PRODUCT OVERVIEW  
The EMH-54/3-Q48N-C module offers 54V output at 3  
amps in a Half Brick footprint DC/DC power converter.  
These compact modules measure 2.4˝ x 2.3˝ x 0.5˝  
(61 x 58.4 x 12.7 mm) with baseplate and offer the  
industry-standard Half-Brick footprint. The product is  
designed to fully comply with RoHS-6 directive.  
The modules offer wide range input voltage of  
18-72V. The EMH topology offers high efficiency up  
to 91.5%, good regulation, low ripple/noise, and a  
fast dynamic load response. The module sup-  
plies up to 162 Watts of power and isolation rated  
at 2250V for basic insulation. EMH models are  
designed for demanding telecom, POE (power over  
Ethernet), datacom, and networking applications.  
EMHs feature input filters, input under voltage,  
output current limiting, short-circuit protection, and  
thermal shutdown.
