Điều khiển chu kỳ tối ưu để điều khiển chính xác cao với độ ồn thấp.
Công ty TNHH Ngân Anh Phát chuyên cung cấp dòng sản phẩm Bộ điều khiển nguồn đa kênh G3ZA OMRON chính hãng xuất xứ Japan tại thị trường Việt Nam.
Kích thước nhỏ gọn hơn so với bộ điều khiển công suất thông thường.
Cho phép điều khiển công suất với độ ồn thấp khi kết hợp với SSR không qua điểm không. (Xem chú thích.)
Một bộ điều khiển có thể kiểm soát đến 8 SSR.
Giao tiếp RS-485 để thiết lập các biến điều khiển và phát hiện cháy hỏng bộ gia nhiệt. Thư viện Smart FB cho G3ZA cũng có thể được sử dụng.
Đạt chứng nhận CE.
