Acepta una entrada de sensado de 85\u2013140 V AC (monof\u00e1sico, 2 hilos) con tomas de voltaje en 0\u2013110 V (95\u2013140 V), 0\u2013220 V (170\u2013260 V) y 0\u2013380 V (340\u2013520 V). El suministro en derivaci\u00f3n es de 150 V a 50\/60 Hz. El R449 entrega una salida continua de 63 V DC a 3.5 A (monof\u00e1sico, 120 V). La corriente nominal de sobrecarga es de 15 A por 10 segundos.<\/p>\n<p>La protecci\u00f3n electr\u00f3nica integrada cubre sobrecarga, cortocircuito y p\u00e9rdida de sensado \u2014 si la corriente de excitaci\u00f3n supera 10 A por m\u00e1s de 10 segundos, cae autom\u00e1ticamente a aproximadamente 1 A y requiere parar el generador para reiniciarse. La unidad incluye ajuste de voltaje mediante potenci\u00f3metro P2, ajuste de ca\u00edda en cuadratura mediante P1, y ajuste del punto de rodilla de baja frecuencia (U\/F) mediante P4 para sistemas de 50 y 60 Hz. El rango de ajuste de sobreintensidad de excitaci\u00f3n es de 4.5 a 15 A.<\/p>\n","protected":false},"excerpt":{"rendered":"<ul>\n<li><strong>Regulador de Voltaje Autom\u00e1tico<\/strong> \u2014 Reemplazo gen\u00e9rico exacto para R449<\/li>\n<li><strong>Regulaci\u00f3n de voltaje en estado estacionario:<\/strong> \u00b10.5%<\/li>\n<li><strong>Capacidad de cortocircuito:<\/strong> 3 \u00d7 I nominal por 10 segundos (excitaci\u00f3n AREP o PMG)<\/li>\n<li><strong>Sensado de voltaje:<\/strong> terminales 0-110V (95\u2013140V), 0-220V (170\u2013260V) o 0-380V (340\u2013520V), 50\/60 Hz<\/li>\n<li><strong>Tiempo de respuesta:<\/strong> Normal (1 seg) o R\u00e1pido (0.3 seg) \u2014 Ajuste remoto de voltaje: \u00b15%<\/li>\n<\/ul>\n","protected":false},"featured_media":15716,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_et_pb_use_builder":"","_et_pb_old_content":"","_et_gb_content_width":"","_joinchat":[]},"product_brand":[],"product_cat":[233],"product_tag":[238,240,241,1060],"class_list":["post-5311","product","type-product","status-publish","has-post-thumbnail","product_cat-avr-leroy-somer","product_tag-avr","product_tag-generic-regulators","product_tag-leroy-somer","product_tag-r449-avr","pa_marca-leroy-somer","pa_serie-r449","first","instock","taxable","shipping-taxable","product-type-simple"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.1 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>AVR R449 generador | Power Master Inc.<\/title>\n<meta name=\"description\" content=\"Compra el AVR R449 \u2014 regulador de voltaje autom\u00e1tico original Leroy Somer.
