G123-821 Mini DDV Amplifier


The G123-821 Mini DDV is a +/- 1 Amp output amplifier suitable for driving a Moog Mini DDV. Its bipolar output enables the DDV to produce flow to both ports A and B, an essential feature in a closed loop servo system. Front panel indicators and test points provide ease of set-up and troubleshooting. The Mini DDV Amplifier is housed in a compact DIN rail mounting enclosure and requires a 24V DC power supply.
