KUI30 Series Features Adjustable Output Voltage

Our KUI30 series of AC-DC power supplies includes a wide range of features. In addition to its adjustable output voltage, it includes 3,000 Vac reinforced insulation, low leakage current and low standby power. Units are housed in a 3.34 x 1.36 x 0.77-inch encapsulated package and include overcurrent, overvoltage and short circuit protection. Terminal block, din rail and pin type options are available. Units meet UL/EN/IEC 60950-1, RoHS and REACH standards.
