Simple Start Circuit With Full Mains Voltage
The launch of the A.T.K.v.d. with the full voltage of the network on its windings, i.e. directly, it is usually carried out without the approval of the PPC, and it concerns low-power motors with a peak current (e.g. less than 30 A for an overhead network and frequent starts of more than one per hour) .
Phase and neutral (voltage) monitor - Why, how and where is it used?
A very important component that serves to protect our devices in an installation, is the voltage monitor.
