i-Credit 500B is a single-phase meter that provides a comprehensive solution for residential and small commercial electricity metering. The meter is extremely versatile and has many features that make it ideal for demand management and tariff metering. Key features include flexible tariff and load profile functions, Quality of Supply (QoS) monitoring, tamper detection and support for high-speed communications for local or remote meter reading.


  • Domestic single-phase premises
  • Small commercial premises
  • Suitable for co-generation metering applications


  • Multiple configurations (up to 12) can be pre-loaded in the meter and executed in the field
  • Minimises stock variants - one type of meter can be deployed in many applications
  • Reduced installation time in existing installations by the use of BAZ fixing footprints
  • Choice of build types and communications options to minimise costs


  • Single-element compact meter
  • Four-quadrant metering
  • Suitable for use as Type 4, 5 or 6 meter
  • 5 TOU energy registers, per channel
  • 4 TOU maximum demand registers, per channel
  • Bidirectional energy registration: import (consumed) and export (generated)
  • User-friendly tariff configurability and intuitive display (LCD)
  • QoS (Quality of Supply) monitoring for voltage and current
  •  Tamper detection for front cover open

The success of the Jemena AMI program can, in part, be attributed to Secure’s early commitment to developing a cost effective compliant AMI meter in a market where no such meter existed. Whilst this journey has been challenging, Secure has supported the program from its inception through development, implementation, testing, supply and ongoing support.
