Sunpower’s PCC LED Constant Current Power Supply Series features Triac dimming

Sunpower UK’s PCC Series of RoHS compliant constant current single-output power supplies are designed for indoor LED lighting applications. The Series features mains 1-100% Triac dimming, which is highly attractive to both installers and users as it eliminates the need for secondary cables and complex dimming systems. This combination of Triac dimming and constant current output has previously been extremely hard to source – and impossible from such attractively-priced, small footprint products. Easy installation with no compatibility issues or concerns is assured as the PCC’s dimming function has been successfully tested as applicable with every known leading- and trailing-edge dimmer.

Installation effort is further reduced by snap lock cable strain relief, and by captive screws which allow easy connection. The PCC Series is electrically efficient, and offers a high power factor of 0.9 or better. Units are available with 9 W, 18 W and 36 W ratings. They accept a 220 – 240 Vac input and offer a choice of 350 mA – 1400 mA constant current outputs. The PCC Series is short circuit protected, tolerates an overload to 135% of rated power and features thermal shutdown for over temperature conditions. The Class ll product design is referred to EN61347-1:2001 and EN61347-2-13:2001 safety standards, and complies with relevant EMC Emissions and Immunity requirements. Cooling is by free air circulation.

The benefits of the PCC Series for indoor LED lighting applications have been recently demonstrated by Xicato, an innovative luminaire manufacturer with facilities in the US, the UK and Tokyo. Xicato develops, manufactures and globally markets LED modules that are simple functional replacements for traditional lamp technologies, offering all the life and energy-saving advantages of LEDs with no aesthetic compromises. Xicato’s product lineup includes XSM spotlight modules and XLM linear lights, and they have tested and approved a set of PCC products as suitable drivers for these. As a result, the company has developed a Driver Compatibility Matrix detailing which, and how, PCC, XSM and XLM products can be used together. This Matrix is distributed to their OEM customers world-wide.

The PCC Series range of constant current Triac dimming power supplies is ideal for indoor LED lighting applications including residential LED lighting, display cases, LED downlights, LED backlighting, mood lighting and light sculptures.
