Single-circuit metering & monitoring diris_989.psd DIRIS A-40 Multi-function meters The solution for > Industry > Building > Infrastructure > Data center Strong points DIRIS A-40 Configuration with EasyConfig Systems. Function The DIRIS A-40 is a panel-mounted power monitoring device (PMD). It is designed for measuring, monitoring and reporting electrical energy. Advantages Assisted configuration The configuration wizard guides the user in a step by step process to configure the DIRIS A-40. It also detects and corrects configuration errors. This cuts the commissioning time in half and always delivers a reliable result. Smart sensors Three current sensor formats (solid-core TE, split-core TR/iTR and Rogowski coil TF) allow integration of the DIRIS A-40 into new and existing electrical installations. Connected to the Cloud The range comprises IoT ready connected products that enable data to be exported automatically for remote operation without any limit on time, distance and time in storage. Better than revenue grade Compliant with the IEC 61557-12 standard, guaranteeing the quality and accuracy of the Power Meter: • Class 0.2 for the meter alone. • Class 0.5 from 2% to 120% of the rated current (full scale), for the global measurement chain (with TE/iTR/TF current sensors).
