and connecting the Energy + Clock module, besides:
Parameter CVMk CVMk-4C
Date/Time dd/mm/yy hh:mm:ss TIME TIME
Active energy ( two indep. meters in case of
the CVMk-4C: demanded energy (+) and
generated energy (--) )
kWh (+) kWh (+) and (--)
Reactive energy (inductive), two indep. meters kvarh.L (+) kvarh.L (+) and (--)
Reactive energy (capacitive), two indep. meters kvarh.C (+) kvarh.C (+) and (--)
---------------------------------------------------
The CVMk allows reading up to 30 electrical parameters (52 parameters with the
expansion modules), shown in 3 big numerical displays, where you can see:
(a) Phase-phase or phase-neutral voltage of the three phases
(b) 3 parameters of your choice (see attached table)
(c) 3 parameters of your choice (see attached table)
-------------------------------------------------------------------------------------------
And also the MAXIMUM POWER DEMAND: The power demand is integrated
during a prefixed period.
You can select:
a.- The parameter to be controlled (it can measure active
power kW, apparent power kVA or three phase average
current AIII).
b.- the demand period (1 to 60 min.).
This power demand function works with sliding window : shows the accumulated
demand over the last period from "now".
** With the optional module CVM / RED-MAX it is also possible to select a power
demand function with external synchronism and fixed window.
