EXA40 Series

S i n g l e o u t p u t

•

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. Remote enable and

overtemperature shutdown are included as standard while true latching OVP is

available as an option.

All specifications are typical at nominal input, full load at 25°C unless otherwise stated
