M-Max 820 EP/USO

Rugged Industrial Error-free Rackmount System
  • Details
  • Specification
  • Intel Core i7 CPU based
  • ‘2 out of 2’ or redundant architectures
  • IP65 rated
  • Operating temperature<br>from -40 to +55 °C

M-Max 820 EP/USO consists of two rugged industrial computers with the highest performance currently available for systems with passive cooling. It is designed to provide reliable operation using ‘2 out of 2’ or redundant architectures in harsh environments for critical applications. The fully-ruggedized rackmount aluminum chassis is fanless and utilizes natural convection and conduction cooling in accordance with MIL-STD-810 standards.

Providing shock and vibration protection, the M-Max 820 EP/USO can operate under extreme temperatures (-40 to +55 °C), dust and humidity. Delivering excellent performance due to Intel Core i7 CPUs (2.1-3.0 GHz), it also features excellent 2D and 3D graphics capabilities via VGA interface. Data storage options include vibration proof industrial SSDs with RAID functionality. The computer is used as a part of a safety system at railroad and operate as an optical time-domain reflectometer.

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