**The Power Signal Conditioner is designed for single-, split-, and three-phase applications, delivering precise measurement and monitoring of key electrical parameters. It measures active (W), reactive (VAr), and apparent (VA) power, along with a full range of instantaneous values including voltage (L-L and L-N), current, frequency, power factor, total harmonic distortion (THD) for voltage and current, and percentage of maximum load. Through Modbus[®] communication, users can also access alarm status and phase angle data, and more, ensuring complete visibility into system performance.** 

Supporting multiple network configurations (single-phase (2-wire), split-phase (3-wire), and three-phase (3- or 4-wire)) the device offers flexibility across a wide range of electrical systems. It features two independent opto-isolated digital outputs and a 4–20mA analog output for seamless integration into control or monitoring systems. With Modbus RTU communication standard and userprogrammable CT and PT ratios, the Power Signal Conditioner can be easily configured to monitor the most critical parameters with high accuracy and adaptability.
