مشخصات و کاربرد منبع تغذیه SIL3 مدل PSS1250-2 شرکت GMI
سیستم منبع تغذیه مدل PSS1250 یک واحد رک 7 اینچی با ارتفاع 4U و بدنه آلومینیومی آنودایز شده است که برای پذیرش حداکثر 2 ماژول منبع تغذیه Plug-in از نوع PSM1250 طراحی شده است.
توجه: ماژولهای PSM1250 در این کد سفارش (Ordering Code) ارائه نمیشوند و باید بهصورت جداگانه تهیه شوند.
هر ماژول PSM1250 قادر است خروجی 24 ولت DC با جریان 50 آمپر را تأمین کند.
این ماژولها میتوانند بهصورت موازی (Parallel) کار کنند و دارای مدارهای تقسیم بار (Load Sharing) هستند که جریان بار را بهطور مساوی بین ماژولهای منبع تغذیه توزیع میکنند. این ویژگی باعث:
- افزایش قابلیت اطمینان (Reliability)
- کاهش تلفات توان داخلی
- کاهش تولید حرارت
- بهبود عملکرد و دسترسپذیری سیستم
میشود.
این سیستم قابلیت اتصال به دو منبع تغذیه AC مستقل را دارد و ولتاژ ورودی در محدوده 110 تا 240 ولت AC با تلرانس ±10٪ پذیرفته میشود.
کاربرد: سیستم منبع تغذیه
