PSK-15W-5

The PSK-15W-5 is a compact AC/DC power converter manufactured by CUI Inc., engineered for direct board mounting in industrial and commercial systems. It accepts a universal input voltage range of 85 to 305 VAC at 47 to 63 Hz, making it suitable for global deployment without regional transformer adjustments.

Electrically, the unit delivers a stable 5 VDC output capable of sourcing up to 2.8A, yielding a total output power of 14W. The converter achieves 76% efficiency while maintaining ripple and noise below 50mVp-p. Line regulation is rated at ±0.5%, load regulation at ±1.0%, and output voltage accuracy at ±2% across the full load range. A temperature coefficient of ±0.02%/°C ensures minimal drift under thermal variation.

Protection and reliability are addressed through integrated overvoltage, overcurrent, and short-circuit safeguards. The overvoltage protection triggers at a minimum of 7.5Vdc for 3.3V and 5V models, while overcurrent protection engages at 150% of rated current with self-recovery capabilities. Short-circuit handling utilizes hiccup mode that transitions to continuous operation with automatic restart. Input-to-output isolation is rated at 4000 Vac, and hold-up times reach 40ms at 230 Vac input.

Mechanically, the converter measures 62.0mm in length, 45.0mm in width, and 22.5mm in height, fitting standard low-profile board layouts. It operates reliably within an extended temperature range of -40°C to 85°C with derating applied at higher temperatures. For capacitive loads on the 5Vdc model, the maximum allowable capacitance is 16000µF.
