Current Limited Centrifugal Fan 310 Backward Curved 115V 2350
PSC has been in the Thermal Solutions business since 1993.PSC
defines Thermal Solutions as all the components necessary to
accomplish the cooling of an Integrated Circuit to a PCB to a
Chassis to an entire Rack.
The company’s headquarters have been in Oxnard, California for more
than 20 years. PSC in the USA functions as a Sales and Marketing
entity with Warehousing and Engineering design and support
PSC has ownership factory located in Shipai, Dongguan China. This
factory is dedicated to manufacturing EC and DC fan designed by
PSC’s China engineering team.
The PSC China Sales and Management team has excellent English
speaking so communication is never an issue.
The company’s core engineering competence in China is focused on
the development of comprehensive DC and ECAC Backward Curved
Impeller product line and the continuous engineering of more
advanced devices in this product category
EC centrifugal fans with backward-curved blades are used primarily
for intake suction. Since most of the pressure build-up takes place
in the impeller, there is generally no need for a scroll housing.
The centrifugal fans have very good hydraulic efficiency and are
ideally suited for high pressures. The centrifugal fans are used in
applications such as central air conditioning units or building
EC centrifugal fans with forward curved blades always require a
spiral housing. Their characteristic features are a low noise
level, relatively small air flow with a high increase in static
pressure, and space-saving application. Depending on aerodynamic
and geometric requirements, the impellers are arranged in
single-inlet or dual-inlet configurations.
EC stands for Electronically Commutated, and it combines AC and DC
voltages bringing the best of both worlds.
The motor runs on a DC voltage, but with a single phase 230VAC or
three phase 400VAC supply. The motor incorporates voltage
transformation within the motor.
The non-rotating part of the motor (stator) is extended to make
room for an electronic PCBoard which includes power transformation
AC to DC, as well as the controls.
An EC motor (Electronically Commutated) is a brushless, direct
current, external rotor type of motor. In commutation electronics,
an AC voltage is changed into a direct voltage by a commutator.
The motor position is dependent upon voltage supplied via an
inverter module (similar to the principle of a frequency inverter).
The EC commutation electronics are different from a frequency
inverter in that they decide how the motor phases in the stator are
supplied with current (commutation) depending on position, rotation
direction and default.
