Applications
The UMG 507Emax is a multifunctional instrument which is essential as basic equipment in low voltage main distribution systems.The maximum effective power is reduced with the peak load manager UMG 507Emax through the quick shutdown of consumers.
Furthermore, the instrument also enables time- or event-related switching of consumers with the integrated weekly time switch.
The UMG 507E is available as a basic instrument with additional components integrated in the steel housing or as individual component. As a measuring instrument, the UMG 507Emax monitors the loads upon the electrical supply systems in order to avoid overload.
The instrument is also designed to measure and store almost all electrical parameters including average current and power values (refer to catalogue page 56 et seq).
Functional principle
The UMG 507Emax determines the necessary parameters for compliance with up to 5 stipulated nominal values in kW based on the effective power pulses entering the digital input or the overall effective power calculated by the instrument. The instrument continuously calculates the average value, actual value, trend value and correction power within the set time period.
If the instrument identifies that the maximum power may be exceeded, it checks whether the consumers have to be switched off using the preset consumer parameters. The aim of this method is to insignificantly impair the operational process with as few switching processes as possible while still complying with the given nominal demand value.
Depending upon the product variant, there are up to 32 shutdown stages available (change over contact is potential free) for the consumers and two optional analogue Emax channels for the control of generators.
UMG 507Emax peak demand management system assembled in a steel housing for wall mounting, wired ready for connection on terminals, includes PSW basic and standard programming.
