Power Supply Features
• Efficient operation from 200 to 260 volts ac (12 amperes typical at full output power).
• Low standby and receive power drain, typically less than 100 watts.
• Generator and inverter friendly with acceptable power line frequency range 40 to
400 Hz.
• Fully regulated current-limited outputs.
• Step-start to limit stress on power supply components.
• Exceptional filtering and RFI suppression eliminates receiver birdies common to
most SMPS.
• Compact lightweight design.
