this shit.... smh giving me some MF trouble i say200w to 400w grow light in the works. max power would be 400w unless i add my last replacement cob. probably wont.
so this is just the ballast circuitry. tl494cn PWM integrated circuit driven buck converter. the torroid im using is a hand wound tuning torroid so i can adjust it as i find the value needed.
I'll add a RF choke on the DC positive side so i dont fuck with the city power and get a call.
i do capacitive ballasting already for simplicity. ill post a schematic of these easy ballasts for those interested. i didnt label the LED voltage and current ratings. theyre 100w 30-36vdc and max @ 3-3.5A
since theyre in series theyd max around 120v so i run them @ 90-100vdc and just protect them with a fuse in case of lightening. to increase available current in a capacitively ballasted LED panel, i want to just add another fairly large capacitor. the Xc or capacitive reactance is 1÷(2piFC) and is rated in Ohms. F is 60Hz in this instance. and C is a 104uF right now but will bump up to 400uF later in flower for a higher light intensity.
im sure iv shared this before but here it is again as i think of it.
ill post the tl494cn buck converter as it happens. i need to pull a bridge rectifier off the fans and replace with a 12v 2a dc wall plug. i needs it!
