DONSUN Single Phase Dual Source Prepayment Energy Meter provides the end customer a seamless energy prepayment experience.The dual-source prepayment meter is built with two sets of tariffs and switches the tariff automatically when the power source is changed.
Facilities such as hospitals, high tech factories, high end office buildings, military installations, airports, communication centers, data centers and traffic control have stringent safety standards and require a dual source of power.It may be a combination of generator and utility power, or even two separate utility power sources.
This is precisely the kind of application that Donsun dual-source prepayment meter capable of measuring dual power sources and deduct the right credit correctly.
DS1000 is a good representative of our Single Phase Dual Source Prepayment Energy Meter Series.

When the Central Control Unit detects the supply source switching, it will send out command to all meters under its management to switch the tariff immediately to match with the current supply.
The dual-source meter contains two sets of tariffs for each supply source, but it will only be recharged in one unified STS token.
The credit will be deducted separately from this total recharged amount.
The energy and credit consumption will be recorded separately into two sets of registers of the dual-source meter, and there is also a total register to record the total consumption and the total recharge amount.
The user can browse through the meter data list to view the credit consumption of each tariff and the corresponding cumulative energy consumed.
