Compact AC/DC power supplies range from 6-20W

A new line of low power, encapsulated AC/DC power supplies has been added to CUI’s Power Group's broad power portfolio ranging from 1W to 12kW. Housed in a compact, encapsulated board mount package with industry standard pin-outs, the new PSK series offers models with 6, 10, 15, and 20W of continuous power.

Thanks to their compact footprints measuring as small as 50.8x25.4x16.74mm (2x1x0.659"), these rugged, encapsulated modules are suited for low power ITE, consumer electronics, and industrial control applications where board space limitations and environmental contaminants are a concern.

The PSK‑6B, PSK‑10B, PSK‑15B, and PSK‑20B series all offer 4kVAC isolation, no-load power consumption less than 100mW, and operating temperature ranges at full load from ‑25 to 50°C, derating to 50% load at 70°C. A wide universal input voltage range of 85-264VAC is featured with single output voltages of 5, 9, 12, 15, 24, and 48VDC, depending upon the series.

Carrying UL/cUL and TUV 60950-1 safety certifications while meeting EN 55032 Class B and FCC Class B limits for radiated emissions, all models come standard with short circuit, over current, and over voltage protections. Calculated per MIL‑HDBK‑217F, the 6-20W modules also carry a minimum MTBF of 300,000 hours at 115VAC at 25°C ambient.
