TDK-Lambda LS75-12 Single Output, General Purpose Power Supply
The TDK-Lambda LS75-12 is a single-output general-purpose power supply. The model converts a universal AC input into a regulated 12 VDC output. This unit delivers a maximum continuous output current of up to 6 A. The model suits industrial automation systems requiring stable, regulated DC power.
The LS75-12 achieves a typical efficiency rating of 84 percent at full load. Its temperature coefficient remains below 0.02 percent per degree Celsius during operation. It operates without requiring any minimum load connection. The remote sense functionality is not available on the model.
The LS75-12 power supply accepts a universal AC input voltage range from 88 to 264 Vac. Its nominal input voltage range is rated between 100 Vac and 240 Vac for operation. The input frequency support for the model ranges from 47 Hz to 63 Hz across conditions. The inrush current for the model at 230 Vac cold start reaches up to 40 A. The model weighs approximately 410 g and is housed in a metal enclosure. The physical dimensions of the power supply measure 129 by 98 by 38 millimeters.
The general-purpose power supply provides an adjustable output voltage range from 10.8 V to 13.2 V for tuning. The load regulation for the model is rated at a maximum value of 96 mV. The line regulation remains within 48 mV across the input range. The output ripple and noise for the power supply stay below 120 mV under load.
The LS75-12 power supply features overcurrent protection that activates above 110 percent with auto recovery. The overvoltage protection on the 12 V output of the model triggers between 13.8 V and 16.2 V. A green LED indicator confirms that the DC output is functioning correctly. The parallel operation of multiple LS75-12 units is not supported by this design. The model operates within an ambient temperature range of -25 °C to 70 °C at start-up. The output power derates linearly to 50 percent between 50°C and 70°C. The humidity tolerance for the model covers 20 to 90 percent RH operating.
