The CTRCT-2 derives voltage feedback from an attenuator connected to the feedback voltage.<\/span><\/li>\n<li><span>Load Current or Voltage Regulation: Limit amplifiers respond to the difference between the either feedback signal and the corresponding limit commands. The resulting signal is the SCR delay angle command signal, SIG HI. The CTRCT2 may be configured to regulate load voltage in addition to providing overcurrent trip.<\/span><\/li>\n<li><span>Overcurrent Trip with Manual or Automatic Reset: A current trip feature inhibits the SCR firing board when the current exceeds the threshold set by the board-mounted potentiometer. This feature shuts down the system in the event of a short circuit . The regulator board may be configured to automatically reset after a predetermined dead time (typically several seconds) or latch until a manual reset is asserted.<\/span><\/li>\n<li><span>Soft-Start Ramp: The CTRCT-2 includes a ramp potentiometer which controls the soft-start ramp time. The soft-start or soft-stop time constants are determined by a resistor and capacitor.<\/span><\/li>\n<li><span>CTRCT-2 Status Interface: The CTRCT-2 includes an auxiliary connector with three open-collector transistors indicating the status of the overcurrent , manual trip, and current limit signals. Connections to the circuit common, +12 and +24 V rails are provided to drive lamps, relay coils, or other monitoring apparatus.<\/span><\/li>\n<li><span>Current Command Signal: The current command signal (or voltage command signal, if configured for the CTRCT-2) may be configured for a variety of common ranges including 0-12 V, 0-10 V, or 4-20 mA.<\/span><\/li>\n<li><span>Board Construction: All circuit boards are assembled at the Enerpro plant in Goleta, California and are manufactured by a UL-approved fabricator from 2.4 mm thick FR4 fire resistant fiberglass epoxy laminate. All boards are conformal coated (MIL-1-46058, Type UR).<\/span><\/li>\n<\/ul>\n[\/et_pb_toggle][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=&#8221;1&#8243; module_class=&#8221;customfooter&#8221; _builder_version=&#8221;3.26&#8243; background_color=&#8221;#2A2A2A&#8221; min_height=&#8221;458px&#8221; custom_padding=&#8221;||0px|||&#8221; global_module=&#8221;131558&#8243; saved_tabs=&#8221;all&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_row column_structure=&#8221;1_5,1_5,1_5,1_5,1_5&#8243; _builder_version=&#8221;4.16&#8243; width=&#8221;90%&#8221; max_width=&#8221;1440px&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_column type=&#8221;1_5&#8243; _builder_version=&#8221;4.16&#8243; global_colors_info=&#8221;{}&#8221;][et_pb_text module_id=&#8221;customfoot&#8221; _builder_version=&#8221;4.16&#8243; text_text_color=&#8221;#ffffff&#8221; text_font_size=&#8221;13px&#8221; text_line_height=&#8221;1.9em&#8221; header_4_text_color=&#8221;#ffffff&#8221; header_4_font_size=&#8221;16px&#8221; header_4_line_height=&#8221;1.2em&#8221; global_colors_info=&#8221;{}&#8221;]\n<h4 class=\"title\">UNITED STATES<\/h4>\n<p>Enerpro, Inc.<br \/> Global Headquarters<br \/> 99 Aero Camino<br \/> Goleta, CA 93117<\/p>\n<p><a href=\"mailto:info@enerpro-inc.com\" target=\"_blank\" rel=\"noopener noreferrer\">info@enerpro-inc.com<\/a><br \/> <a href=\"https:\/\/www.enerpro-inc.com\/\" target=\"_blank\" rel=\"noopener noreferrer\">https:\/\/www.enerpro-inc.com<\/a><\/p>\n<p>Tel: (805) 683-2114<br \/> Fax: (805) 964-0798<\/p>\n[\/et_pb_text][\/et_pb_column][et_pb_column type=&#8221;1_5&#8243; _builder_version=&#8221;4.16&#8243; global_colors_info=&#8221;{}&#8221;][et_pb_text module_id=&#8221;customfoot&#8221; _builder_version=&#8221;4.16&#8243; text_text_color=&#8221;#ffffff&#8221; text_font_size=&#8221;13px&#8221; text_line_height=&#8221;1.9em&#8221; header_4_text_color=&#8221;#ffffff&#8221; header_4_font_size=&#8221;16px&#8221; header_4_line_height=&#8221;1.2em&#8221; global_colors_info=&#8221;{}&#8221;]\n<h4 class=\"title\">CANADA<\/h4>\n<p>ICT Power Company Inc.