φ (change by voltage curve):
With the setting U
3
φ (change by voltage curve), the target cos-phi is determined by
means of a configurable curve. The voltage is measured either at the basic module or at
the multimess 1D4 additional module. The parameters refer to Un (rated voltage). With a
measured input to the basic module of UPh-N = 230 V, the measured voltage is projected
to a rated voltage (Un) of 400 V Ph-Ph.
Cos-phi2 (power recovery) has no function in this mode.
The cos-phi1 (power consumption) is used for the baseline between the adaption ramps.
A hysteresis can be programmed using the “hyst.” parameter.
The transition to the new target cos-phi can be attenuated using the “t-delay” parameter.
New values are adopted once per second.
