POWER SUPPLY FEATURES
ALS-600PS
Multi-voltage heavy duty transformer.
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.
Choke input filtering.
The ALS-600PS standard power supply uses an input choke to
provide a low power factor to the power lines. This reduces the peak currents drawn from
the line and improves the voltage regulation of the supply.
ALS-600SPS
Light weight
. The ALS-600SPS is a light weight switching power supply to use with the
ALS-600 amplifier. The switching supply weighs 3 times less than the choke type power
supply. The ALS-600 amplifier with the switching power supply is ideal for travel.
Hash free
. The specially designed switching and filter circuit makes the power supply
hash free.
Simple power line voltage options.
The power supply will safely operate from 90-135
Vac in the 120 setting and 185-260 in the 240 Vac setting.
ALS-600PS and ALS-600SPS
Step-start circuit.
This circuit uses a relay and resistor to limit the inrush current to the
power supply. This circuit extends the life of the power supply components.
Current and output voltage metering.
An illuminated cross needle meter monitors the
output voltage and current of the 50 volt output line.
GENERAL INFORMATION
Amplifier
The Ameritron ALS-600 is a 600 nominal watt output, solid state, linear amplifier using
state-of-the-art, high voltage, RF TMOS FET devices in the power output section. The
ALS-600 provides continuous frequency coverage from 1.5 through 22 MHz with no
tuning adjustments. Broad band 5 pole low pass filters provide output harmonic
suppression in excess of all FCC requirements. Export modifications are available to
extend operation up to 30 MHz with a copy of a valid amateur license.
