Automatic PDM 1
The simplest automation, suitable for pressure vessels, level monitoring, solar panels.
This is the simplest automatic with the lowest consumption. It cannot automatically switch the network in the event of a power failure. It is intended for operations that need to start the power generator based on an external request. The most common are, for example, a decrease in the value of the batteries and the requirement to recharge them, a drop in the pressure in the pressure vessel, an increase in the water level above the controlled limit.
