DS1800

Single Phase Din-Rail Smart Prepayment Meter

DS1800 launched by DONSUN Technology provides the new benchmark for Din-Rail split smart prepayment meter. The compact 4-terminal DIN rail meter is made compliant with the latest STS standards, whilst providing the key data needed by the Utility. Supplemented to this is the ability for the meter to operate as a standard prepayment or smart prepayment meter with the addition of modular communication.

Metering Security

DS1800

The meter offers high security and detects many of the most commonly used tamper techniques. Security data can be included as part of the display sequence in CIU and read via the communication ports.

Basic Feature

Configuration

DS1800 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.
DS1800 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.

Security

DS1800 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.

Mechanical

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

STS/CTS Compliance

DS1800 Single Phase STS Keypad Prepaid Energy Meter takes 20-digit STS TOKEN as the recharge medium. It is suitable for domestic consumer scenarios. The consumer recharge the meter in energy unit and the meter deducts energy unit based on consumption. The meter is built without keypad but with Customer Interface Unit (CIU), enabling high anti-tamper features.
