fan is DC DC motor and speed control function, directly applied to the
AC power input environment, the use of high efficiency and energy saving
DC DC motor, power consumption compared to the general AC motor to
reduce more than 80%, and our company according to customers IP56, IP68 and ATEX explosion protection protection design to protect the long-term use of products and security.
cooling fan, it is estimated that we are familiar with it can be
divided into AC fans, DC fans, EC fans which AC cooling fan is what we
call the cooling fan, the principle of this fan and production methods
are very simple, so we focus on Take the DC fan and EC fan.
DC fans and EC fans are DC cooling fan, but there is a certain
difference between them, a simple summary: DC input is DC, EC can enter
the AC, and AC into DC.
fan features: EC fan fan industry is a new species, it is different
from other DC cooling fan, it can not only use the DC voltage power
supply, but also can directly use AC voltage power supply. Voltage from DC 12v, 24 v, 48v, to AC 110V, 220V, 380V can be universal, do not need to add any inverter conversion. All internal components for the power supply DC power supply, built-in
DC variable AC, the use of rotor position feedback, three-phase AC,
permanent magnet, synchronous motor.
fan of the advantages: EC motor for the built-in intelligent control
module DC brushless maintenance-free motor, comes with RS485 output
interface, 0-10V sensor output interface, 4-20mA speed switch output
interface, alarm device output interface and the main From
the signal output interface, the product has a high intelligence, high
energy efficiency, high efficiency, long life, low vibration, low noise
and continuous uninterrupted work and so on.
