DESCRIPTION
The PSAIC series of AC/DC power supplies provides 3 watts of output power in a 1.41” x 0.75” x
0.86” encapsulated PCB mountable package. This series consists of single output models with a
universal input range of 90-264VAC or 120-370VDC. Some features include low ripple and noise,
-40°C to +85°C operating temperature range, and < 0.3W no load power consumption. All
supplies are over power, over voltage, and short circuit protected. The PSAIC series has two
types of mechanical options available. All models are RoHS compliant and have UL/cUL and CE
safety approvals.
