A fonte de alimenta\u00e7\u00e3o CA PWM LSP-5KVAS possui caracter\u00edsticas de distor\u00e7\u00e3o de tens\u00e3o de sa\u00edda ultrabaixa e valor de prote\u00e7\u00e3o de corrente de sa\u00edda configur\u00e1vel. Ela foi especialmente desenvolvida para eletrodom\u00e9sticos, motores, compressores e outras aplica\u00e7\u00f5es industriais. Utilizada para substituir reguladores de tens\u00e3o e conversores de frequ\u00eancia tradicionais, oferece solu\u00e7\u00f5es de teste eficientes, econ\u00f4micas e precisas. Possui quatro rodas para facilitar o transporte entre ambientes.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

\n1. Os pa\u00edses que seguem os padr\u00f5es dos EUA podem projetar a tens\u00e3o de entrada de forma espec\u00edfica. Por exemplo, entrada monof\u00e1sica e sa\u00edda monof\u00e1sica (LSP-10KVASUS) significam que tanto a entrada quanto a sa\u00edda s\u00e3o 110V\u00b110%;
\n2. Por exemplo, LSP-15KVASUST com entrada trif\u00e1sica e sa\u00edda trif\u00e1sica significa que tanto a entrada quanto a sa\u00edda s\u00e3o 220V\u00b110%.<\/span><\/p>\n
