MG3 Soft Starter Frequency Converter Soft Starters For Water Pumps And Fans
Product Overview
Through the research and exploration of water industry applications, Ackwell has developed the Mg3 series of pump and fan-specific soft starters for the water industry, which utilizes a unique pump stopping algorithm to completely solve the "water hammer effect" and mechanical shock. The design adopts the industry-specific module approach, which can realize customized control solutions according to customer requirements, and is easy to upgrade and maintain the equipment.
Easy to upgrade and maintain the equipment.
Operating environment
The altitude of the installation place is not more than 1000m above sea level; if it is more than 1000m above sea level, it should be used with reduced capacity;
The ambient temperature is -10～40℃, above 40℃, it should be used at a reduced capacity, and the current should be reduced by 2% for every 1℃; ● The ambient humidity is ≤95%RH, without water condensation.
Ambient humidity ≤95%RH, no water condensation.
●Indoors where there is no corrosive gas that destroys metal and insulating materials;
●No direct sunlight, no dust, flammable gas, oil mist, dripping water or salt, etc.

Selection Precautions
● Fully understand the characteristics and usage of the load;
● The soft starter size should always be larger than the current value (rated operating current) of the motor. In case of deviation from the rated value, a larger soft starter must be selected;
● Installation altitude; no more than 1000 m, above 1000 m, consider capacity reduction.
