BTB-9 Series
Standard Inverter ( G,P,T,H ) |
The
common character of BTB-9 series standard inverter
|
 |
| ★ Abundant function
、full specification , it is suitable for occasion of general
speed regulation 、energy saving.
|
Voltage grade contains 380V、66~690V, it is fit for
occasion that e-net voltage wave range is bigger.
It adopts Hitachi 32 digit motor control the
definite purpose MCU, and realizes advanced SVPWM control
technology optimizing current wave form , to reduce
harmonic interference, low noise 、low frequency and high torsion
Keyboard displays two kinds of different running
parameter at the same time, many kinds of monitor quantity, switch
easily.
Four
programmable output interface( two programmable
relay output interface, two open collector output interface ),many
output can be chosen.
Standard running (RUN/STOP) 、two
lines running (FOR or REV/STOP) 、three lines system running can
be chosen, it following user's inclinations
Manual pressure output
provided the possible for developing of application field
There is braking unit inside
75kW machine, it reduces cost for customers.
There is RS485 interface inside

Most machine (11~200kW)
all adopt airproof structure , no dust enter machine , long
lifetime
Independent low air-resistance cooling-air
duct, cooling effect is good.
Main loop low inductance design ,
components layout optimize, it fully shows the contribution
ability of whole machine

BTB-9G
series General Inverter
It is inverter that adopts new generation SVPWM wave technology, low speed
rating torsion output, carrying ability is strong, many torsion rise and V/F curve can be set,
many acceleration, deceleration mode can be chosen, it has
personality PID function inside, many factors can be adjusted
online, it has perfect protection function and malfunction check
system, advanced technology, full function, easy to use, it can
satisfy the demand of energy saving and every kind of production
technique requirement. There are many kinds of voltage grade, full power specification,
function is arriving to the same product standard of Europe, USA and
Japan. The application through petroleum
、chemical、plastic、paper making 、food、cement、printing
and dyeing 、machine tool
、metallurgy
、warm connection 、water supply etc. industry show: society
benefit and economic benefit is obvious.

BTB-9P Series Inverter of Ventilator pump
The rating chosen for general ventilator
pump may have definite abundant quantity, while to adjust
flow or ventilation quantity according to craft demand, it often
adopts breeze door baffle or valve to adjust. This way is simple, but it waste
plenty of energy sources. Inverter is used in the speed
regulation control system of ventilator pump, it is mainly
applied on the occasion of blower 、induced-draft fan 、water supply system etc
. Energy saving is its main aim. The energy saving
theory that adopts inverter is based on the relation
between liquid load flux 、pressure 、rotate speed 、torsion 、power
.By liquid dynamics, we know: For
water pump , P is output power of water pump, H is water
pump delivery head ( lift
) , Q is water pump flow quantity , n
is water pump rotate
speed .
Adjustment
of rotate speed can save plenty of energy sources when demand
quantity decrease. Example: when the demand for flux is 80%,
through frequency variation, it can save 48.8% energy sources only
need 51.2% of rating power. If adopts conventional valve way to
adjust flux, it can also reduce energy source waste, but the
energy saving effect has big difference with frequency variation. |

BTB-9H Intermediate Frequency Series Inverter
Frequency output can be 2kHz, it is fit for the drive of
intermediate frequency motor, it is mainly used on drive high
speed grill and wood machinery. It is easy for use together
with minimum run frequency and V/F set.

BTB-9T Series Inverter for Spin and Weave
With the improvement of technique level of
spin and weave machinery, AC frequency variation and speed
regulation became one trend. AC asynchronous motor frequency
variation and speed regulation device is applied in the most new
developed spin and weave machinery products. Inverter is applied
to every working procedure of spin and weave machinery, it
includes carding machine 、silver lapper 、comber 、draw
frame 、as well as ring spinning 、 fly frame 、 sizing machine 、warping
machine and so on. in addition, knitting machine 、nonwoven
、chemical machinery 、printing
and dyeing machine all use AC inverter. This series inverter add
the pendulous frequency and program run function.
