EXA40 Series Single output DC/DC CONVERTERS 40W High Efficiency DC/DC Converters • High efficiency topology, 91% typical at 5V • Approved to EN60950, UL1950, CSA C22.2 No. 234/950 • Operating ambient temperature of -40°C to +70°C natural convection • Complies with ETS 300 019-1-3/2-3 • Complies with ETS 300 132-2 input voltage and current requirements • Fully compliant with ETS 300 386-1 The EXA40 Series, comprising 8 different models is targeted specifically at the telecommunications, industrial electronics, mobile Telecommunications and distributed power markets. The series offers two wide input voltage ranges of 18-36VDC and 36-75VDC. Typical efficiencies are 91% for the 5V output, 88% for the 3.3V, 86% for the 2.75V and 84% for the 1.8V. The series has been designed primarily for Telecommunications applications and complies with ETS 300 386-1 immunity and emission standards for high priority of service class. In addition the series complies with ETS 300 019-1-3 environmental standards all classes including shock, vibration, humidity and thermal performance. A high level of reliability has been designed into all models through the extensive use of conservative derating criteria.
