The resulting signal is the SCR delay angle command signal, SIG HI.<\/li>\n<li>Current and Voltage Limit Automatic Crossover: A diode OR circuit provides automatic crossover between voltage and current limiting. The ISOVLCL -4 operates in either current or voltage regulating mode depending on which limit command setting is lowest.<\/li>\n<li>Overcurrent and Overvoltage Trip with Manual or Automatic Reset: Two board-mounted potentiometers set the current and voltage trip levels. A trip resets the soft-start circuit; its response time to an overcurrent or overvoltage event is approximately 3 milliseconds.\u00a0 If this condition persists, the overcurrent or overvoltage trip will automatically reset and trip, cycling continuously until cleared.<\/li>\n<li>Adjustable Soft-Start: The ISOVLCL-4 includes a potentiometer-adjustable soft-start ramp.<\/li>\n<li>Polarity Reversing Compatibility: The current and voltage feedback signals are processed by precision absolute value circuits, avoiding positive feedback and permitting operation with polarity reversing applications.<\/li>\n<li>Voltage and Current Read-Back Signals: Scaled analog voltage and current signals are available from a dedicated connector.<\/li>\n<li>Status Interface: The ISOVLCL-4 includes an auxiliary connector with four open-collector transistors indicating the status of the overcurrent , overvoltage, manual trip, and current limit signals. Connection to common, +12 and 24 V rails are provided to drive lamps, relay coils, or other common apparatus.<\/li>\n<li>Onboard or Offboard Voltage and Current Commands: Users may command the desired voltage or current level using board-mounted potentiometers or through externally applied voltage and current commands. Several command voltage or current ranges are available, including 0-12 V, 0-10 V, and 4-20 mA.<\/li>\n<li>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).<\/li>\n<\/ul>\n<p>Enerpro applications engineers are available by e-mail or fax for applications assistance.<\/p>\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 resulting signal is the SCR delay angle command signal, SIG HI.<\/span><\/li><li><span style=\"font-size: small;\">Current and Voltage Limit Automatic Crossover: A diode OR circuit provides automatic crossover between voltage and current limiting. The ISOVLCL-3 operates in either current or voltage regulating mode depending on which limit command setting is lowest.<\/span><\/li><li><span style=\"font-size: small;\">Overcurrent Trip with Automatic Reset: A board-mounted potentiometer sets the current trip level. The current trip resets the soft-start circuit; its response time to an overcurrent event is approximately 3 milliseconds. If the over-current condition persists, the current trip will automatically reset and trip, cycling continuously until cleared.<\/span><\/li><li><span style=\"font-size: small;\">Soft-Start and Soft-Stop: The soft-start circuit ramps the gate delay command voltage input to the firing board up to the preset level in approximately 2 seconds; the soft-stop ramps the command down in a similar fashion. Other soft-start times may be specified. <br \/><\/span><\/li><li><span style=\"font-size: small;\">Polarity Reversing Compatability: The current and voltage feedback signals are processed by precision absolute value circuits, avoiding positive feedback and permitting operation with polarity reversing applications. <br \/><\/span><\/li><li><span style=\"font-size: small;\">Voltage and Current Read-Back Signals: Scaled analog voltage and current signals are available from a dedicated connector. <br \/><\/span><\/li><li><span style=\"font-size: small;\">Onboard or Offboard Voltage and Current Commands: Users may command the desired voltage or current level using board-mounted potentiometers or through externally applied voltage and current commands. Several command voltage or current ranges are available, including 0-12 V, 0-10 V, and 4-20 mA. <br \/><\/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;\">Electro-chemical Process Power Supplies<\/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><\/ul><p>{\/tabs}<\/p>","_et_gb_content_width":"","footnotes":""},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v22.6 -
