Since 1976, Astron Corporation has been a premier manufacturer of Linear Power Supplies. Made in the USA, their Linear Power Supplies have reliably served Commercial and HAM operators alike for over forty years. In 1980, Astron brought on a line of DC-DC converters. Their heavy-duty converters support an input voltage range of 24-72VDC and can be used anywhere from golf carts to heavy machinery. They also added a new Isolated model to Their DC-DC line. The ISO models were primarily designed for use with Electric Forklifts and positive ground systems. In 1996, Astron adopted Switching technology with its new line of Switching Power Supplies. Their Switching models are a great size efficient alternative to our Linear Power Supplies. Today, Astron is family owned and operated out of Irvine, California and distributes worldwide.
