converter modules featuring ultra wide 4:1 input  
voltage ranges in DIP-24 package with  
industry-standard footprint. Input voltages up to  
160 VDC,excellent EMC characteristics and EN  
50155 approval make this product the best  
choice for many demanding applications in  
railroad and transportation systems. Further  
standard features include remote On/Off, over  
voltage protection, under voltage lockout and  
short circuit protection. Typical applications for  
these converters are also in wireless networks,  
telecom/data-com, industry control systems  
and measurement equipments.
