Description

4 x 3.5" SATA/SAS Hard Drive Trayless Mobile Rack
Next-Generation storage solution
DAT-MRA504 is one of the series products that customized design for industrial-grade, professional-grade storage market. All-metal parts and intelligent temperature control design which provide more rigid quality and greater heat dissipation. With patented NSS connector supports 50,000 times hot swap and Tool-Free design. Suitable for personal professional workstations, industrial computers, machinery and equipment, military and other fields of storage products.
Ultra-rugged and High quality frame
Aluminum outer case, hairline finish, durable and greater heat dissipation. Zinc Alloy door handle can bear over 20KG pull without broken and deformation. SUS430 ejection mechanism, SGCC back cover, Zinc Alloy hook, High-strength heat-resistant fire-rated PC, and aluminum track.
Compatible with thicker and thinner HDD
When the product needs to be used in upright position, thinner HDD might be move around since HDD is in upright position as well. Patent alignment mechanism make sure thinner HDD connected to backplane firmly.
Excellent heat dissipation
Set proper Airflow by vent of front bezel and space between HDDs, plus 80mm fan to enhance heat dissipation, control the HDD surface temperature does not exceed the environmental temperature of 15 degrees, let the HDD works in the normal temperature range any time.
Intelligent temperature control system
When the internal temperature reaches 30 °C, the fan starts running, which extend fan life cycle. Fan speed will be adjusted automatically by the temperature change, fan spins at the highest speed when the temperature reaches 40 °C. (HIGH Mode : Fan spins at the highest speed when the temperature reaches 30 °C)
Dual alarm system: buzzer and LED for the fan failure or internal temperature exceeds the setting maximum temperature.
Individual power switch
Every single HDD corresponds to a power switch button,  press the power switch button for 3 seconds to power on or off.
Power on / off for all bays quickly
One button can power on /off all bays sequentially. Time saving and avoid current increased dramatically.
Memorize function
DAT-MRA504 will memorize previous working status of every HDD if it occurs sudden power failure during use. It will automatically restart and back to previous working status after restoring power. This feature is designed primarily for surveillance, servers and other equipment that required long time uninterrupe work. When the power failure occurs during use, after power restore, there's no need to restart DAT-MRA504 mamualy, it can automatically restart and back to previous working status to achieve unattended intelligent mode.
High Quality PCBA
PCBA is designed by the requirement of high-frequency data transmission. Component and manufacturing process are used according to industry standard. PCB with 2.0mm four layers FR-4.
