M-Max 720 PR7 – Battery Powered Rugged Computer System for Mission-Critical Applications

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.
