About This

【Intelligent Three-Way Power Automation】 Effortlessly manages power sources by automatically switching loads between your Main supply and two backup options (like generator and inverter) during outages or instability. Ensures continuous operation by prioritizing a return to your preferred power source once it's restored and stable.
【Fully Adjustable Voltage & Current Protection】Provides comprehensive electrical safety with overcurrent protection (up to 63A) and fully customizable voltage thresholds. Precisely set undervoltage (80-220V) and overvoltage (110V-300V) trip points to match your equipment requirements and grid conditions.
【Tri-Source Voltage Monitoring at a Glance】 Features three dedicated LCD screens that provide simultaneous, real-time voltage readouts for all three independent power sources (L1, L2, L3). Instantly assess the status of each input at a glance, ensuring full situational awareness during critical power transfer events.
【Customizable Transfer & Recovery Delays】 Gain precise control over switching operations with fully adjustable timing. Set the power-on delay (default 5S, adjustable 1-600S) to safeguard generators and the recovery delay (default 30S, adjustable 1-600S) to ensure source stability before re-transfer, preventing short-cycling and protecting your equipment.
【Effortless, Space-Efficient Installation】Engineered for simplicity and durability, this compact unit installs in minutes on a standard DIN rail.
