Power Transducer Series L-UNIT

PT TRANSDUCER

(self-powered, RMS sensing)

Functions & Features

• Converting an alternating voltage from a potential

(voltage) transformer into a standard process signal

• Minimum ripple

• No auxiliary power source required

• Isolation up to 2000 V AC

• High-density mounting

Typical Applications

• Centralized monitoring and control of power line and

power supply voltages measured at switch boards

• Monitoring abnormal voltage drops for detecting overload
