Integrated, intelligent control algorithms calculate the active power trend and compare this with the preset target active power
Accurate intervention in the operating process
Short-term switching off of non-critical loads per user stipulations
If feedback processing is connected, only loads which are using power at the time of the calculation are switched off or integrated in the trend value calculation
Advantage: Avoidance of cost-intensive power peaks and indication of cost saving potentials
Power Analyser UMG 508 as Basic Equipment
The UMG 508 is used as a basic device.
Determination of load conditions of the electrical supply equipment for the avoidance of overloading.
Measurement and storage of all electrical variables including current and power values.
Visualisation of the maximum monitor measured values via the device homepage.
Includes system software GridVis®-Basic
Function Principle – Simple And Precise
On the basis of the incoming active power pulse at a digital input, or the overall effective power (transformer measurement) calculated by the measurement device, the Emax program determines the variables required in order to comply with a predefined kW target value.
Constant calculation of the mean value, momentary value, trend value and correction power within the set measurement period.
Load switching in case of exceeding the maximum.
ViLoad shedding takes place with consideration to the pre-defined priority.
Target: Compliance with the specified kW-maximum at the end of a measuring period with the fewest possible switching instances.
Authorisation of a feedback input (release) for each load of the Emax function (optional)
In order to switch off consumers via expansion modules with digital outputs (FBM 10 R-NC) up to 64 channels are possible
Peak Demand Management of up to 64 Load Shedding Stages Depending on Device Type and Emax Application
Overall configuration and evaluation via the UMG device homepage.
Device parameters can be conveniently adjusted on the homepage.
Extract of parametrisation possibilities:Target value, actual value for mean value calculation, measurement period duration, off-time, pause time, availability.
Depending on the electrical loads the following are adjustable: Load name, priority, connection power, minimum switch-on duration, minimum switch- off duration, maximum switch-off duration and availability as a percentage.
The Following Measurement Variables Are Stored in The Device
Mean effective power value synchronous to the measurement period reset.
Trend value recording.
Measurement period reset with state change.
Evaluation takes place via the system software GridVis®.
