1620A High Current Capability - Parallel Operation

The Ballantine Model 1620A Transconductance Amplifier has the capability of being safely connected in parallel for very high current applications. Due to the unique protection and internal sensing capability that is designed into this instrument, there is an extensive capability for the high current user. Some of this capability is as follows:

1620A: Standard Current Parameters

Multiple 1620A's Connected in Parallel: Current Parameters
(Parameters below are typical for six 1620A's connected in parallel)

Multiple 1620A's may be safely connected in parallel on any current range and driven from any signal source. The only limitation to reproduction of the voltage as a current waveform is the compliance voltage limitation created by inductive loads. The 1620's may be operated CONTINUOUSLY or PULSED without detrimental effects.
