Power Supply and Power Requirements
ALS-600PS
Power Supply Features
Normal operating range is from 100 volts up to 130 volts 50/60Hz (12-amperes
typical full carrier power) or between 200 and 250 volts, 50/60Hz (6 amperes
typical at full carrier power).
A unique "buck-boost" winding allows compensation for up to six different power
line voltages centered on 115 and 230 volts. This versatile Ameritron feature
maintains optimum voltages on the amplifier components for maximum
performance and life
The ALS-600PS standard power supply uses an input choke to provide low
power factor loading on power lines. This reduces the peak currents drawn from
the line and improves the voltage regulation of the supply. This makes the ALS-
600PS generator and inverter friendly within the acceptable power line frequency
range of 50 to 60 Hz

ALS-600SPS
Power Supply Features
Efficient operation from 100-130 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
Excellent voltage regulation
Exceptional filtering and RFI suppression eliminates receiver birdies common to
most SMPS
Light weight 13 lbs.
Inrush protection
An illuminated cross-needle meter monitors 50V line output voltage and current.
The ALS-606 external power supplies contain 14-volt positive and negative supplies, as
well as a 50-volt 25-ampere continuous (30-ampere peak) main supplies. The ALS-606
PA (power amplifier) module operates from 50-volts, giving a total dc supply rating of
