3 Phase WiFi Voltage Protector&Smart Energy Meter – Professional Solution for Global Power Management
The Future of Industrial Electrical Protection
The 3 Phase WiFi Voltage Protector from Liuyi Electric represents a significant leap forward in electrical distribution technology. Traditionally, protecting a three-phase system required multiple disparate components: a voltmeter, an ammeter, a phase sequence relay, and a separate circuit breaker. Our all-in-one 36mm compact DIN-rail module replaces this entire setup, offering a smarter, more reliable, and more aesthetic solution for modern electrical panels. Whether you are a wholesaler looking for high-demand IoT products or an engineer designing a commercial power system, this device is engineered to meet the highest international standards of safety and efficiency.
Specialized Bidirectional Energy Monitoring for Green Energy
With the global shift towards renewable energy, bidirectional metering has become a critical requirement. Our 3 Phase WiFi Voltage Protector is uniquely designed to support Bidirectional Measurement. It can distinguish between power drawn from the grid and power generated by local Solar PV systems or wind turbines that is fed back into the utility grid. This allows users to monitor their “Net Metering” status directly from the Tuya or Smart Life App, providing a clear picture of energy ROI and system performance. This feature alone makes it a top choice for solar installers and green energy consultancy firms.
Unrivaled 13-in-1 Comprehensive Protection Suite
Standard protection devices often fail to detect subtle but dangerous phase anomalies. Our smart protector offers a massive 13-in-1 protection suite, specifically tuned for the complexities of three-phase 4-wire (3P+N) systems.
Voltage & Current Precision: Adjustable thresholds for over-voltage (120V-300V), under-voltage (80V-210V), and over-current (up to 100A) ensure that your equipment operates within its safe “golden zone.”
Phase Health Monitoring: It actively monitors for Phase Loss (Shortage Phase) and Phase Sequence Error. For industrial motors, a reversed phase sequence can cause catastrophic mechanical failure; our device prevents this by instantly cutting power the moment a sequence error is detected.
Imbalance Protection: It detects voltage and current imbalances between the three phases, a common cause of heat buildup and reduced lifespan in electrical machinery.
Leakage (Residual Current) Protection: Built-in leakage detection (10mA-99mA) adds an essential layer of personnel safety against electric shock.
Premium Visual Interface & Industrial Design
The first thing your clients will notice is the High-Definition Color LCD Screen. Moving away from general, low-resolution monochrome displays, our screen provides a vibrant, high-contrast dashboard. It cycles through real-time data for L1, L2, and L3, showing Voltage, Current, and Active Power simultaneously. The newly designed panel, featuring the striking orange and red button accents on a matte grey industrial-grade casing, ensures that this device looks like a premium component in any high-end distribution box.
Global Control via Tuya
Powered by Tuya APP, this 3 Phase WiFi Voltage Protector offers seamless connectivity.
Remote Management: Switch power on/off or change protection settings from anywhere in the world.
Historical Data Analytics: The app stores months of energy consumption and fault history, allowing you to identify power-hungry appliances or recurring grid issues.
Smart Scenes: Link the protector with other Tuya-compatible devices. For example, “If voltage exceeds 270V, send a notification and turn off the industrial AC unit.”
