●ADVANCED DIGITAL CONTROLLER
■The XL275 is the first power supply in this class to use a dedicated digital microcontroller to supervise the unit’s operation. The microcontroller monitors parameters:
◆DC input voltage
◆Output voltage
◆Output current
◆Transformer temperature
◆Ambient temperature
◆Fan tachome
●The microcontroller enables the main output whenever all of the required startup conditions are met, and shuts it down upon command, loss of input power or whenever excessive loads or temperatures are sensed.
●PMBUS™ OPTION
■An optional PMBus™ digital communications interface is also provided to allow up to four XL275 to communicate over the same bus using the PMBus™ protocol. This interface allows routine remote control of the main outputs and the 12V fans. It can also notify the host if a fan fails (lost tachometer pulses). The host can also query the microcontroller for its output voltage and current plus the ambient and transformer temperatures. Because it is programmable, the microcontroller code can be customized to meet unique OEM requirements.
