Project Description
I. General Introduction
DTSY1598 Three Phase Prepayment Meter adopts 20-digit STS TOKEN as a means of recharging. It is suitable for commercial and light industrial consumption scenarios. The consumer recharges the meter in unit of energy and the meter deduces the unit of energy according to the consumption. The meter is built with a keypad, allowing active energy measurement and prepayment control.
DTSY1598 offers the option of optical communication conforming to IEC 62056-21. The meter includes a measuring unit, RTC, charge control unit and other auxiliary units.
DTSY1598 Three Phase STS Keypad Prepaid Energy Meter takes electricity as your utility bill. Electricity users buy electricity first, and the meter subtracts the energy balance. When the energy balance is equal to 0 or when the overdraft is authorized by both parties, the meter sends a power-off signal in order to control the automatic cut-off of the load switch.
