Meter

Panel meter, series of products of electromagnet inner construction, are used to install on the display panel of control and distribution systems and large switchgear panel for indicating the electrical data such as AC, DC current, voltage, power factor, power, synchronization, frequency, over voltage and over current and etc. The products meet standard of GB7676-1998.

Digital meter's Structure: Inverter will rectify the measured signal, combined by logic calculation circuit, and then display by LED digital tube, the characters as follows: (1) Voltage and current transformer inside provided to isolate the input signal, this will increase the overloading capacity; (2) direct display, accuracy, clear; (3) Good visibility, (4) small error, low loss; (5) easy to remotely control.

DD862 single and three-phase watt-hour meter is a kind of induction meter, which is applicable to measure the rated frequency 50Hz and power loss in electrified wire netting. All technical targets are completely conformed to National Standard GB/T15283-94 and International Standard IEC 521.

DD238 single phase long life watt-hour meter is a kind of induction type meter which measure active energy and reactive energy electric power consumption in rated frequency 50Hz and single phase AC electricity net. The type single phase watt-hour meter is a new-style induction type meter which is designed and developed on the basis of type DD111 single phase watt-hour meter and absorb domestic and overseas induction meter new techniques and use long life techniques. Its technique performance are completely conform to the stipulated requirement of National Standard GB/T15283-94 and International Standard IEC521.
