POWER EFFICIENCY

Need to run more than one lab per classroom/school without the lights going out?
No problem, with EarthWalk's integrated laptop and battery charging systems you can power as many mobile computer labs as you need. EarthWalk Wireless Mobile Computer Labs are the most efficient solutions available; this means you can use a standard AC outlet and be assured that you will NOT BLOW A FUSE! EarthWalk has developed, engineered, and patented its PowerSmart electrical and battery power technologies to allow EarthWalk products to operate and perform unlike any other solution available. EarthWalk PowerSmart products provide “Single Plug” electrical operation, simultaneous battery charging,
85% energy efficiency, and virtually continuous “ALL DAY” operation.

POWER-PULSE/POWER MANAGEMENT ARCHITECTURE

One Plug Power Management

EarthWalk's proprietary recharging technology allows all the laptops in your
mobile computer lab to be simultaneously charged from a single electrical outlet.
Without this exclusive Power-Pulse/Power Management Architecture, charging
beyond 16 laptops from a single 16AMP outlet is not recommended - and in
most cases, not possible. Considering most laptops draw at least 2-3 AMPs
during the charging process, overloading can occur very easily. Not only can
this prove costly, it may also pose a safety hazard in your school's electrical
system by overloading circuits and potentially causing older wiring to fail.

Laptop Charging Technology
This power management system is designed to ensure that the proper amount
of power is equally distributed to each laptop without overloading the circuit or
overcharging the laptops. All of EarthWalk's Mobile Computer Lab Solutions
can be integrated with our proprietary Power-Pulse/Power Management Architecture™,
which provides enough power for simultaneous recharging of up to 36 laptops, with
36 additional batteries (depending on the lab selected), and all peripherals from
one standard electrical outlet, generator, or via solar power
- at half the cost.
• Entire system operates from a single, standard electrical outlet
• 110 to 240 VAC, 47-63Hz
• 85% efficient conversion / regulation
• Forced convection cooling / Approximately 2900Btu rejected heat
• Automatic reset fuse on each recharge cable
• 14-20VDC Assuring personnel safety
• Current limited to 6AMP insuring equipment safety
• Safety Specification: UL 1012, TUV EN60950, IEC950 & UL1950 Pending
• EMC Specification: CISPR22 (EN55022) Class B, IEC801-1,2,3,4; IEC 555-2 Pending
