For new programs and most military / industrial / commercial applications, please contact us for a quote on modern replacements.[/vc_message][vc_column_text]The RCGL3K (pure sine wave) inverters are intended form commercial, industrial or military applications wherever standard utility-like power is needed at 50 or 60 Hz. These inverters are ideal for running electronic loads such as computers, monitors, printers, telecom systems, radios, fluorescent lamps from batteries, field generators, and solar electro-voltaic panels. They can also drive hand drills, motors and small compressors. This unit can be ruggedized against shock, vibration and humidity optionally for mobile applications.[/vc_column_text][/vc_column][/vc_row]
