Cube 400
Standard Features Cube 400
• DIN 96x96 Standard Format • True rms measurement to the 30th harmonic individual harmonics to the 15th • Accuracy better than Class 1 • Isolated Pulse Outputs as standard • RS485 MODBUS® • IP54 Protection Category • Designed & Made in the UK with a 5 year Warranty Cube 400 – a DIN 96x96 panel mounting Electronic Multifunction Meter, with a backlit 3 line display. Easy to install and convenient to use. Equally suitable for both 3 wire and 4 wire 3f unbalanced loads, these Meters have been designed to measure accurately irrespective of the type of load – ideal for a motor or heater, or for a modern electronically controlled load. Safe to Use With fully isolated current inputs, installation safety is assured. This allows the Cube 400 to be directly connected under certain conditions and provides versatility of connection. Installation in conjunction with other instrumentation can be carried out safely without affecting accuracy and CTs can be earthed if required. Easy to Install The Cube 400 is fitted with large Rising Cage terminals – allowing connection to a wide range of cables from 0.25mm2 to 4.0mm2 Easy to Configure Cube 400 Meters are configured from the front panel to suit installations using Current and/or Voltage Transformers, with decimal point and legend being automatically set to provide optimum resolution.
