ZYSM8118-1 Single-phase Energy Meter

Data processing functions include:

1.1 Energy Metering

1. Energy measurement using digital measuring chips, therefore metering
   precision can be digitally verified.
2. Export energy is counted into import energy register too, i.e. import = Export +
   import. There is another group of energy registers for metering Export energy
   only, this way IPGSM01 can flexibly meter bidirectional energy.
3. 4-Tariffs and total energy metering of active import and export energy.
4. There is one pulse output which can be used for verifying pulse or collected by
   other equipment. The pulse width is 80 ms. Energy pulse will be output upon
   both active import and export energy.
5. Pulse indication of energy metering using one bright LED which indicates
   active energy. (The LED’s on time equals to the output width of verifying
   pulse).

1.2 Measuring of instantaneous data
the following data can be displayed or readout by
optical or electrical interface

1. voltage
2. current
3. active power
4. power factor

1.3 Inputs and outputs

1. Passive pulse output interface with optical-coupling insulation, which meets IEC
   62053-31.
2. User can read and program IPGSM01 through optical port communication at
   baud rate 2400 bps.
