The transformer isolated Galaxy Series Inverters are extremely rugged by design, and feature an optional advanced Internal Suppression Filter Network (ISFN) to suppress the significant transients usually associated with rail and military applications. The units are also extremely reliable, designed to provide many years of service in harsh shock, vibration, humidity, and EMI environments.
