The Labworks PA-141 Linear Power Amplifier has two operational
modes. The amplifier can be front panels switched to allow use as either a wide-band, highly damped
voltage source, or as a high impedance current source. Optional, internal
DC field power supplies can be supplied for use with Labworks ET-140 and
ET-127 Shakers.
PA-141 Amplifiers feature protection from both over current and over temperature ensuring long term reliability. The amplifier has full interlock capabilities as well as peak voltage and RMS current bar graphs to monitor output.
These features are integrated to provide full "big system" performance with the convenience of a single chassis. |
