Overview
Functional Configuration
The K9203 combines three-axis fan cooling with a run monitoring function. It circulates air through the control cabinet to remove heat generated by installed equipment. Meanwhile, the run monitor provides an indication of fan operating status, helping maintenance personnel identify operating conditions.
Electrical and Cooling Performance
The fan drawer operates from a 24 VDC supply. Its maximum current consumption is 750 mA. The specified airflow is 300 m3/h, with a rated fan speed of 2,800 min-1 and an approximate sound pressure level of 55 dB(A).
In addition, the stated service life is 62,500 hours at 40 deg C. The power supply specification includes a voltage tolerance of -15% to +20% and a ripple limit of 15%.
Cabinet Installation and Environmental Conditions
The K9203 uses a 19-inch, 1 RU mounting format with a depth of 215 mm. Its anodized aluminum construction forms the fan drawer housing. The specified ambient operating temperature ranges from -20 deg C to +70 deg C.
