GENERAL INFORMATION
WF-8900MBA Series Main Board Assembly Safety Features
Automatic Cooling Fan
e cooling fan in the WF-8900 Series Power Center is incremental and is controlled by the current
drawn out of the converter to the applied load. e 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. is
protects the unit from excessive heat that may damage sensitive components. e unit will restart
once the temperature inside has dropped.
