CAUTION
If this power supply is used in OEM equipment, the OEM equipment manufacturer is responsible for
attaching appropriate warning labels on the OEM equipment.
Operating the power supply outside the specified limits for input voltage, temperature, or other environmental conditions noted in this manual can damage the power supply and void the warranty.
Safety Messages
The BOP HV protection circuit is designed to protect the load against unregulated high voltages. Upon
sensing a high temperature signal, the protection circuit shuts down the output stage before the overtemperature can destroy the transistors. In addition to that, the protection circuit shuts down the output stage
when there is a lapse of AC input power for more than 8 ms. This feature is provided so as to avoid an
uncontrolled output signal during the shut OFF of the power supply.

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).
SECTION 1 - INTRODUCTION
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 texture. 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.
1.3 ELECTRICAL SPECIFICATIONS, GENERAL
A) INPUT SOURCE REQUIREMENTS: 105 to 125Vac or 210 to 250Vac, 50 to 65 Hz, select-
able by the SOURCE VOLTAGE SELECTOR SWITCH (refer to Section 2, Fig. 2-3). Power
consumption approximately 250 Watts. Power factor: 0.8. The primary circuit is protected
by a fuse.
B) OPERATING TEMPERATURE RANGE: -20°C TO +65°C.
C) STORAGE TEMPERATURE RANGE: -40°C to +85°C.
BOPHV112211 1-1
D) COOLING: Forced air using a d-c fan blowing to the rear of the unit.
E) ISOLATION FROM GROUND: The BOP circuitry, its output and programming terminals
have no d-c connection to the chassis. The COMMON terminal of the BOP can be operated up to 500 volts (d-c or peak a-c) off ground. The common mode current (leakage from
output to ground) is less than 50µA (rms) or 200µA (p-p) at 115Vac power input, 60 Hz.

NOTE: In this instruction manual, Kepco will follow the NEMA standards for d-c Power Supplies
and speak of the “Output Effects,” caused by changes in the “Influence Quantities.” The
“Output Effects” are specified either as a percentage change, referred to the maximum
specified output voltage (E
) or current (IO), or as an absolute change (∆EO, ∆IO), directly in
O

D) The BOP output effects, in response to the tabulated variation in the INFLUENCE QUAN-
TITIES, are given in Table 1-2 for the built-in input and feedback resistor values of the voltage and current channel preamplifiers.The tabulated OFFSET values (see Table 1-2) may
be used to calculate the BOP output effects if the BOP voltage or current channel is
remotely programmed and different values for the feedback resistors (Rf) and the input
resistors (Ri) are used. In this case, the tabulated preamplifier offsets and the values of the
feedback and input resistors are combined in an “Error Equation”, which represents the
“Worst Case” output effect for the application at hand:
