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 VDC. With the AC input range of 90 to 304 VAC, the driver can be operated at the standard North American mains voltages of 120 or 277 VAC 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 VAC input to over 84% at 277 VAC 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.
