    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. Pros: Good efficiency, compact form, screw terminals, seems good quality Cons: No you to... Read more

    Good quality build, very easy to use after I figured ou how to wire it and set trimmers. To save your time here is the wiring: IN + - to DC power source OUT + - to your LEDs GND to controller's ground (i.e. Arduino) PWM to controller's PWM output, TTL logic, 0% duty cycle means full power, 100% -...

    - Voltage/Current potentiometers are precise - LED changes color at configurable current threshold - Can easily be abused as a battery charger for SLA or LiIon batteries - Without forced air cooling it can only handle about 4A. - When it gets hot, the voltage drops under load - Quiescent current...
