ALS-600PS Power Supply Features
ɀ
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).
ɀ
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
ɀ
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
ɀ
Step-start to limit stress on power supply components
ɀ
An illuminated cross-needle meter monitors the 50V line output voltage and
current
ɀ
Weight 33 lbs.
ALS-600SPS Power Supply Features
ɀ
Efficient operation from 100-130 volts ac (12 amperes typical at full output power)
ɀ
Low standby and receive power drain, typically less than 100 watts
ɀ
Generator and inverter friendly with acceptable power line frequency range 40 to
400 Hz
ɀ
Inrush protection
ɀ
Fully-regulated current-limited outputs
ɀ
Excellent voltage regulation
ɀ
Exceptional filtering and RFI suppression eliminates receiver birdies common to
most SMPS
ɀ
Light weight 13 lbs.
ɀ
An illuminated cross-needle meter monitors 50V line output voltage and current.
The ALS-706 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-706
PA (power amplifier) module operates from 50 volts, giving a total dc supply rating of
1250 watts average power and 1500 watts peak dc power. The 14 volt supplies are for
illumination, bias, and control functions.
Power supply to amplifier interconnections are through a heavy-duty cable using reliable
Cinch Jones connectors.
