SECTION 1 - INTRODUCTION
1.1 SCOPE OF MANUAL
This manual contains instructions for the installation and operation of the Models BOP 500M,
BOP 500DM, BOP 1000M and BOP 1000DM Bipolar Operation Power Supplies, manufactured
by Kepco, Inc., Flushing, New York, U.S.A.
1.2 GENERAL DESCRIPTION
The Kepco Model BOP 500M and BOP 1000M are high voltage power sources, which combine
the capabilities of fast programmable power supplies with a Class A output stage, which can
respond bidirectionally from zero. Models with the DM suffix are similar to M suffix models,
except that the analog front panel meters are replaced by digital meters. The “BOP” can be
operated in a “Voltage Stabilizing” or “Current Stabilizing” operating mode (selectable by a front
panel switch). The BOP incorporates two separate control channels, for local (front panel) or
remote control of the output current and the output voltage. In addition, bounding currents for
bipolar voltage and current limiting are provided which may be adjusted manually (by front panel
controls) or can be remotely programmed. All control and bounding channels are connected to
the bipolar (Class A) output stage via an “EXCLUSIVE-OR” gate, so that only one circuit is in
control of the BOP output at any one time. Some applications are listed below:
A) VOLTAGE MODE OPERATION. (Current limiting either front panel adjusted or remotely
programmed using the current limiting channel).
1) High speed, bipolar d-c voltage source (remote or locally controlled output).
2) Scaling or summing amplifier with or without d-c bias.
B) CURRENT MODE OPERATION. (Voltage limiting either front panel adjusted or remotely
programmed using the voltage limiting channel).
1) High speed, bipolar d-c current source (remote or locally controlled output).
2) Amplification of a-c currents with or without d-c bias.
The main chassis of the Model BOP Operational Power Supply/Amplifier is constructed of
plated steel. The wrap-around cover is perforated steel, plated and painted in a dark gray tex-
ture. The front panel material is aluminum, treated and painted light gray (Color 26440 per Fed.
Std. 595). The major part of the circuitry is located on plug-in type circuit boards for convenient
access.
