Series Headline Isolated, 54Vout, 3A, Ethernet Power Half-Brick DC/DC Converters
Series Description 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 effi ciency up to 91.5%, good regulation, low ripple/noise, and a fast dynamic load response. The module supplies 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 fi lters, input under voltage, output current limiting, short-circuit protection, and thermal shutdown.
