Ruggedized Design
A ruggedized computer is a computer specifically designed to operate reliably in harsh usage environments and conditions, such as strong vibrations, extreme temperatures and wet or dusty conditions. They are designed from inception for the type of rough use typified by these conditions, not only in the external housing but also in the internal components as well.
In general, ruggedized and hardened computers share the same design robustness and frequently these terms are interchangeable.
Wide Temperature Range
For many embedded applications, particularly those in military transportation, or where systems must be operated in harsh outdoor environments, a wide operating temperature range of -40 °C to +85 °C is typically expected, and this can be a challenging requirement to meet.
Fan – less Design
Usually the processor is the main heat producing part, but chipset and regulator parts also can generate significant amounts of heat. The processor and chipset should therefore be chosen to be as low power as possible, while still providing for the application processing requirements, and be verified to operate over the temperature range required.
The heat removal from the back surface of the die at the top of the processor package is a key part of the design. The heat spreader can also be used to touch most of the other main heat generating components.
Fans contain moving parts and are therefore vulnerable to wear and eventual failure. Although airflow from fans is very effective to remove heat from components, fanless designs are preferred because they have much higher reliability. Fanless systems are possible to achieve by factoring in careful thermal design considerations.
Water – Dust IP Proof
IP stands for International Protection Rating. IP codes classify and rate the degree of protection provided against the intrusion of solid objects, dust, accidental contact, and water in mechanical casing and with electrical enclosures.
Solid particle protection
The first digit indicates the level of protection that the enclosure provides against access to hazardous parts (e.g., electrical conductors, moving parts) and the ingress of solid foreign objects.

Wide Voltage
Wide Voltage could be completed as wide voltage solutions with acceptance of 9V～32V DV power input. The wide voltage design is not only for concerning of high voltage equipment, but also for those worries of different power input.
Particularly for electronic products used in public transportation and automotive, the voltage specification requires 5V~42V.
Anti – Vibration
Different applications have different anti-shock and anti-vibration requirements. Our products have different levels of shock and vibration protection standards. With the choice of different materials such as butyl rubber, ENR, high damping silicone and SBR, and appropriate structural design, they can meet vertical market standards. Proper packaging is also taken into account to prevent damage to the product due to impact and vibration during transportation.
