مشخصات و کاربرد منبع تغذیه SIL3 مدل PSS1250-7-2-D شرکت GMI

سیستم منبع تغذیه نوع PSS1250 یک واحد رک ۱۹ اینچی (با ارتفاع 4U) از جنس آلومینیوم آنودایز شده است که برای پذیرش حداکثر ۶ ماژول منبع تغذیه کشویی نوع PSM1250 و ۱ ماژول Overview جهت انجام وظایف تشخیصی مناسب می‌باشد. هر ماژول قادر به ارائه خروجی ۲۴ ولت DC با جریان ۵۰ آمپر است. ماژول‌ها می‌توانند به‌صورت موازی و با استفاده از مدارهای اشتراک بار (Load Sharing) به هم متصل شوند؛ این مدارها بار جریان را به‌طور مساوی بین هر ماژول منبع تغذیه توزیع می‌کنند تا قابلیت اطمینان افزایش یافته و اتلاف توان داخلی کاهش یابد. این سیستم حداکثر از دو منبع تغذیه AC مستقل با ولتاژ ۱۱۰ تا ۲۴۰ ولت AC (±۱۰٪) پشتیبانی می‌کند.

کاربرد: سیستم منبع تغذیه
