  • Good regulator for power LEDs

    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.
    Pros:
    Good efficiency, compact form, screw terminals, seems good quality
    Cons:
    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.
