SECTION 1 - INTRODUCTION
1.1 SCOPE OF MANUAL
This manual contains instructions for the installation, operation and servicing of the BOP series
of 1000 Watt rack-mounted, 4-quadrant bipolar, programmable, voltage and current stabilized d-
c power supplies manufactured by Kepco, Inc., Flushing, New York, U.S.A.
NOTE:This manual does not apply to units with Firmware Rev less than 2.0.
1.2 GENERAL DESCRIPTION
The BOP Series (Figure 1-1), hereafter referred to as BOP, are true 4-quadrant programmable
voltage and current power supplies, meaning they are capable of both sourcing and sinking
power. These bipolar power supplies pass smoothly through zero without switching to provide
true ± voltage and ± current. These BOP power supplies use switch mode technology for low
dissipation. A bi-directional, isolating, a-c input power factor correcting (PFC) circuit recuperates
energy sinked from an active load and sends it back into the line to maintain low dissipation.
These BOP power supplies are controlled digitally from a menu-driven front-panel keypad or
one of the standard remote digital interfaces (GPIB or RS 232) to set voltage and current and
the four protection limits (+voltage, –voltage, +current and –current.) A front panel rotary
adjuster allows real-time adjustment of the output. A large LCD displays the settings, mode and
the actual output voltage and current. Additionally, these BOP models can be remotely con-
trolled by an analog ±10V input for the main channel (voltage or current), and a +1 to +10V input
for the limit channels.
BOP models are suitable for driving inductive loads such as large magnets or motors, and for
exercising batteries. They are also suitable for characterizing solar cell arrays, and powering
many electrochemical reactions.
1.3 SPECIFICATIONS
Table 1-1 below indicates parameters that vary for different 1000 Watt BOP models; Table 1-2

NOTE: When connecting active loads, the steady-state voltage of the active load must not exceed the maximum voltage rating of the
BOP. Otherwise the overvoltage protection will shut down the power supply.
