CUI's PSK-S3 and PSK-S5 series are a family of compact encapsulated AC/DC power supplies housed in board mount, chassis mount, wire leads, and DIN rail packages. Outputting 3 W or 5 W of continuous power, these single output, encapsulated modules feature 4 kV_AC isolation and a wide operating temperature range from -40°C to +70°C, making them ideal for a range of space-constrained applications.
