1. Overview

The Y951 is a series of smart distribution boxes designed for centralized power supply and remote control across multiple circuits. Supporting 2 to 16 circuits, the series offers various communication options: -G for 4G, -W for WiFi, and -R for RJ45 Ethernet. For example, the Y951-4-G is a 4-circuit 4G smart distribution box.

Built on an industrial-grade architecture, the Y951 integrates remote control, scheduled tasks, status monitoring, and electrical protection. It is ideal for aquaculture, livestock farming, greenhouses, pump/valve control, and environmental monitoring.

Users can remotely monitor device status and control individual circuits via the platform or mobile app. Optional features include current monitoring, power failure/phase loss detection, audible/visual alarms, and integrated displays.

Operating Principle

• The box connects to a 220V/380V AC power source to provide centralized distribution.
• An internal smart control unit communicates with the platform via 4G, WiFi, or Ethernet.
• Users issue start/stop, timing, or linkage commands through the cloud platform.
• Each circuit operates independently and provides real-time status feedback.
• The system supports local automatic linkage, remote manual control, and cloud-based automation.

Application Scenarios

• Centralized power supply for pumps, fans, aerators, and lighting.
• Automated management of agricultural and greenhouse environmental equipment.
• Unattended power distribution for construction sites and remote stations.
• Unified operation and maintenance (O&M) for distributed power facilities.
