DESCRIPTION
The ME series of medical approved (UL/cUL 60601-1) dc/dc converters are specially designed to provide ultra high levels of isolation
(5600VDC) in a 24-pin DIP package. 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.
