General description
The N2EFSW3 12W family of switch mode
power supplies delivers typically 12W
output and features wide-range input
(90-264V), small size and light weight.
The units are available only in EU housing.
Output voltage is fixed with a tolerance of ±3% on
PCB. Output voltages are available between 5V
and 24V DC. Secondary plug is available in
different forms. The power supply is for indoor use
only.
