QPPX AC Power Transducer

The AC power transducer is designed to measure a wide range of electrical parameters and produce both analog and digital output signals, making it compatible with various instrumentation and control systems. It offers a total of four-channel output and allows users to configure the settings either through the panel keypad or a PC. This flexibility enables users to choose and set up to four different data points from a maximum of 26 electrical parameters for sampling and analog signal output.

The QPPX programmable transducer is equipped with three digital input channels and features RS485-Modbus communication capabilities. Additionally, the product can monitor galvanically isolated digital input signals and can be programmed using customized SCADA software. Through the RS485 connection, users can access any of the measured parameters.
