EXA40-48S05J Datasheet | Emerson

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) - plies with ETS 300 019-1-3/2-3 - plies with ETS 300 132-2 input voltage and current requirements - Fully pliant with ETS 300 386-1 - Ro HS pliant The EXA40 Series, prising 8 different models is targeted specifically at the telemunications, industrial electronics, mobile Telemunications 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 Telemunications applications and plies with ETS 300 386-1 immunity and emission standards for high priority of service class. In addition the series plies 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 2 YEAR WARRANTY SPECIFICATIONS OUTPUT SPECIFICATIONS Voltage adjustability (See Note 10) Voltage accuracy Line regulation Load regulation Minimum load Ripple and noise 20 MHz bandwidth Temperature coefficient Transient response Peak dev. settling time Short circuit protection (See Note 5) INPUT SPECIFICATIONS Input voltage range Input current UVLO turn ON voltage UVLO turn OFF voltage Start-up time 24 Vin nominal 48 Vin nominal No load Remote OFF All inputs (See Note 4) All inputs (See Note 4) Nominal line 18-36 Vdc 36-75 Vdc 100 m A max. 4 m A max. 94% 86% 50 ms...
