San Jose, CA — NK Technologies proudly announces the introduction of the VT3-OS Series AC Voltage Transducer, engineered to deliver accurate, reliable voltage monitoring for three-phase applications across industrial and commercial systems.

Designed and assembled in the USA, the VT3-OS Series expands NK Technologies’ voltage sensing portfolio with a robust transducer that delivers True RMS voltage measurement, flexible mounting options, and integral fault detection features suitable for challenging electrical environments.

Key Features & Benefits:

• Precise Three-Phase Voltage Monitoring – The VT3-OS Series accurately senses three-phase voltages in common ranges (120, 240, and 480 VAC) up to 600 VAC, enabling dependable measurement in industrial systems and automation environments.
• Phase Loss Detection – Built-in phase loss detection with an SPST Form A relay output provides enhanced system protection by alerting operators to voltage drop or loss conditions that could impact equipment performance.
• Versatile Configuration Options – Available in both 3-wire (Line-Line) and 4-wire (Line-Neutral) configurations, the VT3-OS supports common power distribution architectures while delivering industry-standard analog outputs proportional to the measured voltage.
• Flexible Mounting & Powering – With both DIN rail and panel mount housings, the VT3-OS fits easily into control panels and electrical cabinets. It is externally powered by 24 VAC/VDC, providing low power consumption and installation flexibility.
• Industry-Standard Outputs – Outputs such as 4-20 mA, 0-5 VDC, and 0-10 VDC ensure seamless integration with PLCs, SCADA systems, and other automation and control systems.
• Global Certifications – UL/cUL listing and CE certification ensure the VT3-OS Series meets international safety and performance standards for use worldwide.
