These converters operate over input voltage ranges of 9-18VDC, 18-36VDC, and 36-75VDC. This series also provides regulated single and dual output voltages of 5, 12, ±12, and ±15VDC. The -40°C to +55°C operating temperature makes this series of dc/dc converters ideal for data communication equipment, mobile battery driven equipment, distributed power systems, process/machine control equipment, telecommunications equipment, mixed analog/digital subsystems, computer peripheral systems, and industrial robot systems. These converters have a power rating of 6W and a typical full load efficiency of 80%. This series complies with EN55022 Class A conducted noise and radiated emissions with an external coupling capacitor Cio=1nF < Class B. The EN55022 Class A conducted noise compliance minimizes design time, cost, and eliminates the need for external filter components. All models are over load and short circuit protected. SPECIFICATIONS: ME Series All specifications are based on 25°C, Nominal Input Voltage, and Maximum Output Current unless otherwise noted. We reserve the right to change specifications based on technological advances.
