dimming moduleThis compact dimming module is an add-on for the GLV constantvoltage type LED Driver. Featuring a revolutionary snap-on
design, the GLV powering platform can be easily upgraded withdimming for constant current or constant voltage applications.
0-10V/1-10V/Switch Dim, and DALI type dimming modes
supported.
