When you first turn on your amplifier, a
massive inrush current gushes in. Your house lights flicker as you hear loud
"thump'' from your amplifier. This terrible inrush current stresses all
your power supply components to their limits. Your cold tube filament suffers
abusive thermal shock. Eventually, this massive inrush current will damage
your amplifier. Ameritron's Step-Start Inrush Current Protector
stops
damaging inrush current. By starting your linear amplifier through a high
power current limiting resistor and then shorting the resistor with a relay,
you get a start up sequence that's easy on your tube and power supply
components.
Now you can add this protection to your amplifier
without complicated wiring -- you don't even have to take the cover off.
Simply plug your amplifier power cord into the Ameritron Inrush Current
Protector. By limiting heavy inrush current to safe low level, you'll get a
longer lasting amplifier.
You might avoid replacing expensive tubes and
components. Avoiding just one repair job could pay for this extended
protection.
Momentary high-voltage "spikes" in
the ac line can also cause damage to your amplifier. The Ameritron Inrush
Current Protectors have built-in varistors to absorb these spikes before they
can cause damage.
Works with nearly all linear amplifiers. Ameritron
ICP-120, for 120 volt wired amplifers. Limits current to 12 amperes during
heavy draw inrush period. 20 amperes continuous operating current. Ameritron
ICP-240, for 240 volt wired amplifiers.
