Modifications of ShU SIGMA

ShU SIGMA is a multi-purpose product which can find hundreds of different applications. Universality – here that distinguishes it from competitors, and functions which it is supplied simplify its operation and servicing.

The SIGMATIKA company predlagayetryad basic modifications of ShU SIGMA which provide effective management of electric motors of different function.

To destination:

• control of asynchronous electric motors of pumps (network, make-up, nutritious, circulating, recirculation, borehole, sewer, povysitelny, etc.);
• control of asynchronous electric motors of pumps and adjusting valves for thermal points, boiler rooms, etc. (with the additional built-in PID-regulator);
• control of asynchronous electric motors of pumps with regulation on level from electrodes or floats (for maintenance of level of liquid in capacities, drainage, sewer, etc.);
• control of asynchronous electric motors of fans, smoke exhausters, forced-air and exhaust systems, conditioning, etc.;
• control of asynchronous electric motors of cranes, hoisting-and-transport equipment, elevators, escalators, etc.;
• control of asynchronous electric motors on a special task.

On tension of a power line:

• 220 V;
• 380 Century.

By the number of inputs of a power line:

• one input of power supply (standardly);
• several inputs of power supply (on each el. engine);
• two inputs of power supply with AVRP (AVR of food is built in a case).

On rated current of the electric motor:

• range of rated current of the electric motor 1 … 310 A (range of power 0,12 … 160 kW).

By quantity and type of control units:

for control of one electric motor:

• actuator manual;
• management of contactors;
• smooth start-up / stop;
• frequency management;

for control of several electric motors (at most 8):

• management of contactors of each electric motor;
• smooth launch / stop of each electric motor;
• frequency management of one electric motor, management of contactors of other electric motors;
• frequency management of one electric motor, smooth launch / stop of other electric motors;
• frequency management of each electric motor.
