350-mA constant-current driver provides high reliability for indoor lighting

May 18, 2011 | Paul Buckley | 222907388
350-mA constant-current driver provides high reliability for indoor lighting Phihong has developed a new series of 12 W drivers for indoor LED lighting. Designated the PDA012A (for AC input of 220-277 VAC) and PDA012B (for AC input of 100-120 VAC), the 350 mA constant-current driver operates at an output voltage range of 10~43 VDC and is ideal for applications such as display lighting and strings of a few high-intensity bulbs.

The PDA012X series has an ingress protection of IP20, meaning that it is rated for indoor dry environments only, and its small, lightweight design enables it to be easily integrated into a variety of interior and architectural design projects.

The 12 W driver is available in two models at each power level:  a base model which has a lifespan measuring approximately 50,000 hours, and a higher reliability -H model which extends life to approximately 100,000 hours. The series features a wide operating temperature range with full functionality at -40 to 50°C for full power and may be extended to 60°C with power no greater than 10 W.

Standard features on the lighting power supply include over-voltage, over-current, short-circuit and open-circuit protections including brownout, brownout recovery. Additionally, the driver meets UL8750 and UL1310 and bears safety approval marks for UL and CE.

The PDA012X series measures 132 mm x 30 mm x 22 mm and weighs 150 grams.
