              Rise ramp<\/em>
              \nIt is possible to set a rise time for the direct voltage to achieve a controlled increase of the working current at the start of the process. Adjustable.<\/p>\n

              Pulsed operation<\/em>
              \nFor all or only a certain phase of the work cycle, it is possible to provide pulsed current delivery. The adjustable parameters are the pulse amplitude (limited by the rectifier\u2019s rated value) and the pulse duration time. The pulse time is typically set between 200\u2013800 ms. Faster pulses are affected by the inductance of the connection to the tank and are increasingly attenuated as the pulse speed increases.<\/p>\n

              Constant current operation<\/em>
              \nIn constant voltage\/current operation, the rectifier stabilizes the set voltage or current against variations in mains voltage and load. Constant voltage\/current operation can be applied for the entire work cycle or for part of it.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][mk_padding_divider][\/vc_column][\/vc_row][vc_row css=”.vc_custom_1746457474336{padding-top: 40px !important;padding-bottom: 40px !important;background-color: #33495B !important;border-radius: 20px !important;}”][vc_column][vc_row_inner][vc_column_inner offset=”vc_col-lg-9 vc_col-md-9″][mk_padding_divider size=”10″][mk_fancy_title tag_name=”h3″ color=”#ffffff” size=”28″ force_font_size=”true” size_smallscreen=”28″ size_tablet=”26″ size_phone=”26″ font_weight=”500″ txt_transform=”none” margin_bottom=”0″ font_family=”none”]WOULD YOU LIKE MORE INFORMATION ABOUT CAEV PRODUCTS?[\/mk_fancy_title][\/vc_column_inner][vc_column_inner offset=”vc_col-lg-3 vc_col-md-4″][mk_button dimension=”flat” corner_style=”rounded” size=”large” url=”https:\/\/www.caev.it\/en\/contact\/” align=”center” margin_bottom=”0″ bg_color=”#81848e” btn_hover_bg=”#ffffff” btn_hover_txt_color=”#33495b”]CONTACT US[\/mk_button][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row][vc_row][vc_column][mk_padding_divider][\/vc_column][\/vc_row]\n<\/div>","protected":false},"excerpt":{"rendered":"
