摘要： An adjustable brake controller of an elevator brake including a DC bus, first terminals for connecting the brake controller to a first magnetizing coil, second terminals for connecting the brake controller to a second magnetizing coil, a first controllable power switch coupled between the first terminals and the DC bus, the first controllable power switch being configured to supply electric power from the DC bus to the first magnetic coil responsive to a first control signal, a second controllable power switch coupled between the second terminals and the DC bus, the second controllable power switch being configured to supply electric power from the DC bus to the second magnetizing coil responsive to a second control signal, and a controller configured to generate the first and the second control signals for controlling the first and second power switches, respectively, with a brake open mode and a brake holding mode.
