Easy to install sub-meters

The multi-phase devices can be supplied with the option of either open-collector pulse outputs or Modbus communications. They are also available for either direct connection to the measured supply or connection using 5A current transformers.

The new sub-meters conform to the requirements of EN 50470-3 (Class B) and IEC 62053-0 (Class 1). All meters feature a seven-digit backlit LCD displaying total energy, power, voltage and current for each phase.  They also feature a kWh pulse indicator and dual tariff recording capability.
