The 3021 “BuckPuck” LED Power Modules are a line of true current regulated drivers for LEDs.
Unlike standard power supplies, which deliver a fixed voltage to the output, the 3021 is designed to vary the output voltage as required to deliver a constant current to the LED(s), reliably and with stability . The line of 3021 drivers exhibit high efficiency and require no external current limiting resistors or additional heat sinking. A fast response current-sensing circuit makes the 3021 ideal for applications where flashing or strobe operation of the LED(s) is required.
Ideal for driving high power leds such as Cree XR XLamp, Osram Dragon, Lamina Ceramic, Z Power and Luxeon
A wide range of options are available including AC or DC input, external dc analog voltage intensity control, TTL/CMOS logic level on/off control, and set-and-forget internal current limiting. The standard units are fully potted in an extremely small form factor and are provided with a simple 7 pin SIP connection for through-hole PCB mounting or use with the optional wiring harness.
The 3021’s built-in regulated 5V reference can provide output to power logical circuitry or microprocessor, eliminating the need for an additional power supply on the circuit board.
