New single phase (DRK-1P-230-D63) and three phase (DRK-3P-400-D90) module kilowatt hour energy meters have been launched by Crompton Instruments, part of the Energy Division of Tyco Electronics, measuring real consumption of active energy.
The energy meters feature class 1 accuracy with easy wiring, a back illuminated LCD display, non-zeroing total counter and partial zeroing counter. The load cable is passed vertically through the case/housing allowing up to 63 A direct connection (single phase meter) and 90 A direct connection (three phase meter).
Requiring no maintenance, the new kilowatt hour energy meters support energy efficiency and awareness and ensure systems remain balanced and safe. Main applications of the energy meters are switchgear, distribution systems, generator sets and control panels.
In addition the energy meters can also be used for energy management, building management, utility power monitoring, process control and secondary metering applications.
Technical details of the energy meters include class 1 accuracy in accordance with CEI-EN 62053-21, nominal input voltage of 230VAC L-N (400VAC L-L), with an opto isolated pulsed output. The energy meters are compliant with IEC EN62052-11, IEC EN62053-21 (2003-03), EMC and LVD standards.
