POLI LED Power Box Series - 5 in 1 dimmable Power supply , 110-277AC/24V, 288W Output: PWM, PF: 0.95, Dim: 5 IN 1, Dimmension: 316x120.5x42mm, UL Listed, 3 yr Wrrty.

The PMA-J series is a 288 W constant voltage dimmable LED driver with three output channels supplying 24 V DC at 4 A per channel. The IP65 aluminum housing suits dry, damp and wet locations, and mounting tabs allow flat, side or vertical installation in ceiling cavities, coves and sign cabinets. Input accepts 110-277 V AC at 47-63 Hz with typical efficiency of 91% at 120 VAC and 92% at 277 VAC, power factor 0.99 at 120 VAC and THD under 15% at full load. Dimming covers Triac, 0-10 V, 1-10 V, 10 V PWM and potentiometer control over a flicker-free 0.1-100% range, with PWM output at a constant 4000 Hz. Short-circuit, over-load and over-temperature protection recover automatically. Case temperature range is -40 to +60 °C. EMC emissions comply with FCC Part 15 Subpart B. Backed by a 3-year warranty.
