kWh meters feature exceptional accuracy New from Crompton Instruments, part of the Energy Division of , are single- and three-phase kilowatt hour energy meters, which measure real consumption of active energy to an extremely high degree of accuracy.
The DRK-1P-230-D63 Single-Phase and DRK-3P-400-D90 Three-Phase kWh Energy Meters feature the highest Class 1 accuracy in accordance with CEI-EN 62053-21, with ease of wiring, a back-lit LCD, non-zeroing total counter, and partial zeroing counter. Passed vertically through the meters’ housings, the load cable allows direct connection of up to 63A (single phase) or 90A (three phase). |
Requiring no maintenance, the new kilowatt hour energy meters support energy efficiency and awareness, and ensure systems remain balanced and safe. Principal equipment applications include switchgear, distribution systems, generator sets and control panels, while the meters may also be used in energy and building management, utility power monitoring, process control, and secondary metering. Salient features include a nominal input voltage of 230Vac L-N (400VAC L-L), with an opto isolated pulsed output. The meters are compliant with IEC EN62052-11, IEC EN62053-21 (2003-03), EMC and LVD standards.
