The Cosel LEA75F-48-SNY is an enclosed AC/DC power supply designed for ITE (Commercial) applications. It provides a 48V DC output with a maximum power of 75W and a current rating of 1.6A.
This converter operates with a universal input voltage range of 85-264 VAC or 120-370 VDC, featuring a frequency range of 47-63 Hz. It boasts high efficiency, reaching up to 85% at 200V AC input, and includes Power Factor Correction (PFC) for improved performance. The unit is designed for chassis mounting and offers features such as adjustable output voltage and overcurrent protection.
Key electrical specifications include a line regulation of 192mV maximum and a load regulation of 300mV maximum. Ripple and noise are kept within limits, with maximum values of 350mVp-p at 0 to +50 C. The operating temperature range is -10 to +70 C with derating. Isolation is rated at 3000 VAC between input and output, and 2000 VAC between input and ground.
