مشخصات و کاربرد منبع تغذیه SIL3 مدل PSS1250-3-D شرکت GMI
سیستم تغذیه مدل PSS1250، یک واحد رک ۹ اینچی (با ارتفاع 4U) از جنس آلومینیوم آنودایز شده است که برای پذیرش حداکثر ۲ ماژول منبع تغذیه کشویی (Plug-in) مدل PSM1250 و یک ماژول “Overview” (برای عملکردهای تشخیصی) طراحی شده است.
هر ماژول قادر است خروجی ۲۴ ولت DC با جریان ۵۰ آمپر ارائه دهد. ماژولها میتوانند با استفاده از مدارهای تقسیم بار (Load Sharing) با یکدیگر موازی شوند؛ این کار باعث میشود جریان بار بهطور مساوی بین ماژولها تقسیم شده، قابلیت اطمینان افزایش یابد و اتلاف توان داخلی کاهش پیدا کند. این سیستم از دو منبع تغذیه AC مستقل از ۱۱۰ تا ۲۴۰ ولت (با ۱۰٪ تلورانس) پشتیبانی میکند.
کاربرد: سیستم منبع تغذیه
