E280

E280 series general frequency inverter

elying on its superior cost-efficiency, E280 series general inverter is widely applied in the industry of

machine tool, electricity, textile, transportation, transmission, paper, cable,

metallurgy, etc. The series

product has been developed to be model in high stability, reliability after on-site inspection of more than

700,000 inverters.

THE SCIENTIFIC CONFIGURATION

Compact yet reasonable structure reduces the volume of inverter 20%-30% of the traditional general inverter.

Independent cooling duct and closed main loop design.

Minimum driving line transmission signal( shorter the line, smaller the disturbance and the loss is.)

Independent Cooling duct

The main loop keeps relative

sealability which reduces the

possibility for the dust, solid

particles and other matters

entering the inner machine,

b u i l d i n g a c l e a n , s o u n d

environment for the inverter

and lessening the influence

and corrosion brought by the

h a z a r d o u s s u b s t a n c e . A

sea led e lec t r ic room can

minimize the failure rate.

The duct is independent form the

body of machine, and keeps sealed

to some extent, which assures that

all the gas attracted into the fan

would pass the radiator and get the

c o o l e f f e c t . I n t h i s w a y, t h e

tempera ture o f components i s

reduced to great extent, at the same

time it improves the performance of

products, reduces the failure rate,

and increases inverter's service life.

The cooling fan applied in the inverters of more than 37kw adopts independent supplier. The power supplier can drive 6 fans

with the power of 50w and the current of 2.3A at the same time。

Adopts the DC fan characterized by the large volume, high wind pressure, excellent cooling effect and stable performance.

Special design of double conformal coating ensure the safety for the circuits.

Solution~Constant pressure water supply

Provide several water supply methods as well as rotated time

control in case of rust of the pump and improve the stability of

equipment.

Have the functions of water supply on fixed time, multi-speed

voltage setting, automatic start and sleep maximize the

energy saving.

Water short and over loading protection function.

Introduction

Traditional water supply methods such as water tower, water

tank are unable to meet the demands of constant pressure water

supply due to the slow response and di ff icul t system

maintenance. Through the closed loop control for the water

supply, we can stabilize the pressure of water pipelines, improve

the response speed as well as keep the perfect warning and

protection function which makes the maintenance more

convenient and simpler.

A stable pressure within water pipelines

Ensure that several pumps can be rotated in the fixed time.

Quick response, high stability and reliability

Protection function for the short of water, over loading,over

voltage.

Ball mill

Introduction

The ball mill controlled by the industrial frequency often results

in over grind of the material, over current for the start current and

great pulse to the grid and machine due to the long period grinding

and the low efficiency, which makes it necessary for the factory to

develop the frequency change ball mill with smooth start, high

efficiency, large yield and low energy consumption.

Product Series

Power range（KW）

Single Phase

Three Phase

Large loading amounts for the material demands the big

enough torque during the starting and the low-speed running

The process of cylinder body operation requires the whole

system to be stable.

The large fluctuation during loading needs the over current,

over loading capacity.

Different production technologies require the rotate rate in

correspondency with the speed.

Be flexible to set the speed of different time.

Realize the soft start so as to reduce the pulse to the grid and

the machine, lessen the mechanical vibration and prolong the

lifetime of machine.

Perfect protection function for over voltage, over current over

load .

Realize the automatic track of the proper current to pull the

motor, optimalize the power and save the energy.

Use the E280 series inverter to drive the motor and further drag

the cylinder to rotate. Make use of the friction and centrifugal

force to bring the raw material to a certain height and then fall

down along a parabola, resulting a heavy beat and grind effect to

the material at the bottom. The powder material is discharged

from the unloading equipment.

Adopts the E280 series inverter to realize the constant pressure

water supp ly. The sys tem ad jus ts the f requency and

increases/decreases the amounts of pumps in accordance to the

difference between the pipe nets pressure and setting voltage.
