2 Easy Automatic Inverter/Mains AC Changeover Circuits
I have been put forth with this question many times in this blog, how do we add a changeover selector switch for automatically toggling of an inverter when AC mains is present and vice versa. And also the system must enable automatic switching of the battery charger such that when AC mains is present the […]
Mains AC Home Protector Circuit
This simple mains 220 V, 110 V AC voltage home protector circuit will protect all the mains operated appliances of your home from high and low voltage situations and also from sudden voltage surge. The circuit can be used with 220 V AC inputs and also with 110 V AC inputs. The circuit will basically […]
2-Stage Mains AC Voltage Stabilizer Circuit
In this article I have explained how to make a 2 relay or two stage mains AC voltage stabilizer circuit for controlling and regulating 220V or 120V mains voltages through a simple circuit. Introduction In this power stabilizer circuit, one relay is wired to select the high or the low tap from the stabilizer transformer […]
Mains AC Overload protection Circuit for Voltage Stabilizers
In this article I have explained how to make a cheap yet effective mains operated AC overload and over-current protector circuit using very ordinary discrete components. Introduction I have published a few mains voltage stabilizer circuits in this blog, these units are designed and intended for safeguarding the connected appliances at their outputs. However these […]
AC 220V Over Current Monitor and Cut OFF Circuit
The proposed AC mains 220 V load over current cut off circuit continuously monitors the current flowing through a connected load. If this current increases beyond a certain preset level, the circuit trips the relay and disconnects the load from the AC. Basic Working This 220 V over current cut off circuit is indeed subject […]
