  • Good quality, 7.4W output, 8.6 watt consumption

    posted by nagymate

    Small, good quality. High frequency output (LEDs will not flicker). Protected against too small resistance loading.Large input voltage range.
    While output power is around 7.4 Watts, consumption is 8.6 Watts (from 230V input voltage). This means 86% efficiency. Output voltage is vary depending on the loading to achieve almost constant current. In case of open circuit the output voltage is around 45 Volts.
    If You only need only 7.4 Watts and 86% efficiency, this product can be a good choice for You. You cannot use 10W 12V LED chips with this, because the lowest output voltage is higher than 12V
  • Great for DIY lights

    Its sealed so no need to worry about electrocuting yourself on components at mains voltages. Mounting lugs to attach it to your housing.
    I used two of these to under drive twenty 3 watt LEDs in a florescent light housing.It would be nice to have 20w drivers that can drive four 5 watt LEDs or two 10 watt LEDs, so I had less soldering to do.
    Great easy to use driver for twenty 1 watt LEDs (10S2P) or to under drive ten 3 watt LEDs.
  • Neat little product, but they could've put in a bit more amp for the price

    This is an extremely nice LED driver as it is beautifully finished and works just fine. Voltage output is a nice steady 12.5 volts (very accurate since the stated output voltage is 12 volts) and stays cool under load. Polarity is conveniently stated (both) on the LED driver body (sticker) and using colour coded wires. The driver body frame also incorporates two convenient mounting holes for easy installation.
    Using this to drive my SKU 164358 10W LED and my SKU 8944 cooler together in parallel (which both run fine together, if anyone's thinking). And although I am planning to operate this on dry conditions this thing is waterproof as stated by them, so feel free to install this/these in damp conditions (haven't tested for this feature myself though).
    I would definitely recommend it to anyone looking for a compact, enclosed LED driver of this power range, but I guess people could go lower regarding price if they opt for (or find) an "open" design which I'm very well sure won't be the least water resistant - this is waterproof on the other hand (haven't tested for this feature myself though as I've stated before).
  • small dc-dc converter

    posted by nuralist

    The device was bought for powering Cree xml diode to limit current. The device have Voltage and Current regulation. My diode takes 3 ampers of current so I had to use little radiator with a thermal grease on the LM microchip, without it temperature was more than 100 C and LM chip protection had tripped. After i've used heat sink everythink became OK)
    informative specification
    good deal
  • Good quality LED driver

    posted by smv1210

    Good schematic, high quality components are used.Protection against the load short circuit or breakage does work quite OK.
    Output voltage (DC 30~36V) information can confuse some potential purchasers/users. In fact, output voltage range is much more wider: 20~36V at least. The usage of TSM101AI in the driver's output voltage/current control schematic, means, that some experienced users can even implement (an analog) dimming there ;)
    Good product for its money!
