The Rail 310V is a DIN-rail mounting triple single-phase multifunction meter with pulse outputs with an accuracy better than Class 1.  Its display shows kWh, kW, V, A for each circuit. It is specifically designed for retro-fit applications and uses a special voltage-output current transducer that can be clipped round the live conductor without producing hazardous voltages on the secondary (as is the case with conventional CTs).

The Northern Design RTU is an extremely cost-effective solution to read meters using Modbus. A DIN-rail meter, three phase, CT connected. It includes 2 isolated pulse outputs, so these are a simple way to interface with other equipment. One can read a wide range of parameters via Modbus. Energy values are kWh, kvarh inductive, kvarh capacitive. Instant values, kW, kVA, kvarh, PF, Hz, Per phase V, A, kW, V per phase, Neutral current, THD for V & I per phase.

The Cube 300 is a very low cost panel-mount 3-phase kWh and kW meter with a pulse output and accuracy better than Class 1.  Its 'Right First Time' installation aids (kW display, CT, VT and Pulse value displays) clearly show if the meter is correctly wired and programmed.

The Cube 300 is a very low cost panel-mount 3-phase kWh and kW meter with a pulse output and accuracy better than Class 1.  Its 'Right First Time' installation aids (kW display, CT, VT and Pulse value displays) clearly show if the meter is correctly wired and programmed.  This meter has Modbus communications.

The Cube 350 is a very low cost panel-mount 3-phase multifunction meter with a pulse output and accuracy better than Class 1.  Its 'Right First Time' installation aids clearly show if the meter is correctly wired and programmed.  Its display shows kWh, kVARh, kW, V, A, PF & Hz.  Other parameters are available via Modbus.

The CubeIP variant of the Cube400 meter allows all parameters to be accessed via an Ethernet network. The meter can be viewed using any Web browser to display the measured parameters.  Parameters may also be read remotely using the industry-standard Modbus TCP protocol. Consumption data is logged at regular intervals and can be automatically exported to a central PC using the FTP protocol. This variant of the CubeIP also has two digital outputs and three digital inputs.

This System Meter variant only shows the basic measurements on the Web interface.

The Cube 400 is a very low cost panel-mount 3-phase multifunction meter with dual pulse outputs and accuracy better than Class 1.  Its 'Right First Time' installation aids clearly show if the meter is correctly wired and programmed.  Its display shows kWh, kVARh, kVAh, kW, kVAR, kVA, V, A, PF, Hz, peak values & demand values.

The Cube 400 is a very low cost panel-mount 3-phase multifunction meter with RS485 Modbus Communications and accuracy better than Class 1. Its 'Right First Time' installation aids clearly show if the meter is correctly wired and programmed.  Its display shows kWh, kVARh, kVAh, kW, kVAR, kVA, V, A, PF, Hz, peak values & demand.  Other parameters are available via Modbus.
