WHAT IS IT

A step down converter.
It will convert a higher DC voltage into a stable lower DC voltage
The output voltage will be stable even if the input varies.
The output current can be made stable and the voltage varies if required

WHAT IS IT USED FOR
Taking a high voltage power supply and converting it into a lower voltage
Supplying a constant current (CC) to some device that needs it (some batteries need CC to recharge)
Keeping an output voltage stable when the input can vary
HOW DO I USE IT
Easier with an Volt/Amp meter on the output.  See my other listings
Connect your input to the IN + and –
Put a multimeter in voltage mode across OUT + and –
Turn the CC control many times clockwise till it clicks.  This disables Constant Current.
Turn the CV control to get the voltage you require.  Clockwise higher.
If the output voltage is the same as the input voltage, turn CV anti-clockwise until it starts to fall.
If you need CC, wind it fully anti-clockwise till it clicks, then put a multimeter in Amps mode across the output.
Wind the CC up until you reach the current you require.

OBSERVATIONS
Really useful power switch not normally found on these small modules
Nice beefy power terminals
Output 15V 10.0A draws 6.8A In at 24V
Temperature after 10 minutes 62degC
Controlled by a TI LM25116
A nice beefy complement ready for when you need that extra power.
Can supply more than my 185W power load can handle.  Can’t vouch for manufacturer’s 300W.
It has short circuit protection but not for long.
DELIVERY
Dispatched Same weekday if ordered before 3pm.  I hold all my stock in Surrey.
 Free 2nd Class Royal Mail tracked.  You can level up to 1st Class.
SUPPORT
My support is second to none.  Check my feedback.  I will gladly help you before or after purchase.  I love power supplies!
I’ll gladly refund you if it’s faulty or you can return it working if it doesn’t perform as you expect.
Be careful with clone UK suppliers – they’re quite often drop-shippers who have no idea what they’re selling – just check their feedback.
