LPQ140 Series

110–145 Watt AC-DC Power Supply

The LPQ140 series of enclosed AC-DC power supplies comprises a single quad output model that provides standard voltages of 5 V, 12 V and -12 V, plus a user-adjustable floating output of 3.3 V to 25 V. The 5 V and -12 V outputs are also user-adjustable and the main 5 V output supports single wire current sharing and remote sense. The power supply accepts a universal input of 85–264 Vac or 120–300 Vdc and has a typical full load efficiency of 75%. It is comprehensively protected against short-circuit, overvoltage and overtemperature conditions. Additional facilities include remote inhibit and remote indication of power failure. The enclosed version of this power supply can deliver 60 watts of output power with free air convection cooling, and 145 watts with 30 CFM of forced air. The top mounted fan version is rated at 100 watts.
