BOM - Bill Of Material
Inverter Kit » Schematics and Instructions » Archived Instructions » BOM - Bill Of Material
These BOMs apply to all kits with the large sensor board that were shipped until January 2018. The kits thereafter contain a printed BOM.
The tables below list all parts that go on the PCB. The "ID" column references the part as designated on the part sheet.

Populate R1-R5 depending on your needs. The formular for the maximum DC voltage is
R1-R4 should be in the meg-Ohms region and R5 should be sized for the maximum desired DC voltage. The provided resistors allow a maximum voltage of 900V.

Two extra 680k resistors are provided for high voltage applications (say, above 300V). Place them off board e.g. inline with the measurement leads. On the revision 2 boards they go on board.
* Only revision 3 board
** Only when using LEM HTFS current sensors
