This instrument measures the load status by inputting the secondary side of the VT and CT, and
displays various measurement values.
In addition, telemonitoring can be done by a variegated output function.

Various Measurement Parameters
■
Element simultaneous display of four measurements by large-scale bar graph and digital three-stage display.
With the combination of bar graph and digital three-stage display, four measurement items can be displayed
at the same time. Main measurements (A, V, W, PF) of the incoming panel can be displayed at the same time.

can be displayed at the same time, also.
■
Higher dimension measurement monitoring function by measurement ASIC of original our company.
Measuring elements are current, voltage, active power, reactive power, apparent power, power factor and
frequency. In addition, it can measure harmonics and count active energy (imported, exported) and reactive
energy (imported lag, imported lead, exported lag, exported lead).
■
Conformity with the CE Marking standards.
This instrument conform with the EMC standard (EN61326-1:2006) and the LVD standard (EN61010-
1:2001).
■
Small & Flexible.
Its dimension is 96
×
96mm of DIN size, the depth is 86mm, smaller than the previous model.
And, it does not need the onerous specification of phase wire system when it is ordered because three phase 3-
wire or the three phase 4-wire can be set in the set up mode.
In addition, because the output option can be installed later, it is possible to hold down initial investment to a
phased system expansion plan.
■
Remote Input/Output Functions.
It can expand the remote input/output functions to the ModBus communication. It can observe the state of five
digital inputs and control two digital outputs with the electric power monitor. And, because the latch function
is provided in the remote digital input and the pulse signal of 30ms or more can be maintained, it is possible
to use it as an input monitor of the OCR alarm of ACB.
■
Test Functions.
It can make sure the check of wiring and the check of monitor program of system with the test functions of
analog outputs, pulse outputs, alarm outputs and reply of communication data if there is no measurement
input at the start-up of the equipment.
