The PSALC series of AC/DC switching power supplies provides up to 9 watts of output power in a 1.48” x 1.10”

x 1.08” encapsulated PCB mountable package. This series consists of single and dual output models with a

universal input range of 90-305VAC (120-430VDC). Some features include low ripple and noise, -40°C to +70°C

operating temperature range, and over power, over voltage, and short circuit protection. All models are RoHS

compliant and have UL/cUL and CE safety approvals.
