Single Phase Prepayment Meter

The successful range of DS1000 meters from DONSUN Technology provides a cost-effective solution for prepaid metering solutions. Only complete availability of reliable metering data guarantees an efficient billing process. DS1000 is built as per the well-established DLMSTM to comply with the IEC62056 standard. An optimal data flow is archived through the communication optical port.



DS1000 measures reactive energy in addition to active energy and is ideally suited for utilities who wish to bill or monitor energy consumption based on kvarh measurement. The meter offers additional instrumentation values and maximum demand as well.

Basic Feature


Meter are compliant to IEC 62055-31, having an ingress protection of IP54 to IEC 60529 and comply with EMC standard IEC 50081-1.


DS1000 offers high security with various useful security features. The meter stores all registration and configuration data to nonvolatile memory. All data is retained for the life of the meter. Recordable security features are provided.

Advanced Feature

IEC 62056-21 optical communications and serial communications

Maximum demand, Voltage and current instrumentation values registration


DS1000 can be configured by the customer to display English characters or OBIS identification codes.

An optional battery can support the display during power outages.
