Rpe Srl is promoting the PWM board, a control system for solenoids and solenoid valves, suitable for applications in environments with high temperatures and for a long time. The board, patented by Rpe, is very compact and available in two versions: 24V DC (image on the right) and 230V AC. Its strong point resides in the substantial reduction of the consumed energy, about the 60% saving is in fact possible. Besides, it notably decreases the electromagnetic pollution (Emc), it reduces the work temperatures of coils by 50% and it is a stand-alone board, i.e. it can be used on existing installations without making any HW/SW modification.
