Kepco BOP20-20M

The Kepco BOP20-20M, while a fully rated power supply (20V, 20A), is also a high-powered operational amplifier with full 4-quadrant, bipolar operation. The output is capable of both sustained DC and the replication of arbitrary AC waveforms.

The voltage and cur outputs can be controlled smoothly and linearly through the entire rated plus and minus ranges, passing smoothly through zero with no polarity switching.

The BOP20-20M is a  high speed power operational amplifier that can be used to provide dynamically agile voltage for test and simulation. It is not a general purpose power supply. By the nature of the bipolar high speed design, it does not have any energy storage noise discriminating output capacitors. To realize the full high speed potential of the BOP20-20M, the load characteristics should be mainly resistive. If the load is capacitive, (>0.1 microfarad), the BOP20-20M must be slowed to avoid oscillation. This is accomplished in voltage mode by increasing the value of the feedback capacitance. Special terminals on the user port are available to slow the BOP for optimum current-mode stability into inductive loading.

Features of the Kepco BOP20-20M include:

• Source and sink 100% of their cur rating.
• Separate control circuits for voltage and cur with automatic crossover to cur and voltage limits.
• All controls and flag signals accessible through a 50-terminal userport at the rear.
• Zeroable preamplifier available for scaling and summing external signals.
