The Cosel LEA50F-30-R is an open-frame AC/DC power supply designed for chassis mounting. It delivers a nominal output voltage of 30V at a maximum power of 50W, with an output current of 1.7A. This converter operates with a wide input voltage range of 85-264 VAC or 120-370 VDC, and features efficiencies up to 84% at 200V AC input.
Key electrical specifications include a line regulation of 120mV maximum and a load regulation of 180mV maximum. The ripple and noise are rated at 150mVp-p maximum under typical operating conditions. It offers robust protection features such as overcurrent protection that activates above 105% of rating and overvoltage protection between 4.00-5.25V.
Environmental considerations include an operating temperature range of -10 to +70°C. The unit provides high isolation voltages: 3000 VAC between input and output, 2000 VAC between input and ground, and 500 VAC between output and ground. Its dimensions are 195.0mm in length, 55.0mm in width, and 23.0mm in height.
The input voltage range is 85-264VAC (47-63Hz) and also accepts DC 120-370V.
The nominal output voltage is 30V DC with a current of 1.7A, providing 50W of power.
The operating temperature range is -10°C to +70°C with derating.
The converter is chassis mount in an open frame package with dimensions 195.0mm x 55.0mm x 23.0mm.
It includes overcurrent protection (works above 105% of rating, automatic recovery) and overvoltage protection (115-140% of rating).
Typical efficiency is 82% at 100VAC input and 84% at 200VAC input.
