300W, Dual Output, AC/DC Power Supply for Rugged Enviroments
Oil & gas, Industrial, Mining, Utility, Telecom, Transportation applications The MIW 302 Series extends the output power range of Absopulse Electronics’ field-proven MIW series of power supplies. This dual-output unit uses high frequency conversion topology to generate 300W output power. This design consists of two completely independent converter stages to provide 150W on each output. The outputs are floating and can be connected in series to generate high output voltage (100 – 250Vdc) or in parallel to increase the output current. Both outputs are highly regulated and independently adjustable. A built-in redundancy diode allows for the outputs to also be connected in parallel for 1+1 redundancy, or handle high peak load currents.The MIW 302 is filtered on the input and output to meet EN55022 Curve B. It is also designed to meet EN 60950 and corresponding UL and CSA standards. This robust converter is convection and conduction cooled and performs to full specification at temperatures from 0ºC to 50ºC. Options include a Form C output fail alarm, a DC-input range of 105Vdc to 350Vdc, a wide range of output configurations and conformal coating for operation in harsh environments. Highly ruggedized versions are also available. The chassis-mount design features low component count and high efficiency. The use of high quality components and rigorous quality control results in an MTBF exceeding 100,000 hours, with a demonstrated MTBF (based on the MIW series) of one million hours at normal operating temperatures.
