Theory of operation
Power Management
Solar energy is the standard power source for IPS Multi Space Parking Meters. Electrical energy is derived from high
efficiency solar panels. This input energy is converted by the MSCM to levels suitable charging and maintaining an
external 12V valve regulated lead acid (VRLA or sealed) battery system which in turn supplies power for internal power
backup, internal circuits and external peripherals.
Long term power autonomy is achieved by switching systems off when not in use and by storing surplus energy in a high
capacity VRLA battery. An average of one hour of sunshine per day is required to maintain this autonomy. This may vary
as the requirements for its lighting systems, connectivity and usage change.
The MSCM provides an additional input for a nominal 12VDC input, normally derived from AC mains or other power
systems, to support systems where sufficient solar energy is not available or internal heating elements need to be
powered during very cold conditions.
Idle Mode
A number of configurable idle screens are displayed during idle mode to reassure and inform the potential user of the
operational status of the unit, parking tariffs etc. Other systems, as defined by the configuration of the particular system,
remain inactive to conserve energy. Events such an a person approaching the unit, pressing a key, inserting a coin or
card or bank note will switch the unit to the active mode. The unit may also link up with the IPS managements systems
during this mode if triggered by an alarm condition or to exchange data, configurations or software or to log any
outstanding transaction details.
