LES25A48-1V2REKJ Datasheet | Emerson

features an input voltage range of 18 Vdc to 36 Vdc and 36 Vdc to 75 Vdc and is available with output voltages of 1.2 V, 1.5 V 1.8 V, 2.5 V, 3.3 V and 5.0 V. The output voltage is adjustable from 80% to 110% of the nominal value. The series also has a remote ON/OFF capability. Overcurrent, overvoltage and overtemperature protection features are included as standard. Full international safety approval including EN60950-1 VDE and UL/c UL60950, reduces pliance costs and time to market. All specifications are typical at nominal input, full load at 25 °C ambient unless otherwise stated Patent No. 6,765,810 Other Patents Pending 2 YEAR WARRANTY SPECIFICATIONS OUTPUT SPECIFICATIONS Voltage adjustability Minimum load Overshoot Undershoot Transient response (See Note 1) INPUT SPECIFICATIONS Input voltage range Input current 24 V nominal 48 V nominal No load Remote OFF 18-36 Vdc 36-75 Vdc 50 m A 5 m A Open collector ref to -input Open circuit or >2.4 Vdc <0.4 Vdc up down up down 17.5 16.5 35.5 33.5 V (typ.)
