● The default initial braking voltages of built‑in braking units are 760 V and 350 V for
the 380‑480 V models and 200‑240 V models, respectively.
● The default initial braking voltage of the external braking units MDBUN‑60‑T,
MDBUN‑90‑T, and MDBUN‑200‑T is 670 V. These braking units apply to grids with
