high energy condenser discharge ignition
Digital advance predefined switch selectable advance profiles. advance of either 20° or 16° advance at unit shaft (that is 40° resp. 32° crankshaft advance). For graph look here
advance may be modified by about 10° after installation without changing chain or gear settings from unit to engine by shifting internal pickup
regulated lighting voltage of 14.4V (that is standard for 12V systems) with 60W load already at 1.000rpm 35W (diagram).
may be used without battery, but will need in that case a high capacity condenser to enable correct regulator functioning
