Sunonwealth Electric Machine Industry Company Limited designs and manufactures a full range of high-performance fans, blowers and coolers which includes DC brushless fans, micro DC blowers, CPU coolers, graphic card coolers and AC fans. Sunon manufactures some of the industries smallest, thinnest and most power efficient fans and blowers in sizes ranging from 0.315 inches (8mm) to 10 inches (250mm) in outside diameter and from 0.157 inches (4mm) to 1.5 inches (38mm) in thickness. More than 700 different models are available to customers.

Amar Radio Corporation, Bangalore, is an authorized distributor of Sunon since 2000. Need to place an RFQ? Get in touch.



LED Cooling Module

Sunon has managed to break through the bottleneck of the LED lighting industry. The company offers an active cooling module with high-level cooling design and micro cooling technology, low power consumption, energy saving, and an environmentally green design. The Sunon LED lighting active cooling module features high cooling efficiency, long service life, high temperature resistance, low power consumption, high reliability, and their Super Silence Fan design. It effectively satisfies client’s LED cooling need and meets the compact, lightweight trend of lamps.

Mighty Mini Fans and Blowers

Mighty Mini fans and blowers meet the cooling needs of a variety of micro products, including PDAs, smartphones, GPS modules, PMPs, UMPCs, and portable fuel cells. They possess the advantages of exceptionally low noise and lowest power consumption. These special IP55 rated fans and blowers have been tested at an average temperature of 75°F at 67% RH for dust water testing (excluding size 8 x 8 x 3). These fans and blowers have been widely adopted in IT devices, telecommunication, consumer electronics, medical electronics, and security devices.

EC Axial Fans

Sunon’s EC axial fans use high-efficiency brushless DC motors which are driven directly by an internal AC to DC power supply. Power consumption is reduced by approximately 80% compared with Sunon’s conventional AC fans and shaded pole motors. They can be ordered with dust-proof, water-proof IP21, IP56, or IP68 ratings. For safety, Sunon’s EC axial fans also have the option to meet ATEX directive to assure the security of commercial refrigerator and freezer applications.

IP55, IP56, and IP68 Rated Fans

Ingress protection (IP) is a standard protection rating on electrical enclosures that are considered waterproof or dustproof. Sunon IP rated AC and DC axial fans and blowers offer built-in protection against dust, water, and foreign objects that can severely damage the motor of a fan or blower.  Sunon IP rated fans and blowers undergo rigorous testing against harsh environments such as water jets, rain, flood, salt fog, moisture, severe dust, and dirt exposure. The difference between IP rated fans and blowers versus non-IP rated fans and blowers is in the potting process and the type of materials used for the coating of the electrical mechanics of the fan or blower.

SA Series Board Level Heat Sinks

Sunon’s SA series aluminum AL6063-T5 heat sinks lower thermal resistance values and pressure drop. The pin fin structure heat sinks with adhesive attachment, offer an omnidirectional design engineered to maximize air intake, while the hot air dissipates from the pin array simultaneously in every possible direction.

PF Series with Tachometer and PWM

With the rise in thermal control demands, Sunon has released a selection of their most powerful and efficient PF series DC fans with standard 4-wire pulse-width modulation (PWM) input and tachometer output functions. The PWM function regulates the voltage-signal between duty-cycles to control the speed of the fan, while the Tachometer wire provides feedback on the fan’s RPM.
