PT4501r = 3.3V/5A (16.5W)  
PT4502r = 5.0V/4A  
The PT4500 Excalibur™ power modules  
are a series of isolated DC/DC converters  
housed a new space-saving copper case. The  
series includes a number of standard output  
voltages ranging from as low as 1.2VDC to  
15VDC, each adjustable by up to 10% of  
nominal. The modules are ideal for Telecom,  
Industrial, Computer, and other distributed  
power applications that require input-to-output  
isolation.  
Using multiple modules, system designers  
can implement a complete custom power supply  
solution. The flexibility of full isolation also  
allows the input or output to be configured for  
negative voltage operation.
