Phihong has developed an LED driver capable of supplying 90W of power for use in indoor lighting. Designated the PSM090-240P, the power supply’s open-frame design allows for ease of integration into interior lighting designs. The device is available in a constant current of 3.75A with an output dc voltage range of 22.8~25.2 and is designed for any input line from input voltage range of 100 to 277Vac.
"The addition of LED drivers was a natural progression to our lighting ballast business," said Keith Hopwood, Vice President of Marketing for Phihong USA. "As customers are becoming more environmentally conscious and economically savvy, the switch from traditional fluorescent lighting and ballasts to LED lighting systems is much more efficient and environmentally friendly over the long run without sacrificing lumen output."
The PSM090-240P is intended for use with architectural, street light and HID replacement applications. Its design also allows for ease of integration into custom LED lighting arrays.
The 90W LED driver features power factor correction allowing for a PF of 0.95 minimum at 115Vac input and a minimum of 0.90 at 277Vac input. The efficiency for the series is rated at a minimum of 85% and may operate within a range of -10 to 40°C.
The series also has overload, over-voltage, over-temperature and short-circuit protection and is compliant with the UL8750 standard. The PSM090-240P measures 6.65 x 2.4 x 1.22 inches and weighs 13 ounces.
