The PSK-4-15 is a compact board-mount AC-DC converter manufactured by CUI Inc., designed for applications requiring reliable isolated power conversion. It accepts a universal input voltage range of 85 to 305 Vac (or 120 to 431 Vdc) at 50-60 Hz frequencies. The unit delivers a nominal 15 Vdc output capable of sourcing up to 266mA, yielding a maximum output power of 3.9W. Line regulation is maintained within ±1% and load regulation within ±3% under full load conditions.
Electrical performance includes an efficiency of 81% at 230 Vac input and full load, with ripple and noise limited to 150mVp-p under standard testing conditions. The converter incorporates comprehensive protection mechanisms, including over-voltage protection at 19.5 Vdc, over-current protection triggering at 110% of rated current in hiccup mode, and short-circuit protection with automatic recovery. It maintains a hold-up time of 16 ms at 115 Vac input and draws less than 0.075W in no-load conditions.
Designed for robust operation, the module supports capacitive loads up to 266μF and provides 3000 Vac isolation between input and output for one minute. It operates reliably across a wide temperature range of -40°C to 80°C with derating, and functions at altitudes up to 5,000 meters. The component is housed in a 4-DIP module package measuring 41.1mm x 21.0mm x 20.0mm, intended for through-hole mounting on printed circuit boards. These characteristics make it suitable for industrial control systems, instrumentation, and embedded equipment requiring isolated DC power rails.
The converter accepts an input voltage of 85 to 305 Vac and provides a nominal 15 Vdc output.
It is housed in a 4-DIP module package designed for through-hole mounting.
The unit operates reliably from minus 40 degrees Celsius to plus 80 degrees Celsius with derating applied above fifty degrees.
The converter offers 3000 Vac isolation between the input and output terminals when tested for one minute.
It includes overvoltage protection at 19.5 Vdc, overcurrent protection in hiccup mode, and short circuit protection with automatic recovery.
