Reduce power peaks intelligently

• Constant logging of all electrical parameters• 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 indicationof cost saving potentials

Power analyser UMG 508 as basic equipment

• The UMG 508 is used as a basic device • Features of the UMG 508: - Multifunction 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 - Detailed information regarding the UMG 508 in chapter 02

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 predefi ned 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• Load shedding takes place with consideration to the pre-defi ned priority • Target: Compliance with the specifi ed 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 confi guration 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®
