Phihong has developed a new multi-channel driver for indoor and outdoor lighting applications. Designated the PDA037W-350G, the unit is equipped with four outputs of 350 mA and offers 0-10 V dimming capability. Suitable for linear fluorescent replacement fixtures, the power supply satisfies all ENERGY STAR requirements governing power supplies in solid-state lighting luminaires.
The power supply is equipped with four constant-current outputs of 350 mA at a nominal output voltage of 24,5 V d.c. It has an AC input range of 90 to 304 V a.c., is rated for operation between 0°C and 50°C, and is water resistant and fully potted with ingress protection ratings of IP65. The driver also exhibits high efficiency and reliability, with minimum efficiency ratings ranging from 82% at 120 V a.c. input to over 84% at 277 V a.c. The calculated lifetime of the PDA037W is 50 000 hours at full load and an ambient 50°C.
The power supply is equipped with input over-current protection and short circuit protection, as well as output over-voltage and open-circuit protection. It also features a minimum power factor correction greater than 0,9, and is covered by a standard five-year warranty.
Designed to be easily incorporated into retrofit fixtures in office lighting and other commercial overhead installations, the series measures 242 x 43,5 x 30,5 mm and weighs 675 g.
