    5 pieces of voltage regulators from 5V to 24V each for the positive and -15V on the negative side. 5 additional LM317 should satisfy all needs for variable voltage regulation. [OPERATION] Just finished a little linear power-supply that branches down from +/-15V to +/-5V and the pieces work as expected. Max current should be around 1A or so and from 300mA upwards a heatsink would be a good idea. [MOUNTING] Best thing about this kit: it comes with a ton of silicone insulation pads and plastic washers

    the product is as described. As the regulators were mixed in the box I quickly tested them. All the L780X are in tolerance, an L7905 is out of order and the L790X are sometimes in high limit without load but they are correct with load between 100 to 300mA. Given the price this is still a bargain.

    Ottimi regolatori per le tensioni più comuni ( 5v,6v,8v,9v,12v,15v,24v) e anche per le tensioni negative (-5v,-6v,-8v,-9v,-12v,-15v), più 5 regolatori lm317T per tensioni variabili. Arrivati in una comoda scatola di plastica con anche gli isolanti per fissarli alle alette di raffreddamento.

    Muy buena calidad de los productos, tenia varios proyectos parados por falta de estos transistores y ahora los voy a poder terminar. La entrega en tiempo.Los recomiendo muy ampliamente.

    Boxed in a nice (usual) plastic box and with thin isolating sheet and washers.
