Controller PWM Steca PR 1010 10a IP31

The Controller PWM Steca PR 1010 It is a prominent product among the solar load regulators of the market. The most modern charging technologies coupled with the determination of the state of charge with Steca-Antonic, which has been again clearly improved, form the perfect unit for the care and control of the battery.

Using symbols, a large display informs the user about operating states. The state of charge is represented visually as if of level indicators are treated. Data such as voltage, current and state of charge can also be displayed on the display with digital numbers. In addition, the controller has an energy meter that the user can reset.
