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

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)

3.2. Application Notes
The module can be operated directly off the mains. As such, all applicable safety rules and
guidelines have to be observed. Specifically, but not limited, during test and evaluation.
Warning, High Voltage!
Caution, exposed voltage on the circuit board. Working with line voltage is dangerous!
Electrical shock above 42V can be life threatening! Use only under the supervision of
qualified personnel! Caution, use only in a laboratory environment! Ensure all
applicable safety regulations are observed.
