This circuit is absolutely NOT isolated from house line. If input voltage is 220vac, the output will be about 110vac vs ground/earth, and quite fatal. Anyway you can make it more effective. Behind the capacitors should be a full-wave 4-diode, with zener and rectifying caps at output. The circuit then can provide max current 60mA at 220v (using 2x225 cap)
@@mohanmovibrothers3539 The current going thru the cap can be estimated as of 70mA per 1uF. Simply it comes from the formula Zc (Ohm) = 1/2(pi)(Freq)(Farad), applied for V=220vac and Freq=50Hz. So you need a 15uF for your demand. Out-voltage relies on resistance of the load 5V 1A means load is about 5 Ohm, otherwise clamping it with zener circuit
There are a few thins wrong with this circuit: 1) the zener diode should be AFTER the power diode 1N4007. 2) the resistors are rated 200V max. 3) the resistors make it not an isolated power source.
The capacitors are also not rated for use on AC mains voltage; normally, such capacitors will have markings from various safety agencies to show that they are rated for that use.

This is nice circuit to use as power failure detection circuit. You may connect the output to an MCU via Opto Isolator and create your own algo that responds accordingly to power failure. I did similar circuit to this using old transformer which detect power failure with alarm sound of 2 x AA batteries when power fails. This is because someone turns OFF the main power to disable all alarm and camera systems, you can be warned once someone shuts down the main AC power from house main pannel. You may then use an IP wireless transceiver to boradcast the power failure signal to remote location and confuse the thieves and intruders with alarm sounds from unknown locations.

This is not isolated! I understand there is no galvanic connection because the capacitor includes an isolator between the conductors, but current still can flow through your body to earth if you touch the low voltage wire. This is more dangerous then the original dropper (if the neutral is the common), at least the zener clamps the volage to the neutral there.
There are a few thins wrong with this circuit: 1) the zener diode should be AFTER the power diode 1N4007. 2) the resistors are rated 200V max. 3) the resistors make it not an isolated power source.
@@erikdenhouter The zener is at the right place. Because the capacitor has to drop AC , not DC (there is no reactance at DC). In this case the current can flow through the zener both ways so you have AC. If you put the rectifier diode before the zener, the current can flow only one way, so you will charge up the capacitors with DC, then nothing happens. But, if there is no common neutral (to handle triac for example) it would be much better to use a full bridge rectifier, to double the power.
@@zoldprespan2389 You are right I think, I forgot the negative pulse to have a path. For that I would, as you also stated, rather use a bridge rectifier, it makes it also more efficient so you could use smaller caps for the same power needs. And then the zener would be placed correctly after the bridge, just parallel to the filter cap.
Hi, the circuit is ok but there's not any isolation. You only could isolate it with a transformer, so the line voltage would be linked to you magnetically
It's not fully isolated as you still have a resistor between mains and output. Albeit this resistor is of high value and is used to discharge the capacitor

The resistors in this circuit simply discharge the capacitors. It is not necessary to take 1 MOM... Any resistor from 480 kOhm and above will do. Capacitors have their own resistance to alternating current. For example: 1 UF - 3.12 kOhm, and 0.47UF - 6.77 kOhm.
