KPSB – Cost-effective 5 to 25 W board mount power supplies

TDK-Lambda announces the introduction of the KPSB-6 series of 5 to 6 W and the KPSB-25 series of 20 to 25 W board mount AC-DC power supplies. Certified to the IEC 62368-1 standard for Audio/Video, Information and Communication Technology Equipment, the products have a Class II input requiring no earth ground. The KPSB can operate in ambient temperatures of up to -40 to +80°C. These cost-effective, compact PCB‑mount supplies are ideal for factory automation, communications, instrumentation, building security and industrial control applications.

The KPSB-6 measures 39.5 x 19.4 x 18.3mm (L x W x H) delivering 6W output power (5 W at 3.3 V) and has 3.3, 5, 9, 12, 15 and 24 V output voltages. The KPSB-25 measures 50.8 x 27.94 x 24.9mm (L x W x H) delivering 25 W output power (20 W at 5 V) and has 5, 12, 15, 24, 36 and 48 V output voltages. In addition to the open frame board mount packages, encapsulated or chassis mounted models with plug-in connectors are offered.

The series accepts a wide 90 to 264 Vac input operating range and has efficiencies of up to 87%. The KPSB-6 has an off-load power consumption of less than <75 mW and the KPSB-25 <100 mW. The operating ambient temperature for the 6W models is -40 to +80°C, derating linearly to 50% load from 60 to 80°C. Whereas, the temperature range for the 25 W models is -30 to +70°C, derating linearly to 50% load from 50 to 70°C.

All models are certified to IEC/UL/CSA/EN 62368-1 and carry the CE mark for the Low Voltage, EMC and RoHS Directives. The KPSB also meets IEC/EN 60335-1 (Household Appliances) and IEC/EN 61558-1 (Transformer safety). The input to output isolation is 3 kVac and the touch current less than 250 µA. The series complies with the EN 55032-B (Class B) EMI and EN 55024, EN 61204-3 immunity standards.
