Product Description Inspection of product
nameplate: Confirm whether the cargo received by you is consistent
with the product ordered by you. Service conditions Service
conditions have a great influence on normal working and lifetime of
the soft starter, thus the soft starter should be installed in the
place with the following conditions met.Service conditions of
conventional product: Power supply: Electric supply, self-provided
power plant and diesel generating set. Three-phase AC: 380V (-20%,
+15%), 50Hz. Applicable motor: General squirrel cage asynchronous
motor (the wound-rotor motor can be negotiated). Start frequency:
The standard product is suggested to be started/stopped not more
than 15 times an hour (based on load). Cooling mode: The standard
type is natural air cooling. Protective grade: IP00. Environmental
conditions: The environment temperature is -25ºC~40ºC, and the
humidity is ≤95% (20ºC±5ºC). There are indoor installation and good
ventilation instead of condensation, flammable, explosive and
corrosive gases and conductive dust. The vibration is less than
0.5G and the capacity should be lowered accordingly for use when
the elevation exceeds 2,000 m. Pursuant to actual rate
current of the motor, rated output of soft starter should be reset
at the time of use with reduced capacity to ensure accuracy of
various control parameters and fault protection.Operating principle

Photos Function:Lower starting current of the motor,
reduce the power distribution capacity and avoid capacity-increase
investment; Reduce the starting stress and prolong the
service life of the motor and related parts; Various starting
modes, setting of wide range of current, voltage and time and
adapting to start/stop of the motor based on a variety of loads.Our
soft starter is cored on advanced dual-CPU control technology.
It controls controllable thyristor module, realizes soft starting &
stopping of three-phase AC induction motor, and has wide range of
protection functions e.g. overload, input phase failure, output
phase failure, load short-circuit, starting limiting overtime,
over-voltage, and undervoltage. Our ProductsOur AdvantagesThe
CGR series digital AC motor soft starter is a new type of starting
device designed with power electronics technology, microprocessor
technology, and modern control theory, which has reached the
international advanced level. This product can effectively limit
the starting current of asynchronous motors and can be widely used
in loads such as fans, water pumps, conveyors, and compressors. It
is an ideal replacement for traditional reduced voltage starting
devices such as star/delta conversion, autotransformer voltage
reduction, and magnetic control voltage reduction.Our CGR
series soft starter has significant advantages in comparison
to similar products.Starting mode based on a variety of loads is
used There are rich and diverse ways to start and convenient
parameter settings, enabling the motor to achieve the best start
effect based on different loads. High technical performance Because
the high-performance microprocessor and powerful software support
functions are used, the control circuit is fully simplified and
optimized and consistent and accurate operating performance can be
realized without adjustment of circuit parameters. High reliability
All electrical elements are strictly screened and the control part
of the whole machine is subject to high temperature cyclic test and
vibration test which ensures high reliability of outgoing product.
Optimized structure Unique module structure and mode of connection
entering at top and leaving at bottom are adopted, the anti-jamming
technique is introduced, rational layout of control panel is
conducted and the keyboard is of I2C bus with small volume. The
optimized structur
