The TDK Corporation KPSB6-3R3 is a cost-effective, board mount AC/DC converter from the KPSB series. It offers high efficiency levels up to 75% in a compact footprint.
This converter operates with a wide input voltage range of 90-264 VAC, making it suitable for global applications. It provides a single output of 3.3V with a maximum current of 1.5A, delivering up to 5W of power. Key electrical specifications include a low no-load power consumption of less than 0.075W and a hold-up time of 12ms at 115VAC input.
Designed for flexibility, the KPSB6-3R3 features an open frame construction and through-hole mounting. It operates across a wide temperature range from -40°C to 80°C with derating. The unit is Class II double insulated, allowing operation without an earth ground connection.
Compliance includes EN55032-B for conducted and radiated EMI, and FCC Part 15 Class B. It also meets IEC61000-3-2 Class A for harmonic compliance. Safety certifications include IEC/UL/CSA/EN62368-1, CE Mark, and UKCA Mark, suitable for ITE (Commercial) and Household Appliances applications.
