Power Supplies Offer Constant Current of 350 to 1,000 mATRUMPower launches its 12 Watt LIS12 series of constant current AC/DC LED power supplies, which can efficiently drive high bright LEDs in series. This series is an addition to the company’s LED power supply product line. TRUMPower’s AC/DC LED power supplies range from 5 to 120 W and the DC/DC LED power supplies range from 8 to 12 W.

It accepts a 90 to 264 VAC universal input, which is isolated from the DC output. Featuring a high efficiency of 80%, the LIS12 series includes four standard models. Model LIS12-36-350, with a forward voltage range of 18 to 36 V is suitable for driving 6 to 9 PCS of 1 W white LEDs in series, where 350 mA constant current is required. Model LIS12-24-500, having a forward voltage range of 12 to 24 V and 500 mA constant current, is recommended for driving 4 to 6 PCS of 2 W white LEDs in series. Model LIS12-18-700 is suitable for driving three to four 3W white LEDs in series at 700 mA constant current and a forward voltage range of 9 to 18 V. Model LIS12-12-1000 has a forward voltage range of 9 to 12 V and can drive two to three white LEDs in series, where 1,000 mA constant current is required. If special output currents or voltages, different footprints or other requirements are needed, TRUMPower can custom design power supplies to accommodate to special needs.
