Trek Model 615-10
±10 kV (±20 kV p-p) High-Voltage AC/DC Generator
The Trek Model 615-10 is a precision high voltage AC/DC generator
and amplifier system used in a broad range of R&D and production
applications. In the constant voltage mode, the 615-10 generates
constant amplitude waveforms with or without DC bias. In the constant
current mode, it generates constant amplitude AC current waveforms,
with or without DC bias and in amplifier mode, an analog voltage input
connector is provided to apply external AC or DC signals.
The Model 615-10 provides many extra features, along with Trek’s
exclusive instrument control and an interface to be used in remote
