Our advanced TWICE THE POWER IN HALF THE SP ACE technology yields a very small footprint, reduces wasted power, and offers the highest Typical Mechanical Drawing: power density in its class. This efficient Inches (millimeters), connectors and pinouts may vary with model. design means reduced energy costs, a greater return on your investment, greater Refer to XL275 Product Specification for complete information. reliability and longer product life. .225 5.00 (5.7) (127.0) 4.55 ADVANCED DIGITAL CONTROLLER .225 (115.6) (5.7) 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 XL275 DC - DC 3.00 2.55 Height = 1.5 (38.1) the following parameters: (76.2) (64.8) • DC input voltage • Output voltage • Output current • Transformer temperature • Ambient temperature • Fan tachometer 1.50 The microcontroller enables the main (38.1) 0.75 output whenever all of the required startup (19.1) conditions are met, and shuts it down Screws shown for reference only upon command, loss of input power or whenever excessive loads or temperatures are sensed. ™ PMBus OPTION allows routine remote control of the main ambient and transformer temperatures. TM An optional PMBus digital communications outputs and the 12V fans. It can also notify Because it is programmable, the microcontroller interface is also provided to allow up to four the host if a fan fails (lost tachometer pulses). code can be customized to meet unique XL275 to communicate over the same bus The host can also query the microcontroller OEM requirements. TM using the PMBus protocol. This interface for its output voltage and current plus the Specifications are subject to change without notice. It is responsibility of each customer to thoroughly test each product and part number under their unique parameters and environments to ensure a product will work properly and reliably.
