Special Features:

Length 17.18 inches; width 7.03 inches; height 5.03 inches; protected against output overvoltage, output over/under frequency, overtemperature, short circuit, input loss of phase, and input over/undervoltage; remote on and off; fault annunciation; low input current harmonics

Properties:

An electronic device having frequency mixing circuits and an integral oscillator which mixes the incoming frequency(ies) with the oscillator frequency, the resultant frequency(ies) being a combination of the two sources. Includes equipment that performs these functions at either radio or power line frequencies. Excludes items that change frequency by means of rotating equipment or rectifier and switching or keying circuitry.
