24 VDC to 12 VDC Converter 20 Amp, ST 340
Item# ST340

Product Description

The model ST 340 DC-DC converter interfaces between 24 Volt DC battery or vehicular power sources and communications and other electrical equipment that is designed to operate from 12 VDC electrical sources. This converter provides harmonic and noise free pure DC power, which makes it ideal for operating the most sensitive communications devices. We are an authorized factory distributor and the product includes a 2 year manufacture's warranty. Made in USA.

Using a DC-DC converter to power 12 volt devices on a 24 volt vehicle is the best choice and does not adversely effect battery life. If a 12 volt device is powered from only one of the vehicle's batteries an imbalance occurs in the charging voltage across the batteries causing one to under charge and the other to over charge. Using a DC-DC converter eliminates the charging imbalance.

The model ST 340 is commonly used to power cell phones, GPS units, radio and audio equipment, lights, etc.

This model is also a popular choice for powering 12 volt electric brake controllers in military vehicles.

If your application requires more than 20 amps at 12 volts see model 362 or 364.
