CIRCUTOR MK-363-B Series - Manual (Page 4)

-- MKB-363-M ELECTRONIC METERS -- M-981198 -- Page Nº 4
Basic Features:
- Active energy computation algorithm uses Aron connection
principle, so phases L1 and L3 include current transformers
and L2 is the voltage reference phase. This allows to use this
active energy meter in any three-phase three-wire system
without neutral or earth currents.
- All energy meters operate over two quadrants: consumed
power.
- Current transformer (only phases L1 and L3):
nominal current : 63 A
maximum current : 90 A
- Electrical accurancy :
Class 2
- All energy meters have two pulse outputs: one for the kW·h
consumed and the other with a timer. The energy output
permits a remote transmission of the measurement of the
kW·h consumed to a PLC or an energy meter centralisation
unit like CIRCUTOR LM24. The timer output allows to
compute the average active power for 15’ periods.
