What can OEM designers anticipate in power supplies and related power equipment, and how can they contribute to product success in today’s conditions, asks Andy Wall, Sunpower

LED Flexi Strips now allow lighting designers to offer highly versatile and attractive lighting solutions for retail, commercial and domestic settings. Installers and users can be creative in generating strikingly lit spaces, whether to highlight a commercial product or create a mood for a party. These possibilities are in part due to the design of the flexi strips themselves.

250W AC/DC LED power supplies, which deliver high output currents even at high output voltages, have been released by Sunpower. The HLG-240H-C series, manufactured by Mean Well, feature universal 90-305 VAC inputs for use with 277VAC American industrial mains supplies. Operating with efficiencies of up to 93%, the power devices feature an active PFC function, which raises their power factor to 0.95. 

Andy Wall, CEO of Sunpower Technology, looks at the issue of LED inrush current and how to allow for it within an overall lighting system design.

Sunpower are pleased to announce today the release of the GS280 Series, a single output desktop adapter offering 280 Watts of power, a very low no load power consumption and up to 94% of high efficiency.

Offering 150W of power, built-in two stage PFC function and possessing 4KV surge immunity therefore complying to the requirements of street lighting (EN61000-4-5).

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...

Sunpower’s Power LED PLEC-120SxxxDT driver family has been approved to the UL 8750 safety standard. This international standard underwrites the family’s LED lighting role, as it is specifically written for solid state lighting in a wide range of applications, many in demanding environments. The units have a -35˚C to +65˚C operating temperature range with no output derating.

Sunpower’s PLEC-035S035DT power supply provides up to 100 VDC output at 350 mA. Its constant current capability makes it ideal for driving large LED lighting arrays. This 35 W supply automatically delivers a consistent, optimum current into a series string of any length from 9 to 28 LED lamps. Parallel LED strings can also be added, subject to the total output current capacity of the power supply. LED brightness can be set by a dimming control...

The Sunpower SPV Power Supply range is ideal for applications demanding highly controllable DC power. With power possibilities from 150W up to 4500W, the SPV outputs can be remotely trimmed over a very wide range – from 20% to 110% (120% for SPV-1500) of their nominal value of 12, 24 or 48VDC. The input specification is similarly flexible, with a wide range of AC and DC sources accepted.

Sunpower’s fanless DIN rail power supply family is ideal for applications ranging from industrial automation to domestic appliances. With output ratings from 10W up to 960W, these products efficiently match the power requirements of most panel builders.
