● Complies with EN55022 Class A with External Coupling Capacitor Cio=1nF < Class B  
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.  
We reserve the right to change specifications based on technological advances.
