The PSK-25W-24 is a board-mount AC-DC converter from CUI Inc. It delivers a nominal 24 VDC output at up to 1.1 A, with maximum output power rated at 26.4 W. The converter accepts a wide input voltage range of 85-305 VAC and also supports 100-430 VDC input. Input frequency range is 47-63 Hz.
Electrical specifications include typical efficiency of 85%, output voltage accuracy of ±2%, line regulation of ±0.5%, and load regulation of ±1.0%. Ripple and noise is limited to 100 mVp-p. Switching frequency is 65 kHz. Hold-up time is 10 ms at 115 VAC and 60 ms at 230 VAC. The module provides over voltage protection, over current protection, and short circuit protection with hiccup, continuous, auto recovery behavior. Isolation voltage is 4000 VAC from input to output and 2500 VAC from input to earth.
The converter is designed for through-hole mounting and measures 70.0 mm x 48.0 mm x 23.5 mm. It operates over -40°C to 85°C with derating. Safety approvals include IEC 62368/EN 62368/UL 62368, and it is rated Class II. EMI/EMC compliance is to CISPR32/EN 55032: 2015 Class B. The part is intended for ITE (commercial) applications.
