DESCRIPTION
The PSAHC series of AC/DC switching power supplies provides up to 5.5 Watts of output power in a
2.0” x 1.0” x 0.597” encapsulated PCB mountable package. This series consists of single output
models with a universal input range of 90-264VAC (120-370VDC). Some features include low ripple
and noise, -25°C to +70°C operating temperature range, and over power, over voltage, and short
circuit protection. The PSAHC series also has two types of screw terminal mechanical options and an
extended operating temperature option available. All models are RoHS compliant and have UL/cUL,
CB, and CE safety approvals.
