POWER SUPPLY

I — INTRODUCTION

1.1. SCOPE OF MANUAL. This Quick Start Guide

covers simple installation and local operation of the Kepco
100W, 200W and 400W Series of BOP Bipolar Operational
Power Supplies. Full specifications, features and instruc­tions are found in the BOP Operator Manual that can be
downloaded free from the Kepco web site at:

www.kepcopower.com/support/opmanls.htm#bop-op

1.2. DESCRIPTION. Kepco’s BOP are linear stabilizers with two bipolar control channels (voltage or current mode), selectable and individually controllable either by front panel controls, or by remote signals. These two principal control channels are each protected by bipolar limit circuits. The positive and negative current or voltage limit points can be manually set or remotely programmed simultaneously or Individually. Automatic crossover between each principal control channel and the limit channels is provided. Only one principle channel (voltage or current) can control the output at any one time.

The BOP can act as either a source (output voltage is the
same direction as output current) or a sink (output voltage
is opposite that of output current). An example is shown in
Figure 1 where the BOP is programmed to deliver a sine
wave output and the load produces a phase shift between
the output voltage and current.

1.3. OPTIONS. Standard models (M suffix) include ana­log voltage and current meters. Models with a D suffix include digital meters.

1.4. EQUIPMENT SUPPLIED.

• PC 15 connector (MUST be installed at rear panel
to enable local operation).

• 115V a-c Line Cord

1.5. ACCESSORIES (NOT SUPPLIED)

• Slides (Full rack only)

• Rack adapter RA 24 or RA 37 (mount 3/4 rack unit
in 19-inch rack)

II — SAFETY.

Exercise care in making all connections to and from the
BOP terminals.

WARNINGS

1. Remove a-c power from the BOP before making any
connections.

2. Wires and/or cables, connected from the BOP terminals
to external components or programming devices must
be properly insulated and securely terminated on both
sides to make accidental touch impossible. DO NOT
USE BANANA PLUGS WITH EXPOSED SCREWS OR
OTHER EXPOSED METAL PARTS AT THE FRONT
PANEL OUTPUT TERMINALS!

3. The BOP chassis and cover must be safety-grounded to
a reliable a-c source ground. A safety-ground may be
established by using a grounded a-c power outlet or, if
the latter is not available, by means of a separate wire,
from the provided GROUND terminal to a reliable a-c
source ground point.

Units are shipped for 115V a-c operation (105V to 125V
a-c), 50 to 65Hz. For operation at 104V a-c, 208V a-c or
230V a-c refer to the full Operator manual (PAR 1.1).

4. THE COMMON OUTPUT TERMINAL OF THE BOP
SHOULD BE GROUNDED. If for any reason, grounding
of the output is not possible, additional precautions must
be taken to make any access to the isolated output
impossible.

III — INSTALLATION

3.1. UNPACKING. The power supply has been thor-

oughly inspected and tested prior to packing and is ready
for operation. After careful unpacking, inspect for shipping
damage before attempting to operate. Perform the Prelim­inary Checkout (PAR. 3.2). If any indication of damage is
found, file an immediate claim with the responsible trans­port service

3.2. PRELIMINARY CHECKOUT. A simple operat­ing check after unpacking and before permanent installa­tion, is advisable to ascertain whether the BOP has suffered damage in shipment.

1. Install PC15 (supplied) at rear panel. This is required
for local control of the unit.

2. Refer to Safety instructions (see Section IV) and con­nect unit to 115V a-c source; see Operator manual
(PAR 1.1) for different source voltage.

8. Turn the Current Control clockwise through its range,
while observing the front panel Ammeter. The BOP
output current should respond smoothly, from the max­imum negative output current, through zero, to the
maximum positive output current of the BOP.

9. Set A-C POWER circuit breaker/switch OFF. Remove
the short circuit from the output terminals. This con­cludes the preliminary check-out of the BOP.

3.3. INSTALLING THE POWER SUPPLY.

3/4 RACK MODELS. These models are shipped with four
plastic feet installed for benchtop operation. The feet must
be removed for rack mounting. Kepco’s RA 24 or RA 37
can be used to install these models in a standard 19-inch
rack (installation instructions supplied with rack adapter).
Four plastic mounting inserts on the bottom of the chassis
can be used to mount the unit on any flat surface.

3. Set the BOP front panel controls as follows

a. Voltage/Current MODE select switch set to VOLT-

AGE.

b. Voltage Control ON/OFF switch to ON, Voltage

Control to extreme counterclockwise position.

c. A-C POWER circuit breaker/switch to ON.

d. The E

Mode indicator will be “on.”

O

4. Turn the Voltage Control clockwise through its range,
while observing the front panel Voltmeter. The BOP
output voltage should respond smoothly, from the max­imum negative output voltage, through zero, to the
maximum positive output voltage of the BOP.

5. Set A-C POWER circuit breaker/switch OFF.

6. Connect a short circuit between the OUTPUT and
COMMON front panel output terminals.

7. Set the BOP front panel controls as follows:

a. Voltage/Current MODE select switch set to CUR-

RENT.

b. Current Control ON/OFF switch to ON and Current

Control to its maximum counterclockwise position.

c. A-C POWER circuit breaker/switch to ON.

d. The I

Mode indicator will be “on.”

O

FULL RACK MODELS. These models are shipped with
fixed angle brackets and chassis slide support bars
installed and are ready for mounting in a 19-inch rack.

3.4. CONNECTIONS. Connections can be made using either the front or rear panel terminations, but not both.

LOAD CONNECTIONS. Connect the load between OUT­PUT and COMMON terminals. Connections may be made
at either the front or rear panel. Sense connections are

required, either local or remote, must be used; other­wise the unit will not operate.

SENSE CONNECTIONS. For local sensing The OUTPUT
and COMMON terminals are connected to the adjacent
SENSE terminals. The unit is shipped with local sensing
links in place at the rear panel. If load connections are
made at the front panel, remove the installed links from
the rear panel. At the front panel install jumpers between
COMMON and the adjacent SENSE terminal and
between OUTPUT and the adjacent SENSE terminal. If
desired, a link between terminals 5 and 6 at the rear panel
may be installed to enable the Grounding Network.

Remote sensing (connecting the corresponding SENSE
terminals to the OUTPUT and COMMON terminations at
the load instead of at the BOP) can compensate for load
wire losses up to 0.5V per wire. Remote sensing is recom­mended for minimum load effect for a remote load. Use
twisted pairs: #22 AWG for output sense lines and wires
rated for the nominal output current of the power supply
for power leads. See full Operator Manual (see PAR. 1.1)
for remote sensing requirements.
