Power supply
Supplied from Accura 2300
1. If through-hole current exceeds 250A, Accura 2350-3PSC-CT5A-90 using external CT should be used.
2. Indicates CT secondary current input range.
3. Only for 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. Maximum 15 Accura 2350s can be connected to each port[RJ12-1, RJ12-2] of Accura 2300.
6. Packaged with device. Core conductor of 6C telephone line should be minimum 0.128mm
2
[26 AWG].
7. Split-core single-phase single-hole power measuring modules can be used in three-phases by installing one module per
phase [A, B, C] and grouping them. In the case of three-phase three-wire connection, it is possible to measure three-phases
only by installing two modules on phase A and phase C.
8. Split-core single-phase single-hole power measuring module meets current accuracy ± 0.2% RD error and power/energy
accuracy IEC62053-22 Class 0.2S
9. Split-core three[single]-phase power measuring modules can increase the maximum ± 1% error depending on the
penetration position of power cable
