Isolation 2250V Input-to-  
The 50QBTW12_2.25 converter series is composed of isolated, board-  
mountable, fixed switching frequency dc-dc converters that use synchro-  
nous rectification to achieve extremely high power conversion efficiency.  
These DC-DC converter modules use advanced power processing, control  
and packaging technologies to enhance the performance, flexibility, reli-  
ability and cost effectiveness of mature power components. Each modu-  
le is six-sided metal case enclosed to provide protection from the harsh  
environments seen in many industrial and transportation applications.  
Fixed switching frequency

Note:  
1. Min. load shouldn‘t be less than 5%, otherwise ripple maybe increase  
dramatically. Operation under minimum load will not damage the converter,  
however, they may not meet all specification listed.  
2. All specifications are measured at TA=25°C, humidity<75%, nominal input  
voltage and rated output load unless otherwise specified.  
Negative logic  
• ON  
• OFF  
Short or 0 ~ 1.2 VDC  
Open or 8 ~ 20 VDC  
3. It is recommended to protect the input by fuses or other protection devices.  
4. In this datasheet, all the test methods of indications are based on corporate  
standards.  
5. All characteristics are for listed model, non-standard models may perform  
differently, please contact our technical person for more detail.
