4.2 Measured circuit
・It is possible to use two different measurement voltages (2 circuits of same system with 1 unit).
・Each unit (main unit, expansion unit (power measurement, power measurement + pulse output)) can
measure 2 circuits of a single-phase two-wire system, and 1 circuit of a single-phase three-wire system
or three-phase three-wire system. Each unit can be used with a different phase and wire system.
However, check the wiring carefully.
・It is not possible to take measurement with only the expansion unit. Every expansion unit must be
connected to a main unit.
Up to 3 expansion units can be connected to 1 main unit.
*Power source system
・The power source system is the electrical power system from one power source (normally one
transformer).
･KW2M-A can measure 1-system max. 24-circuit of 1P2W system and 1-system max. 8-circuit of 1P3W
and 3P3W system by connecting a main unit and expansion units.
・In order to measure several systems, it is necessary to use one main unit for each system.
