DESCRIPTION
Size:
2.06 x 1.07 x 0.93 inches
52.4 x 27.2 x 23.5 mm
The PSAFC20 series of AC/DC switching power supplies provides up to 20 Watts of output power
in a 2.06” x 1.07” x 0.93” 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, -40°C to +70°C operating temperature range, and over power, over voltage,
and short circuit protection. The PSAFC20 series also has two types of screw terminal mechanical
options available. All models are RoHS compliant and have UL/cUL, CB, and CE safety approvals.
Weight:
