I — DESCRIPTION.
The BOP 1KW-MG Series 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 (see Figure 1).
These bipolar power supplies pass smoothly
through zero without switching to provide true ± volt-
age and ± current. These BOP power supplies use
switch mode technology for low dissipation. A bi-
directional, isolating, a-c input power factor correct-
ing (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 adjust-
ment of the output. A large LCD displays the mode
of operation, the settings, and the actual output volt-
age and current. Additionally, these BOP models
can be remotely controlled 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 electrochemi-
cal reactions.

II — UNPACKING.
This instrument has been thoroughly inspected and
tested prior to packing and is ready for operation.
After careful unpacking, inspect for shipping damage
before attempting to operate. Perform the “Prelimi-
nary Operational Check.” on page 5. If any indication
of damage is found, file an immediate claim with the
responsible transport service.

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.
