AMG-LL7AXX family of hv led driver modules 1. functional description of the AMG-LL7AXX the AMG-LL7AXX is a famiy of non isolated high voltage led driver modules. the family consists out of a master and slave modules. a complete system can consist out of 1 master and up to 2 ll7a7-9 (1500ma) or 4 ll7a4-6 (700ma) or 8 ll7a1-3 (350ma) slave modules. the modules can be stacked up to form a line, a stack, a curve or other shapes. for all shapes other than the line an interconnection cable is necessary. a 0-10v dimmer, analog voltage or potentiometer can be connected to the master module for dimming. the modules will go into low power shut down mode at dimming voltages below 1.2v. each module has two shunt resistors, which allow for further adjustment of the led current. the nominal current will be supported by two shunt resistors. this is the factory setting. by removing one of the shunts, the maximum led current will be reduced. 2. features ? ac mains supply ? low current ripple <10% ? short circuit/over current protection ? wide output voltage range ? output power up to 15/30/63w ? power factor >0,85 ? dimmable (0-10v) ? fast wire to board connections (stackable modules) ? small form factor (147 x30mm) ? very slim module (<16mm) ? wide temperature range (-20 => 85c) 3. application the AMG-LL7AXX are suitable for many led lighting applications such as: ? led backlighting ? illumination ? led light fixtures ? decorative lights ? security lights ? industrial lighting ? aircraft + watercraft lights ? dimmable (0-10v) amg- ll7axx revision: a 11. apr. 2012 ? all rights reserved page 1 of 14

AMG-LL7AXX family of hv led driver modules 10.3. application notes a) considerations on heat dissipation... tbd b) considerations on led-string forward voltage and efficiency... tbd c) considerations on led-string forward voltage and current ripple... tbd d) modification of max. string current the maximum string current is set by two shunt resistors on the slave modules. the two shunts are in parallel and combined provide the highest current setting for the board. removing either one will lower the maximum string voltage of that particular slave module. slave module shunts 1+2 present shunt 1 present shunt 2 present ll7a1-3 350ma 200ma 150ma ll7a4-6 700ma 500ma 200ma ll7a7-9 1500ma 1000ma 500ma one shunt on the slave boards can be removed with a soldering iron to further reduce the maximum string current if desired. e) dimming... a 0-10v dimmer can be attached to the master module. both linear and logarithmic dimming curves will work. logarithmic dimming curves usually are more appealing to the eye. care needs to be taken, that the dimmer is connected with it's positive and negative connectors correctly to the master module. it is also possible to connect a 3k potentiometer or a galvanically isolated 0-10v source instead of a dimmer. all slave modules which are connected to that particular master module will all simultaneously be dimmed from that one connected dimmer. if the dimming input is left open, the slave modules will work with their highest current setting. no open ended wires should be connected to the dimmer input of the master module. wiring from the master module to the dimmer should not run parallel to mains lines. this can cause flicker, particularly at the lower dimming end. high voltage (>15v) provided to the dimmer connector will potentially destroy the master and all connected slave modules. 11. module dimensions 11.1. master length = 147mm (may change) width = 30mm height < 16mm amg- ll7axx revision: a 11. apr. 2012 ? all rights reserved page 11 of 14
