LPS120 Series

The LPS120 AC-DC power supply series delivers 130 watts with single outputs from 3.3 V to 48 V. Featuring active power factor correction to minimize input harmonic distortion, the LPS120 Series compact 85-264 VAC power supplies are ideal for 1U (1.75-inch) rack installations and other low-profile applications. All models also offer a 12V 1/2A auxiliary output and 5V at 1/2A standby output, as well as overload, over-voltage and thermal protection.
