OEM is in your options.We can make as your drawings,samples or designs on. estic and abroad. The meter completely accords with relevant technical requirements of class 2 three phase active energy meter stipulated in International stan ard IEC 62053-11. It can accurately and directly measure 50Hz or 60Hz active energy consumption from three phase four wire AC electricity. The CHINT DT862-4 Three-Phase Four-Wire Active Power Meter is designed to deliver accurate and reliable measurements of active power consumption in three-phase electrical systems. With a voltage rating of 220/380V and a current range of 1. As standard products, they are to meter AC active watt-hours Energy of three-phase & four-wire and three-phase & three-wire, whose technology index complies with the standard. Three-phase watt-hour meter is that of inductance type, used for measuring three-phase AC active or reactiv eenergy of reference frequency 50Hz or 60Hz, DT862, DT864, DS862 and DS864 series are the three-phase active energy watt-hour meters,and DX862,DX864, DX865 and DX863 series are threephase.
