I — DESCRIPTION.
The BOP 1KW-MG/ME 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 61).
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, isolat-
ing, 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 remote
digital interfaces (GPIB or RS 232 on MG models, LAN
or RS 232 on ME models) to set voltage and current
and the four protection limits (+voltage, –voltage, +cur-
rent and –current.) A front panel rotary adjuster allows
real-time adjustment of the output. A large LCD dis-
plays the mode of operation, the settings, and the
actual output voltage 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 electrochemical
reactions. Models with L suffix have been optimized for
exceptionally low current ripple and noise and
improved stability (drift and temperature), making them
ideal for driving inductive loads, such as large magnets
or motors.
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 “Load Connec-
tions.” on page 5. If any indication of damage is found,
file an immediate claim with the responsible transport
service.

(1) Models with MG suffix include GPIB and RS 232 digital interfaces. Models with ME suffix include LAN and RS 232 digital interfaces.
(2) 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.

NOTES: 1. MEL suffix models include LAN and RS 232 interfaces. MGL suffix models include GPIB and RS 232 interfaces.
2. 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.
3. The output impedance of the MEL/MGL models is identical to the output impedance of corresponding ME/MG models.
