The CUI Inc. PSK-30D-3-T is an internal AC-DC power supply designed for various applications. It delivers a stable 3.3V output with a maximum current of 6A, providing up to 20W of power. The unit operates with a wide AC input voltage range of 85-305 Vac and features a broad operating temperature range from -40°C to +85°C.
This power supply is certified to safety standards including 62368, 61558, and 60335, and meets Class B emissions standards. It includes over-voltage, over-current, and short-circuit protections for reliable operation. The PSK-30D-3-T is designed for chassis mounting, making it suitable for integration into various electronic systems.
Key electrical specifications include an efficiency of 85% at 230 Vac input, line regulation of ±0.5%, and load regulation of ±2% for the 3.3V model. It also offers a high isolation voltage of 4,200 Vac between input and output.
The AC input voltage range is 85-305 Vac. For DC input (3.3/5/9/12/15/24 Vdc output models), the range is 100-430 Vdc. For 48 Vdc output model, 120-430 Vdc.
The converter is enclosed with chassis mount mounting and packaged in a tray.
