EXA40 Series
DC-DC CONVERTERS
Single output
40 W High Efficiency DC-DC Converters 1
* 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.
All specifications are typical at nominal input, full load at 25 C unless otherwise stated

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 m. 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.
