Introduction
Delta is a leading global electronics company offering a broad spectrum of electronic
components and equipment including switching power supplies, color monitors, EMI/RFI
filters, magnetics, networking components, chip and power inductors, motors, resistor
networks, and DC fans. Our strong capabilities in product design, manufacturing,
automation and quality assurance make us the preferred supplier to OEM customers anddistributors around the world.

For brushless DC fans, Delta's highly experienced design engineers have in-depth
knowledge of customer applications and cooling requirements. Advanced engineering
equipment such as computerized CNC machines, anechoic chambers and wind tunnels
are used to develop high performance, low noise, and cost effective DC fans.

Delta is an ISO-9001 & TS16949 certified manufacturer for brushless DC fans, with
ROHS compliance beginning in Q2 2005. We implement strict reliability tests in thedesign stage and have put into place Statistical Process Controls at each step of the
production process. Because of our outstanding performance in quality and reliability,
Delta has earned vendor awards from major customers such as Asus, Cisco, Dell, HP,
IBM, NCR, NEC, Nortel, Philips, Xerox and others.

DC Fan With Minimum Noise
Introductions
Every model undergoes rigorous aerodynamic analysis and anechoic chamber test to achieve minimum
noise under high airflow and air pressure conditions.
High precision maintenance-free ball bearing system provides superb reliability.
Frame and fan blade meet UL 94V-0 flammability rating.
Every model features locked rotor protection and polarity protection, and offers optional frequency generator
or rotation detector function.
All DC fans are 100% balanced to guarantee low vibration and excellent durability.
Automatic multi-axes winding, surface-mount machine and highly automated assembly lines enable mass
production and consistent quality.
UL, CSA, VDE approved.

When power supply output voltage level decreases, it will result in thelowering of fan rotation speed. The irregular situation will be controlled
by using F.G. O/P through P/S circuit to increase the output
voltage and result in a stable rotation speed.
