COV029‑D is a high‑power 4‑channel intelligent electronic converter, highly popular in the Middle East and Africa. Specially designed for regions with frequent power outages and large voltage fluctuations, it is widely used in public places such as hospitals, hotels, supermarkets and factories. It realizes automatic multi‑power switching and triple intelligent protection (over‑voltage, under‑voltage, overload), ensuring stable long‑term operation of equipment without manual supervision, making it a reliable guarantee for commercial and industrial power safety.
I. Core Application Scenarios
II. Core Product Advantages
1. 4‑Channel Intelligent Switching with Automatic Priority
2. Full‑Scenario Voltage Protection for Enhanced Safety
- Under‑voltage protection: Automatically cuts off at 120VAC
- Over‑voltage protection: Quickly cuts off at 280VAC
-
Overload protection: 60A for L1/L2, 35A for L3/L4
Fast tripping during abnormal voltage; 7‑second delay automatic reconnection when normal. Resists high‑voltage surges and prevents equipment damage.
