ИСТОЧНИКИ ПИТАНИЯ MEAN WELL NTS-2
300W~450W
DC-AC pure since wave output (THD<3%)
Convection cooled fanless design, high efficiency up to 93%
200% Peak power capability 
Built-in DIP switches to adjust AC output voltage, frequency, and work mode
Multiple intelligent protection functions:
DC input side – reverse polarity, under voltage, over voltage protections
AC output side – short circuit, overload, over temperature protections
