VARIABLE FUENTE DE ALIMENTACIÓN DE CA Y CC

Las fuentes regulables de alimentación de PMI, son adecuadas para el uso en diferentes aplicaciones que requieren amplia gama de ajustes para tensión de CA o CC.

Los sistemas de alimentación de corriente alterna y corriente continua se proporcionan por un transformador de aislamiento galvánico.

La sección del rectificador es controlada por tiristor y la sección del inversor es controlada por IGBT que es una característica común de los sistemas de alimentación de PMI.

Las Fuentes Ajustables de Alimentación de PMI, son de tipo industrial, fiables y fácil de proporcionar servicio.