<br \/>1220 Corporate Dr.<br \/>Burlington, ON L7L 5R6<br \/>Canada<\/p>\n<p><a href=\"mailto:sales@ictpower.com\" target=\"_blank\" rel=\"noopener noreferrer\">sales@ictpower.com<\/a><br \/><a href=\"http:\/\/www.ictpower.com\/\" target=\"_blank\" rel=\"noopener noreferrer\">http:\/\/www.ictpower.com<\/a><\/p>\n<p>Tel: 905.631.8494<br \/>Fax: 905.631.8495<\/p>\n[\/et_pb_text][\/et_pb_column][et_pb_column type=&#8221;1_5&#8243; _builder_version=&#8221;4.16&#8243; global_colors_info=&#8221;{}&#8221;][et_pb_text module_id=&#8221;customfoot&#8221; _builder_version=&#8221;4.16&#8243; text_text_color=&#8221;#ffffff&#8221; text_font_size=&#8221;13px&#8221; text_line_height=&#8221;1.9em&#8221; header_4_text_color=&#8221;#ffffff&#8221; header_4_font_size=&#8221;16px&#8221; header_4_line_height=&#8221;1.2em&#8221; min_height=&#8221;312px&#8221; custom_margin=&#8221;0px||||false|false&#8221; custom_padding=&#8221;7px||0px|||&#8221; global_colors_info=&#8221;{}&#8221;]\n<h4 class=\"title\">SCANDINAVIA<\/h4>\n<p>MPE Cathodic AS<br \/>P.

The CTRCT-2 derives voltage feedback from an attenuator connected to the feedback voltage.<\/span><\/span><\/li><li><span style=\"font-size: small;\">Load Current or Voltage Regulation: Limit amplifiers respond to the difference between the either feedback signal and the corresponding limit commands. The resulting signal is the SCR delay angle command signal, SIG HI. The CTRCT2 may be configured to regulate load voltage in addition to providing overcurrent trip.<\/span><\/li><li><span style=\"font-size: small;\">Overcurrent Trip with Manual or Automatic Reset: A current trip feature inhibits the SCR firing board when the current exceeds the threshold set by the board-mounted potentiometer. This feature shuts down the system in the event of a short circuit . The regulator board may be configured to automatically reset after a predetermined dead time (typically several seconds) or latch until a manual reset is asserted.<\/span><\/li><li><span style=\"font-size: small;\">Soft-Start Ramp: The CTRCT-2 includes a ramp potentiometer which controls the soft-start ramp time. The soft-start or soft-stop time constants are determined by a resistor and capacitor.<\/span><\/li><li><span style=\"font-size: small;\">CTRCT-2 Status Interface: The CTRCT-2 includes an auxiliary connector with three open-collector transistors indicating the status of the overcurrent , manual trip, and current limit signals. Connections to the circuit common, +12 and +24 V rails are provided to drive lamps, relay coils, or other monitoring apparatus.<\/span><\/li><li><span style=\"font-size: small;\">Current Command Signal: The current command signal (or voltage command signal, if configured for the CTRCT-2) may be configured for a variety of common ranges including 0-12 V, 0-10 V, or 4-20 mA.<\/span><\/li><li><span style=\"font-size: small;\">Board Construction: All circuit boards are assembled at the Enerpro plant in Goleta, California and are manufactured by a UL-approved fabricator from 2.4 mm thick FR4 fire resistant fiberglass epoxy laminate. All boards are conformal coated (MIL-1-46058, Type UR).<\/span><\/li><\/ul><p>\u00a0<\/p><p>{tab=Applications|dark grey}<\/p><ul><li><span style=\"font-size: small;\">Battery Chargers<\/span><\/li><li><span style=\"font-size: small;\">Motor Controllers<\/span><\/li><li><span style=\"font-size: small;\">Magnet Power Supplies<\/span><\/li><li><span style=\"font-size: small;\">UPS Systems<\/span><\/li><li><span style=\"font-size: small;\">Transformer Primary Controllers<\/span><\/li><\/ul><p>{\/tabs}<\/p>","_et_gb_content_width":"","footnotes":""},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v22.6 -
