BuckPuck 350mA AC LED Driver (PCB Mount)

Unlike other drivers the 3021-A-E-350 is designed to deliver a fixed current output of 350mA regardless of the number of LEDs connected and is ideally suited for driving arrays of Luxeon LEDs.

• One driver can power one or more Luxeon 350mA LEDs with no additional circuitry or components
• AC or DC input voltage (7-24VAC or 5-32VDC)
• 350mA true constant current output regardless of the number of LEDs connected to the driver
• Provides full range dimming with a single external 5k linear potentiometer
• On/Off control pin allows you to switch off the output current without turning off the input power
• External analog/digital intensity control (TTL compatible)
• Output short circuit protection up to 15 seconds
• Output open circuit protection
• External pulse and strobe control input
• Built in regulated 5V reference/output to power local logic circuitry/µProcessor
• Extremely small form factor, just 0.78”x 0.78”x 0.43” and weighs just 0.3oz. (20mm x 20mm x 11mm, 9 grams)
• Thermally-conductive, electrically-insulated, encapsulated puck
• Simple 7-pin SIP connection suitable for through-hole PCB mounted or optional HEP wire harness
• Supplied with 0.030" square pins for easy PC board mounting
• Requires no additional heat sinking
• 95% efficient

Easy to use wiring harnesses that do not require this driver to be mounted to a printed circuit board are available with and without a dimming potentiometer. See the Accessories, Related & Optional Items table below for details.

This driver is suitable for all 350mA rated LEDs including all Luxeon I, Star/O, Star/C, Floods, Lines, Rings, and the Luxeon PWT.
