2. Đặc điểm nổi bật của công tơ điện tử 1 pha Emic CE38
✅ Đo lường chính xác – hiển thị rõ ràng
Công tơ CE38 thuộc cấp chính xác 1.0, đảm bảo sai số thấp trong suốt quá trình vận hành. Màn hình LCD lớn, hiển thị rõ ràng các thông số điện như:
. Sản lượng điện tiêu thụ (kWh)
. Dòng điện (A)
. Điện áp (V)
. Tần số (Hz)
. Công suất tiêu thụ (W)
. Hệ số công suất (cosφ)
✅ Lưu trữ dữ liệu lâu dài
Công tơ CE38 có khả năng lưu trữ dữ liệu lịch sử tiêu thụ điện đến 12 tháng, hỗ trợ người dùng truy xuất lại dữ liệu cũ để đối chiếu hoặc kiểm tra.
✅ Hoạt động ổn định trong môi trường khắc nghiệt
Thiết kế chắc chắn, chịu được nhiệt độ cao, độ ẩm, bụi – Công tơ điện tử 1 pha Emic CE38 đảm bảo hoạt động ổn định trong điều kiện khí hậu nhiệt đới như tại Việt Nam.
3. Nguyên lý hoạt động của công tơ điện tử 1 pha Emic CE38
Công tơ CE38 sử dụng vi xử lý (MCU)để thu thập tín hiệu dòng điện và điện áp đầu vào. Tín hiệu này được:
. Biến đổi tương tự – số (ADC)
. Tính toán công suất tiêu thụ tức thời
. Tích hợp thành điện năng tiêu thụ (kWh)
. Lưu trữ vào bộ nhớ không mất dữ liệu khi mất điện
Các thông số được hiển thị trên màn hình LCD và đồng thời có thể truyền đi qua cổng hồng ngoại hoặc RS485.
4. Hướng dẫn lắp đặt công tơ điện tử 1 pha emic CE38
a. Chuẩn bị lắp đặt
. Ngắt nguồn điện tổng trước khi lắp đặt
. Chọn vị trí khô ráo, không ẩm ướt, tránh ánh nắng trực tiếp
b. Sơ đồ đấu nối cơ bản
. L/N vào:kết nối từ nguồn điện lưới
. L/N ra:kết nối tới tải (thiết bị tiêu thụ điện)
Lưu ý:Đảm bảo dây dẫn đúng tiết diện phù hợp với tải, siết chặt đầu nối để tránh đánh lửa hồ quang.
c. Kiểm tra sau lắp
. Cấp điện, màn hình sẽ hiển thị thông số
. Kiểm tra các thông số (V, A, kWh…) có hoạt động ổn định không
. Thử tải để kiểm tra đo lường chính xác
5. Ứng dụng thực tế của công tơ điện tử 1 pha Emic CE38
📍 Nhà trọ, phòng cho thuê: Dễ dàng reset số mỗi tháng để tính điện cho từng phòng.
📍 Hộ gia đình có hệ thống điện mặt trời: Theo dõi lượng điện tiêu thụ chi tiết.
📍 Văn phòng, cơ sở sản xuất nhỏ: Quản lý tiêu thụ điện từng khu vực.
📍 Shop, cửa hàng: Tối ưu hóa chi phí và phân tích sử dụng điện theo giờ/ngày.
