The LXMG1643-12-62 inverter is intended for panel assemblies with individual lamp connections, or where lamps are spaced apart from each other. The LXMG1643-12-61 inverter should be used for panel applications where lamp pairs are in close proximity and share a common return (low side) wire. Other benefits of this new topology are stable fixed-frequency operation, secondary-side strike-voltage regulation and both open/shorted lamp protection with fault timeout.
