Product installation instructions:

1.The installation, use a length of screw less than 4mm to fix the power supply.

2. Before the installed power run, check and proofread each wiring terminals on, make sure the input and output, AC and DC, positive and negative voltage.
And current values such as the right to eliminate wrong connection reverse phenomenon, to avoid damage to the power supply and user equipment.
3. Use a multimeter to measure power before hot, neutral and ground short circuit, the output is shorted; load when power is the best start.
4. Do not exceed the power supply when using the nominal value, so as not to affect the reliability of the product. To change the power supply output parameters, the power supply to the customer before using our technical surgery department consulted to ensure the use of the product and reliability.

    I'm using the Nunerical Controller as One of the components in my lithium battery charger, variable voltage and current settings make this controller ideal to match the electrical needs of charging most batteries

    Preliminary testing suggests a FANTASTIC product, I will need to rectify that by dismantling the old power supply and finding the chip or eeprom that stores that information for the laptop

    Good product at a very decent price, the voltage is very stable and clean, you can go a bit higher than that, its a nice product and you can use this to build a variable power supply

    Nice constant voltage or constant current power module, the voltage is variable over the specified range, european size/threaded screw-holes on either side of the heat-sink

    This is a good unit, it limits nicely on both voltage and current and runs its fan when it gets too hot, this is a negative side shunt for measuring current

    Make your own battery charger, constant voltage adjustable to configure it for just about any type of batteries
