The above are product highlights and not the complete manufacturers datasheet. Figure 15 shows an inverted input configuration using a 2N or other PNP switching transistor. LED Optics Optics control the illumination pattern, either diffusing it or focusing it as your application requires. Come a long way since the early days of led lighting. These drivers are very reliable and you can use the dimming inputs for different output modes.

Yes, the BuckPuck is designed to work with V dimmers like ours here.

Also, as is the case with a dc control signal, the logic input ground should to be common to the LED output terminal. When using this configuration, bbuckpuck is important that Vin be 7VDC or higher. As in the cases above, the analog control signal should have its ground common to LED.

Where DC input units are located more than 18″ from the source, a mF, 50V capacitor should be placed across the input terminals as shown in Figure For specific images and part numbers please select the options and the part number and image bickpuck automatically change; more details are included in the specifications and documentation below, but feel free to contact us should you have more questions.

In this case, a logic high will cause the output to be buckpudk.

The voltage, in millivolts X 10, will equal the output current in mA. I get about 9 hours of over lumens between battery swaps buckpcuk my 2s, which is weight of 3aa.

Temporarily place a 0. It is best practice to use an input voltage that is closer to your needs. When using an external power source for the potentiometer, the source ground must be common to the LED output pin.

Love it I use in my flashlight builds. No, the BuckPuck may run a little warm, but it does not need any heat sinking or cooling system on its own. I also should mention that ledsupply has been very helpful both with answering all my questions and with their customer service. In either configuration, connect the potentiometer such that clockwise rotation increases the resistance. Any order that does not qualify for free shipping, will by default include a discount of equal value to the free shipping offer.

A fast response current-sensing circuit permits the unit to be used in applications where ashing or pulsing of the LEDs is required. Safe, Secure, Reliable Shopping.


The output current will be zero when the switch is closed. Where the buckpucm to adjust the output current to an intermediate value is required, all output current ratings are available with an on-board potentiometer.

Reliable Driver i have bought hundreds of these buckpucks because they are small, easy to use and affordable.

The above are product highlights and not the complete manufacturers datasheet. Note that the input needs to source a minimum of 4. In either configuration, the rise time of the output will be 10? If it is running extremely hot, than something is likely wrong with the circuit. A pulse frequency up to 10kHz may be used.

This version makes it super easy to control the light for your small lighting system! Heat Sinks and housings give your project a clean enclosure while maintaining a low temperature.

A standard 24VDC power supply is a good choice for this application. The premium, silver based electrical isolating adhesive, 1: Optics control the illumination pattern, either diffusing it or focusing it as your application requires.

The wire leads make connections easy.
