  • Good regulator for power LEDs

    Impression:Good efficiency,Compact form factor;

    Used this as a constant current source for an 3 Watt IR LED, regulating 5V/600 mA down to 1.6V/1.75A; way more efficient than resistor-based approaches of others. Runs fairly cool, indicating good efficiency.
    Good efficiency, compact form, screw terminals, seems good quality
    No documentation, you need to scan internet if you want more details; unclear function of 3rd potmeter/LED
    OtherThoughts: if using for regulating LEDS, first reduce current/voltage using a resistor of sufficient wattage, default current is rather high at 3A. Do e.g. voltage half a volt above the normal LED voltage, then reduce current; swap resistor for LED, and turn up current to required value. Turn counter-clockwise to reduce current and voltage.
