Date：2026-04-17 09:02:24 click：0

BX‑COV067 is a high‑power intelligent three‑phase electronic converter designed for reliable power management in unstable grid environments. Popular across Middle East and Africa, this device provides automatic power source switching, comprehensive voltage protection, and real‑time monitoring for homes, businesses, factories, and public facilities.


Product Overview

Built around a high‑speed, low‑power microprocessor and high‑power magnetic latching relay, BX‑COV067 delivers modular, maintenance‑free performance for continuous operation. It automatically switches between utility, backup power, and generator without manual intervention. The unit provides complete protection against overvoltage, undervoltage, overcurrent, and phase loss, making it ideal for unattended operation in hospitals, hotels, supermarkets, industrial plants, and residential installations.

For inductive loads including refrigerators, air conditioners, water pumps, and motors, we recommend operating at no more than 60% of the rated total power for extended service life.


Key Features

Intelligent Automatic Phase Switching

BX‑COV067 continuously monitors L1, L2, and L3 input phases. When any phase experiences overvoltage, undervoltage, overcurrent, or phase loss, the unit instantly disconnects the faulty phase and switches to a healthy power source. The priority sequence follows L1 > L2 > L3 to ensure stable and continuous power delivery.

Adjustable Over & Under Voltage Protection

The converter supports customizable voltage thresholds to match local grid conditions.
  • Overvoltage protection range: 230V–300V
  • Undervoltage protection range: 140V–210V
    When voltage exceeds safe limits, the device cuts off power immediately to protect connected equipment.

Adjustable Delay Function

Reset and startup delay can be adjusted from 1 to 30 seconds, allowing users to set appropriate reconnection times and avoid rapid switching that may damage compressors and motors.

Overcurrent & Phase Loss Protection

With a 63A current limiting threshold, BX‑COV067 quickly disconnects power when current overloads are detected. It also provides reliable phase loss detection and protection for three‑phase systems.

Real‑Time Visual Monitoring

An intuitive digital display shows real‑time L1, L2, L3 phase voltages and load current. Clear LED indicators show power status and active output phase for at‑a‑glee diagnostics.
