PHIHONG USA has developed a multi-channel driver designated the PDA037W-350G. The driver is equipped with four outputs of 350 mA and offers 0-10 V dimming capability. It is ideal for linear fluorescent replacement fixtures. The power supply satisfies all ENERGY STAR requirements governing power supplies in solid-state lighting luminaires.

The power supply features four constant-current outputs of 350 mA at a nominal output voltage of 24.5 V_DC. With the AC input range of 90 to 304 V_AC, the driver can be operated at the standard North American mains voltages of 120 or 277 V_AC for residential, commercial, and industrial applications. The driver bears safety approval from UL, meeting UL8750, and has outputs that are Class 2 per UL1310, making it appropriate for linear fluorescent replacement installations.

With an operation rated between 0°C and 50°C, the PDA037W is water resistant, and fully potted with ingress protection ratings of 65. The driver exhibits high efficiency and reliability, with minimum efficiency ratings ranging from 82% at 120 V_AC input to over 84% at 277 V_AC input. The calculated lifetime of the PDA037W is 50K hours at full load and an ambient temperature of 50°C.

Designed to be incorporated into retrofit fixtures in office lighting and other commercial overhead installations, the series measures 242 mm x 43.5 mm x 30.5 mm and weighs 675 g.
