Description
The FNP300 Series provides highly-efficient ac-dc power supplies, each with one high current output and an
additional standby output, which can be used in a wide range of applications. Passive current share along with
internal ORing diodes allow the FNP300's to be also used in redundant, hot-swap applications. All models meet
international safety standards and display the CE Mark for the low Voltage Directive.
