LASER CUTTER AND SAFE POWER SYSTEM THEREFOR

A laser cutter and safe power system therefor are disclosed. The power system of the laser cutter includes a resistive device arranged in a return line and configured to prevent anomalous tripping of a GFCI device by significantly minimizing electrical noise transmitted through the GFCI device when the laser cutter is operated in certain modes, such as a pulsing mode. The resistive device includes end caps that form a shroud around the connection between a return wire and the contact at each end of the resistive device. A main control board for a high voltage subsystem of the power system includes two isolated and independent enable signals, which are provided to different controllers on the main control board such that the different controllers can independently and redundantly respond to an unsafe condition. 一种激光切割机和用于其的安全电力系统。所述激光切割机的所述电力系统包括电阻装置，所述电阻装置布置在返回线中，并且配置为当所述激光切割机在诸如脉冲模式的某些模式下操作时，通过显著最小化通过GFCI装置发送的电噪声来防止所述GFCI装置的异常跳闸。所述电阻装置包括端帽，所述端帽围绕在所述返回线与所述电阻装置的每个端部处的触点之间的连接形成护罩。用于所述电力系统的高电压子系统的主控制板包括两个隔离且独立的使
