The Secure PT1 XX1-121 is a high-precision single-phase AC voltage transducer designed for accurate voltage measurement and signal conversion in industrial power monitoring applications. Featuring Accuracy Class 0.2, the transducer provides highly reliable True RMS measurements and converts the measured AC voltage into two galvanically isolated analog outputs for monitoring, automation, and control systems. Its compact DIN rail-mounted design, configurable output options, and fast response time make it ideal for switchgear, control panels, substations, OEM equipment, and energy management systems.
