An adjustable brake controller (50) of an elevator brake (1) comprises - a DC bus (B); - first terminals (159, 259) for connecting the brake controller (50) to a first magnetizing coil (9, L1); - second terminals (359, 459) for connecting the brake controller (50) to a second magnetizing coil (9, L2); - a first controllable power switch (155) coupled between the first terminals (159, 259) and the DC bus (B), the first controllable power switch (155) being configured to supply electric power from the DC bus (B) to the first magnetic coil (9, L1) responsive to a first control signal (BW2A); - a second controllable power switch (255) coupled between the second terminals (359, 459) and the DC bus (B), the second controllable power switch (255) being configured to supply electric power from the DC bus (B) to the second magnetizing coil (9, L2) responsive to a second control signal (BW2B); and - a controller (60) configured to generate the first and the second control signals (BW2A, BW2B) for controlling the first and second power switches (155, 255), respectively. The controller (60) has: o a brake open mode, wherein the first and second control signals (BW2A, BW2B) have a same specified pattern, and o a brake holding mode wherein the first and second control signals (BW2A, BW2B) have a different specified pattern.
