EXA40 Series

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

• High efficiency topology, 91% typical at 5 V

• Approved to EN60950, UL1950, CSA C22.2 No. 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

• RoHS Compliant

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 Vdc to 36 Vdc and

36 Vdc to 75 Vdc. Typical efficiencies are 91% for the 5 V output, 88% for the 3.3 V, 86%

for the 2.75 V and 84% for the 1.8 V. 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.

2 YEAR WARRANTY

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