Hello, I am designing a project which will require 20Vdc (max 20A). I want to make a continuous over voltage protection that could withstand max of 250V. For example, if someone accidentally plugs 250V in instead of 20V, some clever circuit (or IC) should disconnect the system.
I have a small motor vibrating motor for a table . its a 12volt DC 100ma. does that mean i should look for a plug that is 12dc with .1amp. If so can i get a plug that can be 12 volts DC 5 amp i
The Circuit Breaker Size for a 230 Volt Air Conditioner. Kevin, according to the specs for the air conditioner the circuit that should be installed would be a 30 amp 230 volt circuit using 10/2 cable with ground. The circuit breaker for this air conditioner circuit should be a 2-pole 30 amp breaker. More about Electric Circuit Wiring for a 230
Nearly all computer power supply units (PSUs) are switched mode power supplies (SMPS). The mode of operation is: Rectify the mains voltage. Charge a high voltage capacitor to mains peak voltage. Feed the DC through a ferrite transformer and high-voltage switching transistor. Switch the transistor at high frequency.

World Voltages. The world runs in two voltage ranges: 110-127V or 220-240V. If your device falls within either range, variations within that range won’t be a problem for short-term use. If the local power is 110V, for example, and your device lists its input at 125V, it will work.
