DTSY175D (One meter and more cards) electronic pre

Product Overview One meter and more cards prepaid electrical meter is the new generation of electrical meter with IC cards as the medium to specific energy-measurement integrated circuit and pre-paid control chip as the core, formed by the optimized design. It can achieve "first payments, after the power" of the power management mode. The electrical meter can be "one meter and more cards ", pre-payments, automated billing run, can be widely used for irrigation, public power management occasions. Product indicators of the system are better than GB/T17215-2002 and GB/T18460.3-2001 standards. Main functions Intelligent control One meter and more cards, multi-user management Data read-back function Fill cards Data encryption Monitoring Query display Bayonet anti-attack function Main Features Adaptation range, reliability One meter and more cards multi-family, independent, no interference Unique redundancy design techniques, has good anti-jamming performance Unique bayonet attack prevention technology, from vandalism by outsiders Specifications Operating Voltage:AC220V±20%,3*380V±20% Rated voltage:3*10(40)A,3*20(80)A Start current:In the reference voltage, reference frequency and COSφ= 1.0 conditions, the load current is 0.4% Ib (1.0 level) .The electrical meter may continually measure electric energy.
