Smart cities is definitely one of the latest buzzwords, together with the Internet of things (IoT), cloud computing, smart data and visible light communication (VLC). Interesting enough, it is actually the presentation of these factors integrating all together on a scale of a city. Everything in a city–transportation, communication, security, water and power supply, and other community services–through networks, computing, analysing, and data transfer, can be more efficiently managed and improved. This is how a smart city is conceived.

MEAN WELL has released LDD-L (300~1500mA, step down mode and low voltage input), LDD-H (300~1000mA, step down mode and high voltage input) and LDB-L (300~600mA, buck-boost mode and low voltage input) series into the DC-DC LED constant current driver market for years and has been widely adopted. In order to further meet the application demands, MEAN WELL pushes the output current of LDD-H series up to 1200mA/1500mA and is pleased to unveil LDD-1200~1500H/HW models.

MEAN WELL, the leading brand of the standard power supply manufacturer, will show on the topic, “MEAN WELL, Driving your intelligent life” in this year’s Guangzhou International Lighting Exhibition. Many new products which are primarily exposed in the whole world will be brought to the show, including indoor application power supply (AP/LP series), super high-efficiency water-proof power supply (ELG/HLG series), circular shape power supply for bay lighting (HBG series), new generation enclosed power supply (LRS series), super-slim LED display power supply (HSP series), and etc. It is to be splendid!

In response to the increasing demands of DALI control for LED lighting applications, MEAN WELL introduced the DALI to PWM converter~DAP-04. Along with MEAN WELL’s LED PSU equipped with “3-in-1” dimming function, this new product makes the DALI control possible on LED lighting fixtures. DAP-04 equipped with both DALI dimming and push-dim functions.

After the launch of LDD-H/HW and LDD-L/LW series, MEAN WELL further announced two kinds of DC-DC Buck converter with constant current output for LED driving purpose ~ LDD-HS and LDD-LS series. With SMD package, they are suitable to be mounted by surface mounted-process (SMT) on the system PCB of lighting fixture and save the labor cost of installation. LDD-HS features with 9~56VDC input and 2~52VDC output range while LDD-LS possesses range of 9~32VDC input and 2~28VDC output. Both series provide multiple output curren...

Mean Well has extended the power range of its power supply family to 90W with the introduction of the LPF-90(D) series, which equipped with a range of basic functions, while the LPF-90D series boasts additional, three-in-one dimming functionality utilising a 1 to 10 V d.c. PWM signal or variable resistance to achieve brightness reduction and energy savings. The power supplies achieve IP67 protection and are enclosed in a plastic case with 94V-0 fire prevention level. Their internal shock absorption can withstand 5 G vibrations. They possess up to 91% efficiency and c...
