Product Description
In the world of antique automobile radios, a power inverter is a crucial component that facilitates the conversion of direct current (DC) from a vehicle's electrical system into alternating current (AC), enabling the operation of the radio and associated components. This conversion is essential because many antique radios and audio equipment require AC power to function properly.
Typically, antique car radios operate on a 6-volt DC electrical system, which was standard in vehicles manufactured before the widespread adoption of 12-volt systems. However, most vintage radios require higher voltage to power their vacuum tubes and other electronic components effectively. This is where the power inverter comes into play.
The power inverter consists of electronic circuitry that converts the low-voltage DC input into the higher-voltage AC output required by the radio. It utilizes transformers, capacitors, and other components to achieve this voltage conversion efficiently and safely.
One common type of power inverter used in antique car radios is the vibrator power inverter. This device employs an electromechanical vibrator unit to generate the alternating current needed to power the radio. The vibrator unit rapidly switches the polarity of the DC input, producing an oscillating current that is then transformed into AC voltage by the inverter circuitry.
Another type of power inverter commonly used in antique car radios is the solid-state inverter. Unlike vibrator inverters, solid-state inverters use semiconductor devices such as transistors and diodes to convert DC to AC power. Solid-state inverters are generally more reliable and efficient than vibrator inverters, making them a popular choice for modern retrofits and restorations.
In addition to powering the radio itself, power inverters may also provide AC power for auxiliary components such as external amplifiers, speakers, and other audio equipment. This allows enthusiasts to customize their vintage car audio systems while maintaining the authentic appearance and functionality of the original radio.
Overall, power inverters play a vital role in enabling the operation of antique automobile radios, allowing enthusiasts to enjoy the nostalgic sound of AM broadcasts and vintage music while cruising in their classic cars.
RUN 12 VOLT ACCESSORIES ON 6 VOLT SYSTEMS!
Note: Our Power Inverters and Voltage Boosters are not intended to run motors, solenoids, ignition coils, door locks, lights, fans, trailer brakes, power antennas, power seats, wipers or other inductive loads.
POSITIVE GROUND POWER INVERTERS
Operate modern 12 volt negative ground accessories from positive ground 6, 8, or 12 volt electrical systems! Our Power Inverters are very small (1'"'1'"'1'"), lightweight (only about 9 oz), quiet, and extremely efficient. They use a common ground, so isolation is not necessary. Current draw is negligible when no load is applied (quiescent current is about 10 milliamps), so they are ideal for memory maintenance or alarm systems that must be left on for long periods of time without discharging the vehicle battery. Overload and Reverse Polarity protected for long reliable life.
Possible uses include: Radar Detectors, CB radios, Mobile Phones, Modern Stereo Radios, Alarm Systems (Control only), CD and Cassette Players.
