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.
5 Rshort ≤20 mΩ.
6 TVS spec : 6V8 @ 10 mA, 10V5 @ 57 A
4V1 @ 1 mA, 7V3 @ 50 A
7 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.
12 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.
