Single Phase Energy Meter

The DS1100 Single Phase Energy Meter from DONSUN Technology is an electronic single meter ideal for domestic and light commercial direct connected applications.

Metering Security


The meter offers high security and detects many of the most commonly used tamper techniques. The display has large easy to read characters with information identified by OBIS. Security data can be included as part of the display sequence and read via the communication ports.

Basic Feature


DS1100 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.
DS1100 can be a simple import meter or for import/export, domestic or for net metering in solar system. An opto-isolated pulsing output can be provided as an option. The output is available via the meter auxiliary terminals.


DS1100 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.

Profile Data Storage

300 days of half hour data available when one channel selected, using a programmable integration
period for up to four selectable channels of load profile for any measured quantity.


DS1100 can be configured by the customer to display English characters or OBIS identification codes.

An optional battery can support the display during power outages.

DS1100 supports symmetrical and sequential connection.
