2 PRODUCT DESCRIPTION
The MDC-20 is a maximum demand controller, which controls the power demanded by an
installation (or part of it) based on disconnecting certain dispensable loads before the power
exceeds certain limits. This prevents the consumption of excess power or peaks, which
generally result in high penalties in the electricity bill or unwanted tripping of the current limiters.
It is recommended that non-priority loads are disconnected, so that demand management does
not affect the normal working of the installation.
The MDC-20 has an internal web server from which the user can view in real time the variables
measured and others obtained by calculation, and the status of the unit inputs and outputs with
the possibility of managing them.
In addition to providing data reading/writing via the web, the unit has an XML server, enabling
the user to send GET and PUT type requests.
