The CUI Inc. PSK-3D-5 is an internal AC-DC power supply module delivering a 5V output at 3W. It features a wide input voltage range of 85 to 305 Vac and 100 to 430 Vdc, making it versatile for various power applications.
This power supply boasts an efficiency of 76% at 230 Vac and includes essential protections such as over-voltage, over-current, and short-circuit protection. The operating temperature range is -40°C to +85°C with derating.
Designed for through-hole mounting, the PSK-3D-5 comes in a compact 1x1 inch encapsulated package with dimensions of 25.4mm x 25.4mm x 17.6mm. It is certified to safety standards including 62368, 61558, and 60335, and meets Class B emissions standards (CISPR32/EN55032).
Applications include household appliances and ITE (Commercial) equipment. The unit provides a single output and is suitable for designs requiring reliable internal power conversion.
The PSK-3D-5 accepts 85 to 305 Vac or 100 to 430 Vdc input and provides a nominal 5 Vdc output.
It utilizes a 5-DIP module package with four leads designed for through-hole mounting.
The converter operates reliably between -40°C and +85°C with derating applied.
It offers a minimum isolation voltage of 4000 Vac between input and output for one minute.
The unit features over-voltage protection at 15 V, over-current protection at 200%, and continuous short-circuit protection with auto-recovery.
Ripple and noise are limited to a maximum of 100 mV peak-to-peak.
