LRS-50 series is a 50w single-output enclosed type power supply with 30mm of low profile design. Adopting the full range 85 ~264vAC input，the entire series provides an output voltage line of 3 .3v，5v，12v，15v ， 24v，36v and 48v. ln addition to the high efficiency up to 90%，the design of metallic mesh case enhances the heat dissipation of LRS-50 that the whole series operates from -30℃ through 70℃ under air convection without a fa .
