POWER SUPPLY
This guide gives a brief introduction to the BOP 2KW-MG/ME/MGL/MEL Power supply, shows simple load connections, and
allows you to verify the power supply is working. The guide also shows you how to use the front panel controls to perform the
most commonly used functions.
BOP 2KW models with MG and ME suffixes are identical except that the MG units have a factory-installed GPIB interface and in
the ME units the GPIB interface is replaced with a LAN interface. BOP-MG/ME models with an L suffix have been optimized for
better performance when driving inductive loads such as large magnets or motors. Models with an N suffix have an integral rack
mountable case that replaces the wheeled cabinet Unless otherwise noted this guide applies to all models.

I — DESCRIPTION.
The BOP 2KW-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 1). These
bipolar power supplies pass smoothly through zero
without switching to provide true ± voltage and ± cur-
rent. 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. Models with an N suffix have an integral
rack mountable case that replaces the wheeled cabinet
II — UNPACKING.
This instrument has been thoroughly inspected and
tested prior to packing and is ready for operation. BOP
2KW models are shipped in a special shipping crate,
Kepco P/N 213-0104, except N option units are
shipped in a cardboard box. CAUTION: N option units
weigh over 110 lbs and require two people to lift
safely. For units in a crate refer to the unpacking/pack-
ing instructions shown in Figure 12 on page 18 of this
manual to unpack the unit without damaging the ship-
ping crate. It is recommended that the shipping crate
be retained for future shipment when needed. Once the
unit is unpacked, a hoist is recommended to lift the unit
from the base (four holes for eyebolts are provided at
the top of the cabinet). After careful unpacking, inspect
for shipping damage before attempting to operate. Per-
form the “Installation.” on page 5. If any indication of
damage is found, file an immediate claim with the
responsible transport service.

V — PRELIMINARY OPERATIONAL CHECK.
A simple operational check after unpacking and before
equipment installation is advisable to ascertain whether
the power supply has suffered damage resulting from
shipping.
1. With both control and power boost section
POWER switches set to off position, connect the
power supply to source power (see “Input Con-
nections.” on page 5).
2. With no load connected, set both control and
power boost section POWER switches to the ON
position. Each time the unit is turned on an inter-
nal self-test is performed. If all tests pass, the unit
goes into the default mode. If a failure occurs, the
failure is displayed. Figure 5 shows the factory-
configured power on defaults displayed on the
LCD.
3. Connect a digital voltmeter (DVM) (resolution and
accuracy of 0.01% or better) to the OUT S and
COM S terminals at the BOP 2K rear panel termi-
nal block.
4. Use the keypad to enter the rated maximum volt-
age of the power supply (e.g., enter 144 for a
model BOP 144-14MG) and press ENTER. If
STANDBY indicator is lit, press STANDBY key.
5. Verify DVM voltage reading agrees with pro-
grammed voltage within 0.03% of rated maximum
voltage and agrees with displayed voltage on
LCD within 0.05% of rated maximum voltage.

VII — INSTALLATION.
RACK MOUNTING (N SUFFIX ONLY). N Suf-
fix models may be mounted in a 19-inch wide rack as
described in the Operator Manual CAUTION: Before
rack mounting models with N suffix, refer to Opera-
tor Manual for safety precautions.
WIRING. A cable access opening is provided at the
left side of the control section rear panel (see Figure
10) to allow cable connections through the cover for
Analog control, Trigger, RS-232, GPIB, (MG models)
and LAN (ME models).. For convenience when making
connections to the control section rear panel (Figure 6),
remove control section rear cover (four screws), thread
the cable(s) through the access opening and connect
to rear panel as needed, then reassemble rear cover.
INPUT CONNECTIONS. Source power is con-
nected to the power supply via three-wire input power
connected to the three Eurostyle terminal blocks on the
rear panel. This power supply operates with an input a-
c voltage in the range of 176 - 264V/47 - 63Hz without
any need of range/frequency selection. The unit can be
supplied from either a single phase, or between phases
of a 3-phase a-c system as long as the input voltage is
within the range specified above. The user must pro-
vide a properly sized and rated mains lead (line cord)
and service with a current rating compatible with the
rated input current (19A a-c maximum).
LOAD CONNECTIONS. Power connections re-
quire wires that are properly rated for the nominal output
current of the unit.
Connect the load to the OUTPUT
and COMMON power terminals on the BOP 2KW Out-
put Terminal Block on the rear panel (see Figure 10).
OUT S and COM S terminals of the Sense/Monitor Ter-
minal block are for connection of remote sensing leads
(after removing the factory-installed local sensing
links). NOTE: Output Sense lines must be con-
nected for proper operation, either locally, or at the
load (remote). Also use OUT S and COM S to monitor
voltage at the load using external equipment such as a
DVM, oscilloscope, etc. Use OUT MON and COM
MON to monitor voltage at the BOP output. Use twisted
wire pairs or wires that are tied together for both output
power and output sensing connections.
It is critical that configurations comprised of BOP, load,
and external programming devices, have a single
earth-ground point. Observe the following caution and
refer to the applicable BOP 2KW-MG Operator Manual
for earth-ground recommendations. Failure to
observe this caution will void the warranty!
CAUTION: Never connect both the load
terminal tied to the BOP COM terminal
and the programming device common
to earth-ground. This compromises
accuracy and will cause catastrophic
damage to the BOP if the connection
between BOP COM and the load termi-
nal tied to earth-ground is lost.
LOCAL SENSING (FACTORY DEFAULT).
Unit is shipped with local sensing links installed: OUT S
connected to OUT MON and COM MON connected to
COM S at the BOP 2KW Sense/Monitor Terminal Block
(see Figures 7A and 10).
REMOTE SENSING SELECT. First remove the
factory-installed local sensing links between OUT S
and OUT MON and between COM MON and COM S at
the BOP 2KW Sense/Monitor Terminal Block. Then
connect OUT S and COM S lines from the BOP 2KW
Sense/Monitor Terminal Block to the load (see Figure
7B) using #22 AWG wire, twisted pair.
ANALOG I/O CONNECTIONS. The Analog I/O
Port connector, located on the control section rear
panel of the BOP 2KW power supply (see Figure 6),
provides access to analog programming inputs which
can control the mode of operation (voltage or current),
output voltage or current, and establish positive and
negative voltage and current limits. An output analog
corresponding to output current is also provided. Refer
to Operator’s manual for details.
TRIGGER CONNECTIONS. The Trigger Port
(see Figure 6) provides for an external trigger input for
use with SCPI *TRG and TRIG commands. Refer to
Operator’s manual for details.
GPIB CONNECTIONS (MG SUFFIX). Your
computer must have a GPIB interface card installed.
Connect the power supply to the computer’s GPIB
interface card. Use a standard GPIB interface cable at
the GPIB port on the rear panel (see Figure 6).
The default GPIB address is 6; refer to the Operator’s
Manual to change it.
LAN CONNECTIONS (ME SUFFIX ONLY).
Connect the BOP 2KW to a Microsoft Windows-based
computer via the LAN connector (see Figure 6). Use a
standard ethernet cable whether using a router or hub,
or connecting the BOP 2KW directly to a computer.
The BOP 2KW-ME is Auto-MDI-X enabled and does
not require a crossover cable for direct connection. For
Unix and Safari connections see full Operator Manual
(refer to “Accessing Manuals.” on page 1).
