Ballast / Driver Unit parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.
#PartQtyWhat it does
1 Power Supply 1× AC-DC front end
2 Ballast PCB 4 parts 1× Current-regulation stage
3 Output Choke 1× Arc-stabilising inductor
4 Thermal Fuse 1× One-shot cutoff that opens if a heating appliance overheats.
5 Connector 4× Mating plug-and-socket pair that joins two lengths of wiring or a cable to a board so a circuit can be assembled, serviced, and separated without soldering.
