LVP Elevator Board  BASE-3A Elevator Board Two Versions Explained

BASE-3A elevator boards all carry the original part number 2R21209*A, but they are divided into two types based on power rating: one for 5.5KW and the other for 7.5KW-11KW.

In fact, the earliest versions of the board were divided into two part numbers: 2R21209*A and 2R21209*B.

2R21209*A is used for LVP60 elevators with power ratings from 7.5KW to 11KW.

2R21209*B corresponds to elevators with 5.5KW power.

However, in later production, all elevator boards had the part number is 2R21209*A.
