Hi,
I am having problem with adjusting the current in this basic china "1500w" boost converter.
I want to power cob led with it and it needs 60-72 volts at 3.420 amps MAX.
The test setup contain 300w dummy load 8 ohms (originally for amplifier testing)
So my problem is that i cannot adjust the current low enough before the voltage starts dropping with the dummy load.
For example if i adjust
Voltage max but current low i get 2.1amps at 13,5 volts
When turning amps up, amps starts rising BUT so does voltage (for example 3.4a@33,5v) when reaching 60 volts, amps are too high.
Theres no way to do 0.5a and 60v because voltage drops immediately.
I see many people on youtube powering these cob leds with these boost converters.
Will the actual cob led behave differently than my 8 ohm test dummy load?
Dont want burn the cob
