GENERAL INFORMATION
WF-8900-AD-MBA Series Main Board Assembly Safety Features
AUTOMATIC COOLING FAN
The cooling fan in the WF-8900-AD Series Power Center is incremental and is controlled by the
current drawn out of the converter to the applied load. The on-board microprocessor increases
fan speed as the total load increases and decreases fan speed as the load decreases. Unlike
traditional temperature-controlled fans, the load-controlled fan provides better component
cooling by avoiding temperature spikes which can lead to premature component failure.
OVER-TEMPERATURE PROTECTION
If the internal temperature of the converter exceeds a critical point, it will shut down. This
protects the unit from excessive heat that may damage sensitive components. The unit will
restart once the temperature inside has dropped.
