Hey fellaz,
I currently purchased a few CC / CV Step Up boost converters in order to charge 40 volt battery packs. I took all three of them, spaced them out evenly and powered them all in parallel. If I use one at a time they work fine.
But as soon as I try to use 2 or more at the same time, they all stop "working"... The output voltages falls and current output drops to zero... And sometimes some of them will start buzzing a tiny bit.
At first I though maybe the power supply I was using didn't have enough current output but that's not the case. The power supply is rated at 10 amps and I have each boost converter current set to 1 amp or less the same problem persist.
Any ideas?
Description:
Module properties: non-isolated step-up module (BOOST)
Input voltage: DC10V-40V
Input current: 6A (MAX) exceeds4A please enhance heat dissipation
Quiescent current: 10mA (12V liter 20V, the output voltage, the higher
the current will increase too quiet)
Output voltage: 10-50V continuously adjustable
Constant] range: 0.2-6A
Temperature: -40 to + 85 degrees (ambient temperature is too high, please enhance heat dissipation)
Operating frequency: 150KHz
Conversion efficiency: up to 96%
Overcurrent protection: There
Input reverse polarity protection: Yes,
Installation: 4 3mm screw holes
Connection method: Connection Output
Module size: Length 70mm width 36mm height 13mm
Single module: 50g
