Adopting the advanced power electronic technology, UPC-D can efficiently regulate the terminal voltage of lighting source to make them run under rated voltage. In the case that the brightness is not to be influenced or in the site that the brightness is not required to be very high, we can make the lamps run with the voltage 10%~20% less than the rated voltage by using UPC-D. The energy saving rate will reach 20%~40%. Furthermore, it can prolong the service life of lamps and lower the maintain cost.

Product Function：
Adopting the advanced solid-state power electronic components, UPC-D has eliminated the defect of traditional inductive simulation technology in cost, specification and usage. It can realize smooth regulation for voltage output and current output. Controlled by special software, UPC-D has the remarkable functions of energy saving, power factor improving and output power balancing.

Applications
UPC-D is widely and successfully used in supermarket, school, bank, workshop, hospital, office and car parks etc.

Suitable Conditions
The conditions UPC-D suits for is as following,
1.Circuit Construction UPC-D is suitable for pure lighting circuits centralized controlled, but not suitable for the decentralized control system, such as individual room lighting in hotel, or where there are some circuit systems for other equipment which UPC-D is not suitable for.
2. Lighting Type For UPC-D, it is an ideal application for such lighting system as common inductance ballast fluorescent lamp and HID lighting device used in. UPC-D is also adaptive to electronic ballast fluorescent lamp and new-type energy saving system, but energy saving efficiency will be influenced. UPC-D is not suitable for incandescent lamp system because the lighting intensity might be affected when the voltage reduced
3.Aging Status of Lamp UPC-D should be installed after the long-time used lamp of low luminous efficiency is replaced by the new one.
4.Voltage High energy saving level and more prolonged service life will be achieved when UPC-D put into operation, if line-neutral voltage in lighting system is higher than 220V for a long time. But the long-term low line-neutral voltage will influence energy saving level.
5.Lighting Intensity Requested by Surroundings The relative energy saving space becomes smaller when high lighting intensity requested by surroundings. Contrarily, there is more energy saving space in low lighting intensity surroundings. A proper energy saving rate should be chosen in actual working conditions.
6.Actual Lighting Intensity High energy saving level can be obtained when actual lighting intensity is much higher than that of designed.!!spec
