Enhanced hybrid dimming from Helvar

Hybrid dimming graph news 30102015_0.jpg

New Helvar drivers have hybrid dimming capabilities which enable good quality light on 1% – 100% dimming levels.

The new Helvar hybrid dimming LED driver LL1x110-E-DA has enhanced dimming performance. On 20% – 100% range, current reduction dimming is used.

The PWM dimming on the 1% – 20% range has been improved. Now on the 10% – 20% range, the PWM frequency is 8 kHz, and on the 1% – 10% range, the frequency grows gradually from 1 kHz to 8 kHz. The technology ensures high quality of light in full dimming range of 1% – 100%.


Helvar launches new LL1x110-E-DA Dimmable DALI LED driver with enhanced hybrid dimming. In addition it has the following superior features:


Energy efficiency (max) 0.95
Standby power <0.5 W
Lifetime 55,000 h @ Tc max 75 ºC
(or > 100,000 h if the luminaire is designed to ensure that the Tc point temperature stays under 65 ºC)
Constant Lumen Output* YES
Current setting With a current setting resistor or through DALI channel**

* Constant Lumen Output (CLO): when the modules age, they lose their luminance. The driver can keep the lumen output constant through the whole life cycle of the luminaire.

** With Helvar 510 Serial interface, the driver can be connected to a PC running Helvar DALI configurator, to modify the driver's current settings
