Painel de ventoinhas EFB Elektronik 691655V3

The EFB Elektronik 691655V3 fan panel is a 19-inch, rack-mount cooling unit designed for installation in the roof of networking and server cabinets. The panel is made from steel sheet with a light grey (RAL7035) or jet black (RAL9005) paint finish, has a depth of 352 mm and a width of 48.3 cm, and includes four fans for effective airflow. The unit accepts a rated voltage of 230 V, 50 Hz and features an illuminated ON/OFF switch, rear-sided IEC C14 power inlet and an earth jack. A thermostat and mounting material are included; optional 19" mounting set is available separately.

Advantages

The fan panel offers compact 19" compatibility and a shallow 352 mm depth suitable for standard racks where roof installation is required. Included thermostat and mounting material simplify setup and allow temperature-controlled fan operation. Rear-sided IEC C14 power inlet and separate earth connection keep the power cabling tidy and accessible. The steel construction with industrial paint finish provides mechanical stability and compatibility with common rack colors.

Suitable for

• Cooling networking and server cabinets from the roof
• Applications requiring 19" rack compatibility with limited depth

Recommendations

Install the unit in cabinets with adequate airflow paths and avoid obstructing intake or exhaust areas. Use the thermostat to prevent unnecessary fan runtime and to maintain stable internal cabinet temperatures. Select a power cable rated for the local mains and confirm that cabinet mounting points match the panel depth and 19" mounting pattern.
