SRamakrishnan it is not stable for DC current especially for solar. measuring dc current in solar wire gives fluctuating results

SRamakrishnan you might need to adjust the trimpot by setting the voltmeter pot to 0 turn left fully and turn trimpot to set. ref voltage of 0

Ερ: Can I use 12V 3A transformer for power supply for it?????

Ερώτηση από Wrestling TV επί 2019-03-22 07:57:29

SRamakrishnan yes, 0-12v will give output of 15 to 17v

SRamakrishnan should be 1 year but you can contact banggood. some manufacturers don't provide warranty for vendor purchase

Ερ: what is 100k trimer for?

Ερώτηση από vaklev επί 2021-03-28 01:51:02

SRamakrishnan it is to balance output to 0 when voltage is set to 0. post new build, just set the voltage and current to 0 and use voltmeter and keep the trimpot rolling until the output is 0

SRamakrishnan just use 12 0 12 or 0-24 AC transformer.. 12 0 12 worked forme. output is at 24v max and pot balanced and no load amp is 0. no red light

Ερ: what are the dimensions of the circuit board?

Ερώτηση από Adilson Coeli επί 2018-01-22 07:33:38

SRamakrishnan not sure. you can measure with scale

SRamakrishnan it is because of AC transformer winding. some transformers has few more winding and the AC input voltage will be slightly more which could give higher output voltages. no need to worry. 27 is normal. if you still want 30 or more voltage, you can I create the main filter capacitor or change transfer . you can use 15 -0-15, which gives you 34 voltage

Ερ: If I used a transformer that already output is 24v DC, Will is Ok? Or will I lose something?

Ερώτηση από BruceY30 επί 2017-12-21 11:29:55

SRamakrishnan ok. 0 -24v is good. not 24 -0-24v
