Specifications
When outer set of PT, CT, check to see the primary side input
power is less than 10000 MW
and the value
calculated by the formula below is within above
input measuring range list.
Input range (W) = Primary side input power (W)
(PT ratio) x (CT ratio)
Rated power factor: LEAD 0.5 to 1 to LAG 0.5
<Optional integrated control signal>
Input point: 1 point
Input signal: contact or voltage
Contact signal
ON signal
OFF signal
below 200‰
over 100k‰
Voltage signal
–1V DC, below 200‰
4.5 to 25V DC
ON signal:
Optional integration start (reset, integration start)
OFF signal: Optional integration stop
(Note) Control of optional integration can also be made
through communication. Control by communication is
once made, only control by communication is once
made, only control by communication is made
thereafter.
Integratad lowcut power: Integrated lowcut power below
lowcut power is not made by integrated power,
optional integrated power and integrated pulse
output. Set integrated lowcut power for input to
this instrument .

Output Specs.
Output point: 1 point (commonly used for analog and
integrated pulse outputs)
<Analog Output>
Function: Conversion of output instantanous power into DC
current.
Output signal (instantanous power) : 4 to 20mA DC
Permissible load resistance: 0 to 750
Ω
Input scaling: Indicates instantanous power range to be
converted. Input scaling can be set by “H” and
“L” levls of analog output on parameter setting
screen. Set “L” and “H” levels within measur-
ing range of this instrument. Also set span
(difference between “L” level and “H” level) so
as it would be more than 50% of rated power. If
not specified when ordering, it would be shipped
“L” level at OW, and “H” level at rated power
(W).
<Integrated pulse output>
Function: Outputs pulse in proportion to integrated power
Output signal: Open collector
Output capacity:
200mA, 30V DC
Integrated pulse unit: Indicates actual kWh corresponding 1
pulse input to this instrument. It can be set
through integrated pulse unit characteristic and
mantissa sections on parameter setting screen.
