مشخصات و کاربرد منبع تغذیه SIL3 مدل PSW1250 شرکت GMI

واحد منبع تغذیه مدل PSW1250 از جنس فولاد ضد زنگ AISI 304 است. این منبع تغذیه خروجی ۲۴ ولت DC با جریان ۵۰ آمپر را فراهم می‌کند. واحد PSW1250 قابلیت موازی‌سازی دارد، همراه با مدارهای اشتراک بار (Load Sharing) که بار جریان را به طور مساوی به هر منبع تغذیه توزیع می‌کنند تا قابلیت اطمینان افزایش یافته و اتلاف توان داخلی کاهش یابد. این منبع تغذیه، منابع تغذیه AC را در محدوده ولتاژ نامی ۱۱۰ تا ۲۴۰ ولت AC (±۱۰٪) می‌پذیرد.

کاربرد: سیستم منبع تغذیه
