PWS240 Series Light Duty AC/DC Power Supplies

PWS240 Series Light Duty AC/DC Power Supplies

BENEFITS

  • Quiet operation
  • Reliable
  • Economical
  • Lightweight

The PWS120 and PWS240 Series of power supplies provide 12Volts DC at more than 120 Watts or 240 Watts of continuous power from a 110 or 220 Volt AC source.

Their new design uses MosFet based Switchmode technology for high reliability, high efficiency and minimum size. Current limiting and safe operating area circuitry protect the transistors.

A crowbar circuit protects any devices powered by the unit from excessive voltage in the unlikely event of a failure.
