The Cosel VAA505 is an open frame AC-DC power supply designed for ITE (Commercial) applications. It delivers a stable 5V DC output at up to 1A, providing a total of 5W maximum wattage. The unit accepts a wide input voltage range of 85 to 132 VAC or 110 to 170 VDC, with a typical efficiency of 75% at full load.
This converter features through-hole mounting and a 5-DIP module package, making it suitable for PCB integration. It includes overcurrent and overvoltage protection circuits for enhanced reliability. The operating temperature range is -10°C to 70°C with derating, and it meets UL60950-1 and C-UL agency approvals.
Key electrical specifications include line regulation of 20mV maximum and load regulation of 40mV maximum. Ripple and noise are kept to 80mVp-p maximum at operating temperatures up to +55°C. Isolation ratings are 2000 VAC for input-output and input-FG, and 500 VAC for output-FG.
