The CUI Inc. PSK-S3-9 is an AC-DC power supply from the PSK-S3 series, designed for reliable power conversion in various applications. This model delivers a single 9Vdc output with a maximum current of 330mA, providing a total power of 3W. It accepts a wide universal input voltage range of 85-264 VAC or 100-370 VDC, making it suitable for global use.
The converter is designed for through-hole mounting and comes in a 26-DIP Module package with 5 leads. It operates within a temperature range of -40°C to 70°C (with derating) and includes essential protections such as over-voltage, over-current, and short-circuit protection. The unit meets safety standards including CB Scheme, EN, IEC, and UL, with conducted and radiated emissions compliant to CISPR 22 Class A and CISPR 32 Class B.
Key electrical specifications include a high efficiency of 75% at 230 Vac input, line regulation of ±0.5%, and load regulation of ±1%. It also features a hold-up time of 10ms at 115 Vac and 60ms at 230 Vac. The PSK-S3-9 is suitable for ITE (Commercial) applications.
