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

Notes
1
True latching OVP is available as an option. Please add the suffix ‘-V’ to the
model number,
e.g. EXA40-24S1V8-VJ.
Additional alphanumeric suffixes
maybe added to indicate minor modifications not affecting the safety
approvals.
2
Gauranteed minimum output voltage range.
3
Latching OVP response time is 1 ms (typical). OVP latch is reset by
toggling remote ON/OFF or by recycling the input voltage.
4
Figures are percentage of minimum input voltage.

Maximum continuous output power.
40 Watts for S05J models
26.4 Watts for S3V3J models
22 Watts for S2V75J models
14.4 Watts for S1V8J models.
8
User must provide recommended fuses in order to comply with safety
approvals.
9
Maximum temperature on components Q100, Q102 and Q103 not to
exceed 120
°
C. See Application Note 101 for details.
10
For continuous operation below 88%, minimum input voltage trimming up
>5% is not recommended on the 24S05J and 48S05J models.
11
The ‘J’ suffix indicates that these parts are Pb-free (RoHS 6/6) compliant.
TSE RoHS 5/6 (non Pb-free) compliant versions may be available on
special request, please contact your local sales representative for details.

NOTICE: Some models do not support all options. Please contact your
local Artesyn representative or use the on-line model number search tool at
http://www.artesyn.com/powergroup/products.htm to find a suitable
alternative.
CAUTION: Hazardous internal voltages and high temperatures.
Ensure that unit is not user accessible.
