A new series of 150W constant current LED drivers for commercial lighting applications has been introduced by Phihong. Well suited for use in both dry and damp locations, and featuring optional 0–10V dimming, in addition to a 20V auxiliary output for controllers, the new PDA150 Series LED drivers provide energy efficient, flicker- and shimmer-free performance in a range of commercial LED lighting applications, including indoor and outdoor fixtures, area, high bay and architectural lighting.

Rated for input voltages spanning 120-277V AC, PDA150 Series LED drivers deliver 150W output power and typical efficiencies of 94% at 230-270V AC and 92% at 120V AC. Available with six constant current outputs (350mA, 530mA, 700mA, 1050mA, 1500mA and 1680mA), the series has a life expectancy of 50,000 hours at full output power, 50°C ambient temperature, and ≤80°C Tcase, and 100,000 hours at ≤65°C Tcase, and is covered by a five year warranty. Water- and dustproof per IP66, PDA150 Series LED drivers can tolerate humidity levels ranging from 10-95%, and feature over-voltage, over-current and short circuit protection that allows them to withstand sustained open circuit and short circuit output conditions without damage.

“The new PDA150 Series LED drivers deliver outstanding, high efficiency performance over long operational lifetimes and have several additional features designed to provide effective, value added solutions in residential LED lighting applications, including optional 0-10V dimming and a 20V auxiliary output for controllers,” said Keith Hopwood, Vice President of Phihong.

PDA150 Series LED drivers are rated for use in operating temperatures spanning -40°C to 85°C, and exhibit power factor correction of ≥ 0.9, total harmonic distortion (THD) of less than 12%, and a 0.5mA maximum leakage current at 277V AC. The series is also certified to CE, UL8750 and RoHS safety specifications.

PDA150 Series LED drivers measure 241mm x 59mm x 39mm (9.49” x 2.32” x 1.54”), weigh 1,043g (2.3lbs), and utilise standard length (25cm/10”) 18AWG solid copper lead wires for the input, output, 0–10V dimming and auxiliary.
