Harvard Technology, world leader in the design, development and manufacture of wireless control solutions for lighting, has launched its latest innovations in the CoolLED programmable driver range, adding both a 40W and 50W Dali Low Voltage SELV variant in the CLS case platform to what is a growing programmable range. 


The power factor corrected, fully isolated SELV output Dali drivers, are initially available in two variants – 200-700mA and 700-1400mA – delivering up to 40W and 50W of power respectively. 


Uniquely, the innovative drivers support smooth linear dimming over the entire output range with low output ripple, and enable users to programme the output current by either resistive or software programming.


Surge protected up to 4kV, the new generation CoolLED drivers boast a highly efficient design that delivers significant energy savings. Drive efficiency performance at 88%, at full load, optimises cool operation, longer life and class leading system efficacy. Flicker is also reduced to a minimum due to the driver design. Image removed.


A wide input voltage range makes the programmable drivers suitable for a variety of applications including, but not limited to, commercial offices, education establishments, retail, warehousing and manufacturing.


The new drivers can be easily implemented as part of a wireless lighting controls solution, and are fully compatible with Harvard Technology’s award winning wireless control and management system, EyeNut.


The well established range of Harvard Technology programmable drivers also includes a CLK software programmable solution that enables users to programme a driver in 1mA increments from 100mA to 1050mA. The simple user interface allows for fast programming – with no more than two seconds per driver. 


An adjustable lumen output means the CLK 33W LED driver provides a high performance solution for powering LEDs from a mains supply. In addition, the low profile, universal input CLX is available in 40W and 50W variants. The driver has full dimming capabilities from 100% down to 1% and can be turned off completely. It also benefits from low output ripple for flicker free light. The driver is programmable both via the software jig and RFID.


Tim McKernan, head of OEM sales at Harvard Technology, said, “We are delighted to have further enhanced our CoolLED programmable driver range. The addition of theCLS40 and CLS50 DALI Low Voltage SELV drivers to our family of CLS driver solutions further highlights our position as a market leader. The CLS range are perfectly placed within linear applications and can be used in conjunction with our high performing range of LEDeng light engines. The drivers also enable a level of programmability that has not previously been attainable.”


“Allowing freedom to control the output power of your LED driver in any configuration you wish, our unique software programmable drivers are high performing, feature rich and have unparalleled efficiencies. Available in three driver footprints, suitable across a wide range of applications and with two different ways to programme, we have a solution to fit all requirements.”
