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 CTRCT-2 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; fb_built=&#8221;1&#8243; _i=&#8221;2&#8243; _address=&#8221;2&#8243;][et_pb_row column_structure=&#8221;1_5,1_5,1_5,1_5,1_5&#8243; _builder_version=&#8221;3.26&#8243; width=&#8221;90%&#8221; max_width=&#8221;1440px&#8221; _i=&#8221;0&#8243; _address=&#8221;2.0&#8243;][et_pb_column type=&#8221;1_5&#8243; _builder_version=&#8221;3.26&#8243; _i=&#8221;0&#8243; _address=&#8221;2.0.0&#8243;][et_pb_text module_id=&#8221;customfoot&#8221; _builder_version=&#8221;3.26.6&#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; _i=&#8221;0&#8243; _address=&#8221;2.0.0.0&#8243;]\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\/undefined\/\" target=\"_blank\" rel=\"noopener noreferrer\">https:\/\/www.enerpro-inc.com<\/a><\/p>\n<p>Toll Free: (877) 648-2114<br \/> 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;3.26&#8243; _i=&#8221;1&#8243; _address=&#8221;2.0.1&#8243;][et_pb_text module_id=&#8221;customfoot&#8221; _builder_version=&#8221;3.26.6&#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; _i=&#8221;0&#8243; _address=&#8221;2.0.1.0&#8243;]\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;3.26&#8243; _i=&#8221;2&#8243; _address=&#8221;2.0.2&#8243;][et_pb_text module_id=&#8221;customfoot&#8221; _builder_version=&#8221;3.26.6&#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; _i=&#8221;0&#8243; _address=&#8221;2.0.2.0&#8243;]\n<h4 class=\"title\">MEXICO<\/h4>\n<p>Electronica Integral De Puebla, SA DE CV<br \/> Jose Guadalupe Posada 1413\u00a0col.

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 CTRCT-2 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 -
