The overboosting device permits further to sustain excitation current in case of large or sudden overloads, such as starting of A.C. motors. Shunt type AVR do not normally permit to sustain permanently a large fault current such as necessary to let protection devices act: in that case the addition of overboosting systems, such as VARICOMP, permits to maintain the 3-phase short circuit current over 2.5 times the rated current.<\/p>\n<p><strong>Technical Data:<\/strong><\/p>\n<ul>\n<li>RATED VOLTAGE : <span style=\"font-size: 16px; font-style: normal; font-weight: 400;\">220 V<\/span><\/li>\n<li>INPUT CURRENT : 5 A (max, continuous)<\/li>\n<li>INPUT CURRENT : 15 A (max forcing one minute)<\/li>\n<li>OUTPUT CURRENT (DC): 6 A (max, continuous)<\/li>\n<li>OUTPUT CURRENT (DC): 16 A (max forcing one minute)<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<h6>Marelli Spares Varicomp<\/h6>\n","protected":false},"featured_media":1854,"template":"","meta":{"site-sidebar-layout":"default","site-content-layout":"default","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"product_brand":[],"product_cat":[108],"product_tag":[125,51,52,53,110],"class_list":{"0":"post-1805","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-varicomp-module","7":"product_tag-m25fa870a","8":"product_tag-marelli","9":"product_tag-marellispares","10":"product_tag-spare-parts","11":"product_tag-varicomp","12":"desktop-align-left","13":"tablet-align-left","14":"mobile-align-left","16":"first","17":"instock","18":"taxable","19":"shipping-taxable","20":"purchasable","21":"product-type-simple"},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.4 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>M25FA870A - Varicomp - One Stop Shop Online - Marelli spare parts<\/title>\n<meta name=\"description\" content=\"Complete sourcing for Marelli generator spare parts.
