MR16 300mA 3W Power Connector (12V)

Pros: Very small size 10V to 32V AC/DC input , 1 to 5W 300mA output current mode LED driver.
Very efficient low heat production.
If you connecti it to a 12V MR16 socket , you can drive up to 3x3W LEDs in serial,

Cons: No isolating box it was designed for DIY retrofit kit - for me it is O.K.
Very short wires 30mm only - but you can replace it with soldering iron.

Other: I orderd 6 pc's and all worked perfect,
Very compact size , can push higer power if you supply higer input.
Fits to AC and DC input.
I will order more of this product.

Pros: Small size, cheap price,accurate soldered, good known MC34063 chip, driver really can produce 3w output power, has ss14 diodes bridge - not sensitive to the polar-ity of the input DC voltage and can work on AC too.

Cons: too short and thin wires soldered, high ripple output voltage, I replaced the 100mF capacitor for 220mF.

Other: Good product for this money, I ordered 3 pc's and will by more for my diy projects.
