FIRMWARE VERSION. With no load connected
and power off, use either the GPIB port or RS 232
port (see page 6) to accept remote commands.

If necessary, refer to “Reset Power-up” on page 8
and Figure 5 to configure the GPIB address (default
is 6) or configure the RS 232 baud rate (default is

9600).

Apply power to the unit and send *IDN? query. The
unit responds with a character string containing the
following fields: <Manufacturer>,<Model Voltage­Current Calibration Date>,<Serial Number>, <Firm­ware Version> e.g., KEPCO, BOP1KW 20-50 09/30/

I — DESCRIPTION

The BOP 1KW-GL Series hereafter referred to as
BOP-GL, are true 4-quadrant programmable voltage
and current power supplies, meaning they are capa­ble of both sourcing and sinking power (see Figure

1).

The BOP-GL models 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. These bipolar power supplies
pass smoothly through zero without switching to pro­vide true ± voltage and ± current. These BOP-GL
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 can be controlled
remotely by an analog ±10V input for the main chan­nel (voltage or current), and by a +1 to +10V input
for the limit channels. They can also be controlled
through one of the standard digital interfaces (GPIB
or RS 232) to set voltage and current and the four
protection limits (+voltage, –voltage, +current and –
current.) Output voltage and current can be remotely
monitored via the analog monitor signals present at
the rear panel Analog I/O Port connector, or by using
SCPI commands via either the RS 232 or GPIB
ports.

VI — 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 POWER switch set to off position, connect
the power supply to source power (see “Input
Connections” below).

2. Verify that the power-up switches at the top cover
are set to the factory default positions shown in
Figure 5. This establishes GPIB address 6, stand­alone operation, Voltage mode, Analog Input
enabled and internal ±current limits enabled and
set to maximum.

NOTE: The unit is shipped with load type set to

Active (for inductive loads). To change the
load type refer to the “Reset Power-up” on
page 8. The logic for Remote on/off input
at pin 2 of the Trigger port is set to high (1)
or open circuit for output on, low (0) or
short circuit for output off.

3. Connect a twisted wire pair (either #24 or #22
AWG) to the mating connector for the Analog I/O
port pins 11 and 10. Connect +10V d-c ±0.1mV to
pin 11, referenced to pin 10, then install the mat­ing connector on the Analog I/O port at the rear
panel.

!

4. Connect the power supply to source power. With
no load connected, set POWER switch to the ON
position.

5. Each time the unit is turned on an internal self­test is performed. If the unit passes, it initializes
with the power-up settings established in step 2
and the front panel POWER/FAULT/LIMIT light is
green (power good), the DIGITAL CONTROL light
is not lit (analog input enabled) and the VOLT­AGE/CURRENT light is green (voltage mode),
MASTER/SLAVE light is green (standalone or
master configuration) and the OUTPUT ON light
is lit (output enabled). If the front panel POWER/
FAULT/LIMIT light is red, the unit has failed self­test; contact Kepco for further instructions. If the
unit beeps, or the MASTER/SLAVE or VOLTAGE/
CURRENT light blinks, refer to the BOP-GL Oper­ator Manual for troubleshooting.

6. Connect a digital voltmeter (DVM) with resolution
and accuracy of 0.01% or better to the OUT S and
COM S terminals at the rear panel terminal block.

7. Verify DVM voltage reading matches the nominal
voltage of the unit within 0.01% of rated maximum
voltage.

CAUTION:

DO NOT repeatedly toggle the
POWER circuit breaker/switch as
this may damage the unit.

VII — INSTALLATION

Install units either on a bench or in a 19 inch-wide
rack. For rack mounting: first remove four feet; rack
must provide support at the rear. Optional slides
may be used. Leave the front and rear panels clear
of obstructions to ensure adequate cooling.

INPUT CONNECTIONS. Source power is con­nected to the power supply via three-wire input power using the source power mating connector supplied (see Table 3). This power supply operates from single phase a-c mains power (or between two phases of 3-phase a-c mains power), 230V, 50/60Hz nominal (range: 176 - 264V, 47-63Hz) without any need for range selection. The user must provide a properly sized and rated mains lead (line cord) and service with a current rating compatible with the required input current. Line cords available as accessories are listed in Table 3. Plug the source power connector into the source power inlet connec­tor at the rear panel.

LOAD CONNECTIONS.

CAUTION:

!

Before connecting a load, verify
that power up switch settings (see
“Power-up Settings” on page 8) are
compatible with your load.

Power connections require 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 rear panel (see Figure 3). OUT S
and COM S terminal of the Monitor and Sensing Ter­minal block are for connection of remote sensing
leads (after removing the factory-installed local
sensing links). NOTE: Output Sense lines must be

connected 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
