PR300 Power and Energy Meter

Product catalog summary

Overview: The PR300 Power and Energy Meter by Yokogawa is designed for universal application across various phase and wire systems, including single-phase and three-phase configurations. It is a panel-mounted device aimed at power facilities and energy consumption monitoring.

Specifications: The PR300 supports universal voltage inputs of 150 V, 300 V, and 600 V with current inputs of 1 A or 5 A AC. It features a digital input, optional analog and pulse outputs, and supports RS-485 and Ethernet communication. The device operates on a power supply of 100-240 V AC or 130-300 V DC.

Measurement Functions: The PR300 integrates multiple measurement functions, including reactive power, apparent power, demand current, and demand power. It also includes a transducer function for 4-20 mA DC output and an integrated pulse output for electric energy.

Display and User Interface: The device features a large LED display capable of showing three measurement items simultaneously. Users can select display items using the SET/ENT key, allowing for flexible monitoring.

Communication and Networking: The PR300 supports RS-485 communication with Modbus/PC link and Ethernet communication, enabling integration with other devices and network-based monitoring. The Ethernet-serial gateway function facilitates connection with RS-485 devices.

Design and Installation: The PR300 is adaptable to various panel sizes and shapes, including DIN96 square and ANSI 4-inch round forms. It supports on-site configuration changes for phase and wire systems, including CT/VT ratios.

Accuracy and Power Consumption: The device offers high accuracy with voltage and current measurements at 0.25% of full scale and active power at 0.5%. It consumes a maximum of 10 VA for AC drive and 5 W for DC drive.

Applications: The PR300 is suitable for general power monitoring, energy consumption tracking, and integration with control devices via network instrumentation. It supports data logging and monitoring through browser-assisted interfaces and FTP functions.
