- Product Introduction
The DTSY Three-phase electronic prepaid watthour meteris a new te of IC card pre-paid meter,which has such function as power metering,load controal and customer information management.It is an ideal product when reforming electric-use system,achieving electrical energy to commercialize,setting charge and adjusting load stage in the electric network.All the indexes comply with the technological specifications aiming to the three-phase electronics pre-paid watt-hour meter in the standard of GB/T 17215-2002 Cl 1 and 2 Static A.C Active Watt-hour Meter and GB/T 15460-2001. This series electronic watt-hour meter has two ways of wiring:Direct wiring or wiring by current transformer.
Used to measure active energy,can normally work over long time without adjustment;
Prepaid by IC card;
Indicative function for phase loss or voltage indication;
One meter one card,with good anti-counterfeit feature;
Low energy alarm;
Overload alarm,auto power shut off due to continuous overload,and recording overload
