DTSD341-5 Three Phase Electronic Prepayment Energy Meter

The three phase 100 Amp IC Card prepayment meter is designed for public prepayment application such as irrigation field.

Key Features:

u  Direct or indirect connection type

u  Measurement of import and export active energy: export active energy will be registered into import active energy

u  Multi-type tariffs: easy to switch between step tariff and TOU tariff are by using IC card

u  Use the logical encrypted card to transfer information bi-directionally.

u  Remaining fee alarm and remaining energy usage day’s alarm, the alarm threshold is programmable.

u  Load management: auto disconnection of over load meter
