Pump station controller MСK-108

The maintainance of the set level of liquids is provided by the controlling:

•  built-in pump relay – at single-phase motors with capacity up to 1 kW;
•  coil of magnetic starter (contactor) – at three-phase motor or single-phase engine with capacity of more than 1 kW.

The MСK-108 controls the electric motor (motors) of one or two pumps in automatic mode, using one of the built-in algorithms.

The MСK-108 provides the operation with liquids of different electrical conductivity – tap or contaminated water, milk and food (weakly acid, alkaline, etc.).
