Product Summary
The pkc4131pi 15–18 watts PKC DC/DC power module is especially designed for decentralized –48 and –60 Vdc systems with distributed on-board DC/DC converters. By using thickfilm tech-nology, which provides a high degree of integration as well as efficient thermal management, and by utilizing a 300 kHz switching frequency based on proprietary drive & control circuits, the pkc4131pi can be used in demanding Information Technology and Telecom (IT&T) applica-tions e.g. computers, cellular radio, and telecom switching.
Parametrics
pkc4131pi absolute maximum ratings: (1)Case temperature: –45 to +115 °C; (2)Transient input energy: 0.6 Ws; (3)Storage temperature: –55 to +125 °C; (4)Input voltage: –0.5 to 72 V dc; (5)Remote control voltage pin 1: 0 to 5 V dc; (6)Input to output isolation: 500 V dc.
Features
pkc4131pi features: (1)Regulated single, dual and triple outputs; (2)Low profile 10.7 mm (0.42 in.), allows 0.8 in. board pitch – 0.6 in. if recessed in the printed board; (3)Proven MTBF >2,000,000 hours at +75 °C case temperature and a rugged mechanical construction; (4)Efficiency 85% typ, at full load. No extra heatsink up to +85°C ambient. Max. +115°C case; (5)Low EMI in conformance with class A in EN 55022 and FCC part 15J.
