12. Accura 2300 provides maximum, minimum, and average statistical information on voltage, current, and power over the aggregation interval.
This allows accurate trend analysis of the quality of voltage, current, and power because it includes information of measurement parameters that fluctuate instantaneously in the interval.
13. If RS-485 option is selected, digital input/output channels are substituted with RS-485 channel. Refer to ordering information.
14. Split-core single-phase single-hole power measuring module, Accura 2350-1PSCSH-800A/630A/400A conforms to IEC62053-22 Class 0.2S.

1. If rating current exceeds 250A, Accura 2350-3P-CT5A-75 using external CT(secondary rating 5A) should be used.
2. Indicates CT secondary current input range.
3. Only for dedicated communication with Accura 2300[or 2350] connected by 6C telephone line.
4. There is no functional difference between types A and B in RJ12A and RJ12B.
5. Accura 2300 can connect up to 15 Accura 2350-3P[1P] power measuring modules per port(RJ12-1, RJ12-2).
When connecting special modules other than 3P[1P] power measuring module, refer to individual manual of special module.
6. Packaged with device. Core conductor of 6C telephone line should be minimum 0.128mm²(26 AWG).
