The FB1000 power supply is designed to provide con-
stant voltage, current, or power in both Manual and
Programmed modes of operation commonly used in elec-
trophoresis applications. One to four sets of elec-
trophoresis cells can be connected in parallel and run
simultaneously. The FB1000 can deliver up to 250W of
total output power. When operating in any constant
mode, the power supply automatically limits the other
parameters to either the power supply maximum, or a
lower limit if set by the user. If any non-constant limit is
reached, the power supply will automatically switch con-
trol modes, controlling the limit parameter. In this way,
the FB1000 protects your electrophoresis cells from dam-
aging over power conditions. The FB1000 power supply
also provides for timed and volt-hour operation in all con-
trol modes, and allows an automatic completion in the
event of a power loss if enabled.
Features
•5-1000V, adjustable in 1 volt steps
•1-500mA, adjustable in 1mA steps
•1-250W, adjustable in 1W steps
•0-90C, adjustable in 1degree C steps
•Automatic control mode crossover
•0-99 hour 59 minute timed run
•0-9999 volt-hour timed run
•Automatic restart if loss of AC power (if enabled)
•Large LCD display

Read and understand this manual completely before
attempting to set up or use this instrument.
This equipment has been designed and tested to conform
to CSA1010 safety standards, as applicable to laboratory
instrumentation. This applies only to the FB1000 when
used as specified in the documentation, in its intended
applications, with Fisher Biotech approved electrophore-
sis apparatus only. Usage in any other manor may not
provide similar performance or safety protection.
This equipment is provided with a 3-conductor, grounded
AC line cord. The protective earth ground is necessary
for safe operation. Do not use any other AC line cord
with this instrument.
The FB1000 is a high voltage power supply capable of
generating dangerous levels of voltage and current during
operation. Exercise caution when working around and
with the electrical connections of this equipment. Always
check electrical connectors, wires, and associated appa-
ratus for any signs of wear or damage before using with
this equipment. Be sure to use only electrophoresis
equipment that is suitably rated for the voltage and cur-
rent capabilities of the FB1000 power supply.
The output of the FB1000 power supply is intended for
connection to electrically isolated electrophoresis appara-
tus only. Use only with electrically isolated electrophore-
sis apparatus with minimum isolation of 1000V. Do not
connect any terminal of the FB1000 output to earth
ground. This may impair the safety protection provided
by the equipment, or cause equipment damage.
The high voltage output of the FB1000 power supply
takes some amount of time to decay when unloaded or
lightly loaded. Wait a minimum of 60 seconds after stop-
ping a run before touching the power supply leads.
This equipment has a protective ground leakage current
of 0.5mA at 120VAC, and 1mA at 230VAC. While signifi-
cantly below the 3.5mA limitation for laboratory instrumen-
tation, some applications and locations require a leakage
current below 0.5mA. Check the specific requirements of
your application before using this equipment.
This equipment is for indoor use only.

Using the Power Supply
Press the dark gray key on the front of the unit to enable/dis-
able the control logic. The LCD display will illuminate and allow
selection of MANUAL or PROGRAM mode of operation as well
as enable/disable automatic power-fail restart. Toggle automat-
ic power-fail restart by pressing the topmost function key to the
right of the display. Select MANUAL or PROGRAM mode using
the function keys to the right of the display (see Programming
section for programming mode description). In manual mode,
the FB1000 preserves the constant setpoint each time you start
a run. The constant parameter is saved independently for each
mode; constant voltage, current, and power.
To change the control mode, press the Exit key. From the
resulting screen, select the new constant parameter using the
function keys to the right of the display.
After selecting a control mode and setting the limit and timed
run parameters if desired, press the Run key to energize the
power supply output. The power supply output will ramp up to
the appropriate setpoint, while not allowing any limit parameter
to be exceeded. If any limit parameter should be exceeded,
then the power supply will crossover control modes, making the
limit parameter the new control setpoint. The run mode display
shows the controlled parameter highlighted, and will automati-
cally change if a crossover has occurred.
To stop a run in progress, press the Run key, the Stop key, or
the gray ON/OFF key. The display will change to "STOP" signi-
fying that the output is no longer energized, and display the
conditions just before the stop. To pause a run in progress,
press the Pause key. The display will change to "PAUSE" sig-
nifying that the output is no longer energized, and that the run
can be resumed. Pressing Run or Pause resumes the run from
the previous point (i.e. for a timed run). Only a run that has
been paused can be restarted. After Stopping a run, or to
change parameters of a (paused) run, you must cycle the con-
trol logic off and then back on by pressing the gray ON/OFF
key.
During a run, the display will show the actual values of voltage,
current, power, and temperature. The time value displays
elapsed time for an untimed run, or time left for a timed run.
The volt-hour value displays the accumulated volt-hour value
for the run.

