at 5VDC, making them ideal for compact networking modules and IoT gateways. Mid-size fans show increasing current draw: 40mm fans consume approximately 0.1 to 0.5 amperes, 60mm fans draw 0.15 to 0.8 amperes, 80mm fans require 0.2 to 1.5 amperes, 92mm fans use 0.3 to 2.0 amperes, and 120mm fans consume 0.5 to 3.0 amperes. These current ranges correspond to the diverse cooling requirements of networking equipment, from small cell base stations to full-rack data center cooling systems.
Power Consumption and Thermal Design
SUNON fan power consumption scales with fan size and airflow requirements. Micro fans typically consume 0.1 to 0.5 watts, suitable for low-power IoT devices and small networking modules. Mid-range fans consume 0.5 to 5 watts, appropriate for network switches, routers, and base station equipment. Large industrial fans can consume 10 to 50 watts or more, designed for high-performance server racks and data center cooling infrastructure. For 5G base station applications, the 48VDC SUNON fans with PWM speed control offer optimal power efficiency, dynamically adjusting fan speed based on thermal load to minimize energy consumption during low-traffic periods while providing maximum cooling during peak data transmission.
Voltage Selection Guide for Telecom Applications
Selecting the appropriate voltage for telecommunications and networking applications depends on the specific use case. For portable network testing equipment and USB-powered communication modules, 5VDC fans provide adequate cooling with minimal power draw. For standard networking equipment including routers, switches, and small cell base stations, 12VDC fans offer the best balance of performance and compatibility. For industrial-grade servers and data center networking racks, 24VDC fans deliver reliable cooling with industry-standard power distribution. For 5G macro base stations and large-scale data centers, 48VDC fans enable efficient power distribution over longer distances, reducing voltage drop and improving overall system reliability. Direct AC-powered fans (220VAC/380VAC) are suitable for HVAC integration and industrial ventilation in telecom equipment rooms.
Identifying Voltage from Model Numbers
SUNON’s systematic model numbering convention allows engineers to quickly identify voltage specifications without consulting datasheets. In the new coding system, the voltage digit appears before the bearing code: 0 indicates 5VDC, 1 indicates 12VDC, 2 indicates 24VDC, and 4 indicates 48VDC. For example, the model MF20080V1-1000C-A99 contains the digit 1 in the voltage position, immediately identifying it as a 12VDC fan. This coding system is particularly valuable for telecom equipment maintenance, where technicians can quickly verify replacement fan compatibility by reading the model number, ensuring that 48VDC fans are not accidentally installed in 24VDC circuits or vice versa, preventing equipment damage and ensuring continuous network operation.
