Thiết bị cấp nguồn khẩn cấp VX-2000DS

Âm thanh thông báo cũng giống như những dàn âm thanh khác, đều bao gồm thiết bị thu âm thanh, khuếch đại và phát âm thanh và đặc biệt, một hệ thống âm thanh thông báo chuyên nghiệp không thể thiếu một thiết bị cấp nguồn. Bài viết dưới đây Thế giới âm thanh giới thiệu đến bạn thiết bị cấp nguồn khẩn cấp VX-2000DS.

ĐẶC ĐIỂM NỔI BẬT

Thiết bị cấp nguồn khẩn cấp VX-2000DS là 1 trong 24 sản phẩm thuộc hệ thống âm thanh TOA VX-2000 – là hệ thống thông báo di tản khẩn cấp phù hợp hoàn toàn với tiểu chuẩn EN54 của liên minh châu Âu (EU) về hệ thống báo cháy và hệ thống PA thông báo chung.

Thiết bị này cung cấp nguồn DC tới từng thiết bị trong hệ thống VX-2000 thông qua kết nối với bộ cấp nguồn VX-200PS. Thiết bị này cho phép kết nối với 2 bộ ắc quy 12V và tự động sạc ắc quy và khi nguồn DC từ VX-200PS bị mất, thiết bị cấp nguồn khẩn cấp VX-2000DS sẽ tự động chuyển sang ắc quy dự phòng.

Thiết bị có bề mặt được làm từ chất liệu là thép tấm sơn đen, độ bóng 30%, với kích thước 482 (R) × 88.4 (C) × 377.6 (S)mm và trọng lượng 10.5 kg. Thiết bị này bao gồm 1 ngõ vào nguồn, 1 ngõ ra nguồn và 1 cổ điều khiển:

+ Ngõ vào nguồn: cung cấp 6 cặp ốc M4, khoảng cách: 11mm

+ Ngõ ra nguồn DC: 6 cặp ốc M4 ( 24 A tối đa), khoảng cách giữa các ốc: 11mm

+ Cổng điều khiển: cổng RJ45 cái cho kết nối với khung gắn thiết bị giám sát VX-2000SF, kiểu cáp xoắn đôi (Chuẩn TIA/EIA-586A)

Với thiết kế hiện đại – đơn giản nhưng vẫn thể hiện đc sự cuốn hút ngay từ cái nhìn đầu tiên VX-2000DS phù hợp với mọi không gian lắp đặt. Ngoài ra, với nhiệt độ hoạt động là 0 ℃ tới +40 ℃, thiết bị cấp nguồn khẩn cấp VX-2000DS có thể hoạt động bền bỉ dưới điều kiện thời tiết xấu.
