High power LEDs are used in an ever-widening range of applications because of their advantages over conventional lighting sources. Among those LED advantages are higher efficiency, longer lifetime, and improved reliability. However, these high-output LEDs produce more heat than traditional LEDs.

STAR LEDs lifetime is reduced when it operates above its operating temperature range. Irreparable damage occurs when the junction temperature exceeds a certain point. It is imperative to control and maintain a maximum forward current to minimize extra current being dissipated as heat.

The 1 watt driver has been designed to limit the maximum current delivered to the LED circuit through a constant-current step down driver setup which will control and maintain your high power LED(s).

The driver will limit the current to 285mA (+/- 10%), with a Ripple Current of 4mA RMS, 26mA p-p. Absolute maximum input voltage is 24v DC with a recommended input of 7-16v DC.

The driver is capable of running from one to three high power LEDs connected in series.