Volt-Hour Operations
It is possible to enter an amount of volt-hours for the
power supply to provide power, after which it will automat-
ically shut off. Volt-hours is the integration of voltage over
time. Use volt-hour control to provide consistency
between runs.
Set up a constant mode setpoint and limits as described
above. Enter a volt-hour duration of 0-9999 volt-hours. A
volt-hour duration of zero effectively disables volt-hour run
mode.
During a run, the volt-hour value displays the accumulat-
ed volt-hour value for the run.
Automatic Power-Fail Restart
Automatic power-fail restart capability allows a timed or
volt-hour run which is interrupted by loss of AC power to
be restarted automatically, so that the total time/volt-hour
programmed for the run will be met.
To enable power-fail restart, press the top function key
when in the mode selection screen (MANUAL or PRO-
GRAM). The state of power-fail restart will toggle from off
to on or on to off with each keypress.
When AC power is restored during a run in which power-
fail restart is enabled, the display will show "POWER-FAIL
RESTART" for approximately 10 seconds indicating
power-fail restart pending. During this time the output is
not energized, to allow safely stopping the run (by press-
ing Run). After the power-fail restart pending delay is
completed, the power supply output will ramp up to the
setpoint value and the run will continue from that point.
Any number of power interruptions can occur during the
completion of a single run.
If a power-fail restart occurs during the running of a pro-
gram the FB1000 will complete the interrupted step, and
then advance to the next step in the program.
11
Note
Loss of AC power includes switching
off the unit using the power switch
located at the rear of the unit. When
performing timed or volt-hour runs
with power-fail restart enabled, always
use the front panel controls to stop a
run in progress.
OPERATION

Programming
The FB1000 can store 9 programs, each containing 9
steps. A program step is a constant voltage, current, or
power setpoint with any associated limit parameters, and
most importantly a time and/or volt-hour setting. When
running a program step, after the time or volt-hour limit is
reached, the FB1000 will automatically run the next pro-
gram step (if there is one). After all program steps are
completed in a program the FB1000 will shut down. Any
sequence of control mode and timed/volt-hour steps can
be contained in a program. Note that a program step can
contain a zero for the time and volt-hour parameters, in
which case the FB1000 will continue to maintain that set-
point indefinitely (just like the setting had been run from
MANUAL mode).
To enter programming mode from an operating screen,
cycle the control logic off and then back on by pressing
the gray ON/OFF key and selecting PROGRAM. The
FB1000 will display the program screen, which shows the
number of steps contained in the selected program. Use
the function keys to the right of the display to move
through the 9 possible programs. To run the program
starting from step 1, press the Run key. To edit a pro-
gram (including adding a first step to an empty program)
press the function key labeled EDIT. The FB1000 will dis-
play the step screen, which shows the parameters for the
selected step (except when the program is empty in
which case the FB1000 automatically starts entering the
first step as follows). Use the function keys to the right of
the display to move through the 9 possible steps. To run
the program starting from the selected step, press the
Run key. To edit a step press the function key labeled
EDIT. The FB1000 displays the mode selection screen.
Select a constant mode of operation by pressing the
appropriate function key located to the right of the display.
To switch between volts/current/power and time/volt-
hours, press function key F1. To change a parameter,
press the function key located to the right of the display,
next to the parameter you wish to change. The FB1000
will allow a new value to be entered using the keypad
numeric keys. Press the function key labeled "Enter" to
complete the new setting. Press Clear to erase previous
keystrokes. Press Exit to cancel entering a new value.
The FB1000 will not accept any parameter outside of the

Cleaning
Before cleaning the unit, be sure to always turn off AC
power using the switch at the rear of the unit, and then
disconnecting the AC line cord. The front of the unit is
sealed and can be wiped clean with any mild detergent
solution. Avoid harsh cleaners or agents as they may
deteriorate the surface of the tactile membrane keys.
Replacing a Fuse
Before servicing the unit, be sure to always turn off AC
power using the switch at the rear of the unit, and then
disconnecting the AC line cord. The FB1000 power sup-
ply requires no periodic servicing and should provide
years of trouble free operation. Should you need to
replace the fuses proceed as follows:
Turn off AC power using the switch at the rear of the unit,
and then disconnecting the AC line cord. Remove the
fuse holder assembly using a small flat blade screwdriver.
Always replace both fuses with appropriate replacement
