Hi all,
I'm a newbie and not really and EE person but need some assistance
I am trying to build a power supply that will deliver about 348V using 2 LED drivers connected in series. I also have a digital voltmeter connected to the circuit which displays the voltage and current that the unit delivers.
Since my digital voltmeter maxes out at 300V, i don't want the power supply voltage to exceed 300V rather i want it to output around the 295Volts sweet spot.
I know that i can use a limiting resistor to limit the output voltage but need some help to calculate the exact resistor to use to achieve this.
Any assistance will be appreciated.
