The PV19A flat-panel computing device is a fully functional computer of a monoblock design, with a 19" screen. The product can be provided with the Akkord or Schit systems for data protection against unauthorized access. Structurally, the device is designed as a protected system enclosed in an aluminum alloy casing. This design allows the product to be operated under severe conditions: in premises, in car bodies of wheel-based and track-based vehicles, at fixed and mobile onshore and offshore facilities. The flat-panel computing device can be installed on fixed or vibrounloaded supports or on RVR-like vibrounloaded frames, or can be integrated into a standard 19" rack, a control panel or other consumer's equipment.
