CNC YC7VA 2in1 2P Overvoltage and Undervoltage Protector

Key Features

Voltage and Current Display: Real-time monitoring of main voltage and current with a digital display for clear visualization.

Surge Protection: Protects equipment from overvoltage (130-300V) and undervoltage (80-210V) issues.

Customizable Settings: User-configurable voltage values and delay times, stored in non-volatile memory.

High Compatibility: Supports connections using aluminum or copper wires, with a wide operational voltage range (80V-300V).

Electromagnetic Relay Switching: Ensures reliable load switching with durable relay components.

Multiple Protection Modes: Functions include undervoltage, overvoltage, overcurrent protection, and operation as a voltmeter.

Robust Build: Designed to operate under harsh conditions with a wide temperature range (-50°C to 55°C) and high mechanical and electrical life expectancy.
