Energy Saving 24 Hour Timer
All EcoCartTM models are fitted with an energy saving programmable 24 hour timer (ECO CART L30H models feature
2 individual timer units). Each timer features 2 timer options allowing you to set your unit to automatically start
charging over 2 separate time periods in one 24 hour period. This could be from 6:30am to 8:30am ready for
morning classes and then again at 12pm to 1pm ready for afternoon classes. The timer can also be set be set to
charge your laptops during the evening or weekend to take advantage of off-peak energy supply hours, helping to
reduce your electricity bills.
All ECO CART L30H models feature 2 individual timer units. Each of these units manages the charging time for 15 of
the laptops charged inside the cabinet. This enables you to set the unit so that all 30 laptops charge at once or you
can set different charging times for each set of 15 laptops. NOTE: Due to the built in power management system on
the EcoCartTM, all 30 laptops can be charged at one time without the risk of tripping your building circuits.
