New single phase (DRK-1P-230-D63) and three phase (DRK-3P-400-D90) module kilowatt hour energy meters from Crompton Instruments, part of the Energy Division of Tyco Electronics, measure real consumption of active energy. The new devices feature highest 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 63A direct connection (single phase meter) and 90A 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 are switchgear, distribution systems, generator sets and control panels. In addition the devices 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 devices are compliant with IEC EN62052-11, IEC EN62053-21 (2003-03), EMC and LVD standards.
