Phihong now offers LED drivers for both indoor and outdoor applications
Phihong has developed a series of lighting power supplies for LED luminaire applications in both indoor and outdoor environments. The constant-current and constant voltage drivers are worldwide-compatible with high line and low line AC input voltage ranges and provide standard dimming on all outdoor models.
The line-up includes models for indoor use in small-footprint plastic housings with ingress protection ratings that meet IP20 specifications; they are ideal for applications that include small string lighting or a few high-intensity bulbs especially for display lighting, recessed kitchen lighting and emergency exit signs. All indoor models are constant-current, available in 350mA or 700mA outputs and provide 5.6W up to 30W of power. A selection of these LED power supplies will also be available in halogen-free options and will therefore not give off toxic smoke in the event of a fire.
Outdoor models are rated IP65 in full isolated potted metal casings and have dimming as a standard feature. Currently available are 30W-50W multi-channel, constant-current drivers with 0-10V dimming and a single-output, constant-current 10W driver with triac dimming. A 75W constant-voltage model with standard 0-10V dimming will be available soon. Applications for water-resistant power drivers include outdoor signs, street lighting, architectural designs and automotive lighting.
Additionally a 90W open-frame model introduced in 2010 is available in a constant-voltage output of 24V DC for easy integration into luminaires for street/area lighting or traffic lighting.
Standard features on all LED drivers include over-voltage, over-current, short-circuit and open-circuit protections as well as brownout/brownout recovery. Wide temperature ranges allow for a diverse array of applications for end users.
Should a users' needs not be met by a standard product offering, Phihong has a long history of working with OEMs on custom design projects to ensure that they get the most cost-effective and efficient power solutions.
