The CUI Inc. PSK-20B-S12 is a compact, encapsulated AC-DC power supply designed for board mounting. It provides a single 12VDC output with a maximum current of 1.6A and a continuous power rating of 20W. The unit accepts a universal input voltage range of 85-264 VAC or 120-370 VDC, making it suitable for global applications.
Key electrical specifications include an efficiency of up to 85.77%, line regulation of ±0.5%, and load regulation of ±1%. The power supply incorporates essential protections such as over-voltage, over-current, and short-circuit protection with auto-recovery. It also features 4000 Vac isolation between input and output.
Designed for through-hole mounting, the PSK-20B-S12 comes in a 4-DIP module package. Its operating temperature range is -25°C to 70°C with derating. The power supply meets various safety and EMC standards, including IEC62368-1, UL62368-1, EN 55032 Class B, and FCC Part 15 Class B, making it suitable for ITE (Commercial) applications.
The input voltage range is 85-264 VAC or 120-370 VDC.
The output is 12 Vdc at up to 1.6 A.
The maximum output power is 19.2 W.
The operating temperature range is -25°C to 70°C with derating.
It uses a 4-DIP Module with through-hole mounting.
It is approved to IEC/UL 62368-1 and 60950-1, Class II.
Over voltage protection (latch mode), over current protection (110% min), and short circuit protection (hiccup, auto recovery).
