Compact LED driver range features TRIAC dimming option and easy installation

Sunpower (UK)’s new indoor range of LED drivers makes LED lighting more than ever the natural choice for domestic, commercial and industrial installations. Key to this new range is the AC Dimming (or phase cut) LED Driver product, which features compatibility with ordinary TRIAC dimmers. This makes 1 – 100% dimmable LED lighting as easy to install as traditional conventional dimming lights. Unlike earlier designs, these drivers require just a simple leading edge dimmer for dimming control, eliminating the need for external DC control circuits and additional installation rewiring. The dimming LED Driver’s output voltage and current variants give contractors a wide choice of easy to install LED driving options.
This completely new extension to Sunpower’s LED driver lineup comprises a new wave of the PCC Constant Current and PCV Constant Voltage Driver ranges as well as the AC Dimming LED Drivers. This allows an optimum mix of product outputs, voltages and functionality to fulfil projects of any size. The easily installed Dimming theme is echoed by the drivers’ standalone compact package design. Designed with an easy-press cable lock and captive screw terminal arrangement to simplify installation, the units weigh from as little as 50 g, and with a 50,000 hours service lifetime – over 11 years at 12 hours a day operation – maintenance costs are sharply reduced as well.

Safety and compliance issues are also fully covered. All products are SELV (Separated Extra Low Voltage) equivalent and IEC Protection Class ll insulated. They feature safe no-load operation, and have overload, short-circuit and overheating protection. They are certified to EN 61347-1 and EN 61347-2-13 safety standards as well as EN 55015, EN 61000-3-2, EN 61000-3-3 and EN 61547 EMC limits.

All of the products work from a 220-240 VAC mains supply, and most will accept mains inputs from 100 to 240 VAC. Output power ratings from 3 W to 17 W are available, and the Constant Current range has an option with 2 – 34 VDC variable output and other output voltage limits. The Constant Voltage range has various output ratings in 12 V and 24 V output options, and the constant current dimming range has different variable output voltage options with lower limits from 9 V and upper limits to 32 V. Nearly all the range have an operating temperature span of -20 to +50˚C.
