Bretford’s Pulse L Mobile Device Management Carts (MDM) support the modern learning environment. This 20 unit laptop/netbook carts feature a small footprint, an advanced power management system, and the industry’s first desktop cord management system. The Power Manager system uses a Round Robin charging cycle that constantly evaluates the demand for power and concentrates on the devices that need it most. The system inherently senses when batteries are nearing a full charge and automatically reduces power as required. The Power Manager not only prevents circuit tripping, but also allows each set of device batteries to cool down between charging cycles, thereby extending their life.Locking slots in the front of the cart position the cords so they can be easily plugged into the device. And the back of the cart features the first removable cord management system. Each cart has two shelves with individual laser-printed numbers for identification on every device slot. They also include full-access doors in the front for the students and a choice of a panel or full-access door in the back for the person operating the cart.A unique locking handlecan be opened using either a re-programmable combination or a key.
