摘要（英）：

The invention provides an elevator brake power supply which comprises a rectifying and filtering module electrically connected with the input end of a power supply, a voltage converting module electrically connected with the rectifying and filtering module, an output module electrically connected with the voltage converting module, a comparator unit electrically connected with the output module, used for comparing an output voltage with a reference voltage and outputting the voltage comparing result and further used for comparing an output current with a reference current and outputting a current comparing result, and a photoelectrical isolation module electrically connected with the output end of the comparator unit and used for controlling the electrical connection or disconnection between the output module and a brake according to the voltage comparing result and/or the current comparing result. By means of the elevator brake power supply, it can be avoided that a brake power supplyor load is damaged by a too large voltage or current, and the safety and reliability of the elevator brake power supply are improved.
