WHAT IS IT
A cheap boost converter that converts an input voltage to a steady, higher output voltage.
NOT for mains use – DC-DC only.
WHAT IS IT USED FOR
Powering an item that needs a higher voltage than the voltage you have available.
You could charge a 19V laptop from a car battery with the right cables
HOW DO I USE IT
RV1 CV-ADJ CCW = Increase voltage
RV2 CC-ADJ CW = Increase current
To setup voltage, turn RV2 CC-ADJ to max by turning clockwise till the pot clicks. Then, without a load, adjust RV1 CV-ADJ to the voltage you need.
If you need to control current, put an ammeter in the output (see my combined Voltage Ammeters!), turn the RV2 CC-ADJ to min by turning anti-clockwise till pot clicks, apply load, and increase RV2 CC-ADJ
Min 8V Max50V
Do not go below the min voltage, as the output voltage goes very high
Max 15A, but 8A continuous. Provide air cooling if the heatsinks get hot.
A large input current will generate lots of heat.
Min 11.5V Max 67V
Max 12A, but 7A continuous. Consider air cooling if heatsinks get hot.
Reverse protection on input
Very basic short circuit protection for a short period- don’t short to set current.

This is a cheap power supply. Don’t run it at its maximum – give it some headroom.
12V 9.5A 114W => 24V 4.35A 104W = 91%
24V 4.38A 105W => 36V 2.8A 100W = 96%
24V 6.58A 158W => 36V 4.2A 150W = 95% 50 degC after 10 minutes
36V 5.08A 183W => 48V 3.72A 178W = 97% 57 decC after 10 mins
