DIRIS A60

Multifunction meters – PMD

Energy monitoring and event analysis – dimensions 96×96 mm

DIRIS A60
Function
  • DIRIS A60 is a panel mounted multifunction meter which incorporates all functions of the DIRIS A40 with the addition of enhanced data logging functions, recording curves for quality events.
Advantages
Easy to use
  • Thanks to its large backlit LCD display and its multiple viewing screens with direct key access, the DIRIS A60 provide clear readings and are easy to use. It directly display a number of multi-measurement and metering values : ± kWh, ± kvarh, kVAh, I, U, V, F, P, Q, S, PF, etc.
Detects wiring errors
  • An integrated test function can be utilised to detect incorrect wiring and to automatically correct CT installation errors.
Compliant with IEC 61557-12
  • IEC 61557-12 is a high-level standard for all PMDs (Performance Monitoring Devices) that are designed to measure and monitor electrical parameters in distribution networks.
  • Compliance with IEC 61557-12 ensures a high level of equipment performance, in terms of metrology, and the mechanical and environmental aspects (EMC, temperature, etc.).
Management softwares
  • Optional Ethernet module with Webserver function: For measurement monitoring, data exploitation and the export of load curves remotely without a specific software (web browser access).
  • Analysis software: For the analysis of events data in  order to improve the reliability of the electrical installation.
  • Easy Confic software: For quick and easy remote device configuration; configuration files can be copied from and sent to the DIRIS A60, or they can be created without communication and sent at a later time. Multiple devices can be configured from a single file, which is especially useful for OEMs and panel builders.
Conformity to standard EN 50160
  • EN 50160 is a standard which defines events relating to the quality of electrical networks. The DIRIS A60 captures voltage events in accordance with this standard.
