The difference between normal hard disk power management, monitoring hard disk power management is more stringent monitoring <br> <br> often need to install multiple hard drives, if there is no good power management, power and security risks will exist. The instantaneous current that the ordinary hard disk starts will reach 2.5 ampere, even higher. The monitoring of the current when the hard disk starts is controlled at 2 amps, you can use a low-power power supply, to avoid the instantaneous high current and burned. In addition, the monitoring hard disk has a power optimization function that can switch to a low-power mode when the hard disk is idle, saving power.
Ordinary hard drive cooling environment is poor, different monitoring environment good hard drive cooling <br> <br> monitor the number of hard disk requirements, but often have few or even a lot of drives, in this context, there is a higher demand for thermal environment. The power consumption of an ordinary hard disk is about 14.5W. If it is a host with a hard disk, it is not a big problem. However, for monitoring such an extreme environment that requires multiple hard disks, the heat dissipation problem caused by this power consumption cannot be ignored. Monitoring hard drive power consumption is very low, 2TB operating power <5W, heat dissipation is naturally low, installing a number of hard drives will not have too high power consumption, to ensure a relatively good cooling environment.
Seek common pursuit of fast hard disk, monitor, hard disk pursuit of lasting stability <br> <br> monitoring of the most important feature is to require a hard disk write long period of time, but not too high demands for data read. This point, the ordinary hard disk from the design can not meet the requirements. Ordinary hard disk is often a random small file to read and write in the home environment, seeking the speed of seeking, and monitoring the hard disk is suitable for continuous large files continue to write, with good stability.
High Precision Optical Glass Window
Windows are optical glass with ground and polished faces that are relatively parallel.They are used to isolate two physical environments while allowing light to pass.Windows made of BK7 material have high transmission in the visible spectral region, do not scratch easily, do not degrade under normal operating environment and hence do not need any special precaution or treatment. Anti-Reflective Coating will provide higher transmission.
China Star Optics offers all types of windows made from different materials. Such as N-BK7, Fused silica, sapphire,CaF2, Silicon, Borofloat, high borosilicate glass and other optical glass supplied by Schott and Chinese CDGM are available upon request.
Windows at shape of round,quadrate, triangular or other polygonal are also available upon request.In addition, we provide a variety of single layer or multiplayer anti-reflecting coating,HR,PR coatings on Optical Windows.
