Soft starter

Trade Leads Details

I. Product Name: Motor Starter

II. Mode: WGQ8-3000

III. Applications:
Our WGQ8 series soft starter are suitable for cage motors of 3-phase AC 50 ~ 60 Hz, rated working voltage is 380V, rated working power is 5.5kw ~ 550kw. for water pumps, crushers, ball mills, fans, compressors etc.

IV. Features:
1. With strong anti-interference ability, adopt high performance microprocessor digital control, reliable enough.
2. Human-machine interface: consisted by 128*64 dot matrix character LCD, 3 signal indicators, 6 simple keyboard, show the data directly, easy to operate
3. Six kinds of starting, suitable for many machines
a. Voltage slope start--suitable for high inertia machines
b. Current- limit start-- suitable for machines the current is less than 70% Ie
c. Kick start -- suitable for high static friction force
d. Slope steady start -- suitable for high inertia and low static friction force machines
e. Steady start -- suitable for light load machines
f. Point start-- to check the running direction of motor
4. Two kinds of stop
a. Free stop
b. Soft stop: The higher the setting voltage, the shorter the setting stop time, and the shorter the actual stop time.
5. Many kinds of protection, make the motor more reliable and safer.
a. High voltage
b. Low voltage
c. Input missing phase
d. Output missing phase
e. Imbalance current
f. Start over current
g. Running over current
h. Running inverse time overload (inverse time 1, 2, 3, 4)
i. Over heat
j. External fault
k. Starting over time
l. Communication fault
m. Parameter fault
6. Communication: With DCS remote control interface and RA485 communication interface
7. Analong output: 4~30mA standard analog current output
8. Installation: Compact structure, small size, easy to install and maintain.

V. Advantages
1. Reduce the start current of motor, reduce the peak current of power supply, reduce the cost of the machines
2. Reduce the capacity, avoid investment caused by capacity increase
3. Reduce machine stress, prolong the life span of motor
4. Start parameter can be adjusted according to load

VI. Type selection
a. Normal load machines, such as compressors, pump, conveying machinery, lift etc, can be chose according to motor rated power
b. Heavy load machines, such as centrifugal fan, crusher, mixer, grinder etc, can be chose according to 120% of the rated power.
