TDK’s 5 to 25W Board Mount Class II Power Supplies Showcase Wide Operating Temperature RangesOctober 10, 2020 by Hailey Stewart
TDK Corporation features the introduction of the KPSB6 series of 5 to 6W and the KPSB25 series of 20 to 25W board mount AC-DC power supplies.
TDK Corporation announces the introduction of the KPSB6 series of 5 to 6W and the KPSB25 series of 20 to 25W 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 (5W at 3.3V) and has 3.3, 5, 9, 12, 15 and 24V output voltages. The KPSB-25 measures 50.8 x 27.94 x 24.9mm (L x W x H) delivering 25W output power (20W at 5V) and has 5, 12, 15, 24, 36 and 48V 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 264Vac input operating range and has efficiencies of up to 87%. The KPSB6 has an off-load power consumption of less than <75mW and the KPSB25 <100mW. 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 25W 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 3,000Vac and the touch current less than 250µA. The series complies with the EN 55032-B (Class B) EMI and EN 55024, EN 61204-3 immunity standards.
