描述

The PBK-5-12 is an AC-DC power supply module designed to deliver regulated 12 Vdc output with up to 5 W continuous power in an ultra-compact SIP package. It features universal input voltage capability (85–264 Vac or 100–400 Vdc), 3,000 Vac isolation between input and output, and integrated protections including over-current, short-circuit, and over-voltage functions. The module achieves 74% typical efficiency and includes comprehensive safety certifications (UL 60950-1, Class II) with EMC compliance to CISPR22/EN55022 standards. With a maximum output current of 0.42 A, ripple and noise of 120 mVp-p, and operating temperature range of -25°C to +85°C, the PBK-5-12 is well-suited for industrial control systems, telecommunications equipment, and embedded applications requiring compact, isolated DC power.
