The M-Max 720 PR7 is a high performance battery powered rugged computer system for mission-critical applications. The system is designed to operate in extremely harsh environments and is equipped with: GPS module, 900 MHz Radio modem, 48x Isolated Digital I/O interfaces, four functional LEDs, expanded set of RS-232/485, USB 2.0, VGA and Gigabit Ethernet ports. The computer is based on the ultra-low power 1.46GHz Intel Atom Dual Core E3826 CPU. The system is designed to operate as a standalone computer or together with the M-Max B00 external Rugged Battery unit.

The system is built with a 24/28V DC electrical power system with a wide input voltage range from 12V DC to 30V DC. It is resistant to high voltages, spikes, and surges.

The system’s LiFePO4-batteries based UPS provides 10 hours of backup power and supports an online connection to an external Rugged Battery unit. The system provides a smooth switch from the internal to the external battery and back when the power is not provided. One external battery unit provides additional 10 hours of operation for the system.

MicroMax, as a manufacturer of highly rugged industrial computers, takes a customized approach to each client and can provide even a single system for development and production.
