SECTION 1 - INTRODUCTION
1.1 SCOPE OF MANUAL.
This manual contains instructions for the installation and operation of the BOP 5-20DL 100 Watt
Bipolar Operational Power Supply manufactured by Kepco, Inc., Flushing, New York, U.S.A.
The L suffix indicates that the unit is optimized to drive large inductive loads in a stable manner.
Not that throughout this manual E

1.2 GENERAL DESCRIPTION.
Kepco Series BOP Bipolar Power Supplies are fully dissipative, linear stabilizers for laboratory
and systems applications. The BOP is an all solid-state design, featuring IC operational amplifi-
ers in the control circuit section and silicon power transistors mounted on special fan-cooled
heat sinks in the complementary power stage.
The BOP has two bipolar control channels (voltage or current mode), selectable and individually
controllable either from their front panel controls, or by remote signals. Each of the principal con-
trol channels is protected by bipolar limit circuits. In these limit circuits the positive and negative
current or voltage limit points can be manually set or remotely programmed simultaneously or
individually. Automatic crossover between each principal control channel and its associated limit
channel is provided.
All control and limit channels are connected to the complementary output stage via an EXCLU-
SIVE OR gate, so that only one channel is in control of the BOP output at any one time. The
BOP output can be programmed over its full output range by a ±10 volt signal applied to either
one of the inputs to the voltage or the current channel. The limit control channels can be
remotely controlled by a 0 to +10 volt signal applied to their respective inputs. Two uncommitted
preamplifiers, with both inverting and non-inverting inputs available at the Rear Programming
Connector, can scale any programming source to the required input levels. Zero adjustments for
both amplifiers are provided.
The BOP is a fast programmable power supply. The dynamic specifications, given in Table 1-3,
are valid for resistive loads, while those shown in Table 1-5 are for a benchmark inductive load
of 2mH, with the BOP operating in current mode.
