Introduction
Thank you for selecting a Fisher Scientific FB300 Electrophoresis power supply. This manual describes the operation of the FB300. The power supply that you have purchased is the most productive and easy-to-use unit available anywhere. This manual should answer any questions that might arise in operating your power supply; however, don't hesitate to call our Fisher Lab Equipment Technical Support Hotline at 1-800-943-2006 or 1-800-926-0505 if you need any assistance.
The FB300 power supply is designed to provide constant voltage or constant current output to apparatus used in electrophoresis applications. One to three sets of electrophoresis cells can be connected in parallel and run simultaneously. The FB300 can deliver up to 75W of total output power. When operating in constant voltage or constant current mode, the power supply automatically limits the other parameter to either the power supply maximum, or a lower limit if set by the user. If this non-constant limit is reached, the power supply will automatically switch control modes, from constant voltage to constant current, or vice versa. In this way, the FB300 protects your electrophoresis cells from damaging over power conditions. The FB300 power supply also provides for timed operation in either voltage or current modes, and allows an automatic completion in the event of a power loss if enabled by the user.

Getting Started
Select a location that allows for 3" clearance behind the power supply, and comfortable reach of the front panel controls and cell connections. Do not block the vented area of the case - on the front bottom of the unit, or the fan area at the rear. Connect the power supply to a 3-prong grounded AC outlet, using the AC cord provided with the unit only electrophoresis apparatus to the power supply, making sure to match the red positive lead to the red positive jack, and the black negative lead to the black negative jack. Similarly, connect one or two more electrophoresis apparatus to the power supply if you plan to run more than one in parallel. Power the unit on using the AC power switch located at the rear of the unit, next to the AC line cord entry.

Using the Power Supply
Press the gray key on the front center of the unit to enable the control logic. The 3-digit display will illuminate and show the setpoint value of the last saved run setup. The FB300 preserves the run settings each time you start a run. One set of conditions is saved for each mode, constant voltage or constant current. The setpoint value, limit parameter, time duration, and power-fail restart setting is saved. This allows convenient setup for repetitive runs.
To change the control mode, press the constant key. This key toggles control from constant voltage to constant current. Each time, the FB300 will display the last saved setpoint value for that particular mode.
After selecting a control mode, either constant voltage or current, and setting the limit and timed run parameters if desired (see Constant Voltage/Current Operations) press the Run key to energize the power supply output. The power supply output will ramp up to the appropriate setpoint, while not allowing the limit parameter to be exceeded. If the limit parameter should be exceeded, then the power supply will crossover control modes, making the limit parameter the new control setpoint. The front panel constant mode LED indicator will change to indicate that a crossover has occurred.

FB300-2 MANUAL Page 5 7608001 Rev A 8/02
To stop a run in progress, press the Run key or the gray ON/OFF key. The display will change to "OFF" signifying that the output is no longer energized. Pressing run again resumes the run from the previous point (i.e. for a timed run). Pressing any other key will return to setup mode in either constant voltage or constant current mode as appropriate.
During a run, the display will automatically cycle between voltage, current, and time displays. Voltage and current is displayed as actually measured by the FB300. When displaying the controlled setpoint, i.e. voltage for constant voltage control, the arrow keys can be used to modify the setpoint. The limit parameter cannot be changed during a run. The time parameter displays elapsed time for an untimed run, and time left for a timed run.
Constant Voltage Operations
Press the constant key (labeled K) until the LED indicating "Volts" is illuminated. Each time the constant key is pressed, the FB300 will display the last saved setpoint value for that particular mode. Use the UP and DOWN arrow keys to change the setpoint to the desired value (10-300 volts). The FB300 will not allow setting a voltage setpoint outside of the allowed range. Press and hold either arrow key to quickly change the setpoint.
The limit parameter, in this case current, is normally set to the power supply maximum value of 400 mA. To set a lower limit value, press the Set key until the LED indicating "mAmps" is illuminated. Use the UP and DOWN arrow keys to change the limit to the desired value (4-400 mA). The FB300 will not allow setting a current limit outside of the allowed range.
In addition, the FB300 will never exceed the maximum power output specification of 75W. When starting a run, the power supply calculates a maximum limit parameter, above which the power supply maximum power output rating would be exceeded. If this value is lower than the limit setpoint entered, the FB300 will use this lower limit parameter.
Constant Current Operations
Press the constant key (labeled K) until the LED indicating "Amps" is illuminated. Each time the constant key is pressed, the FB300 will display the last saved setpoint value for that particular mode. Use the UP and DOWN arrow keys to change the setpoint to the desired value (4-400 mA). The FB300 will not allow setting a current setpoint outside of the allowed range. Press and hold either arrow key to quickly change the setpoint.
The limit parameter, in this case voltage, is normally set to the power supply maximum value of 300 volts. To set a lower limit value, press the Set key until the LED indicating "Volts" is illuminated. Use the UP and DOWN arrow keys to change the limit to the desired value (10-300 volts). The FB300 will not allow setting a voltage limit outside of the allowed range.
In addition, the FB300 will never exceed the maximum power output specification of 75W. When starting a run, the power supply calculates a maximum limit parameter, above which the power supply maximum power output rating would be exceeded. If this value is lower than the limit setpoint entered, the FB300 will use this lower limit parameter.
Timed Operations
It is possible to enter an amount of time for the power supply to provide power, after which it will automatically shut off. Use this feature for timed runs.
Press the Set key until the LED indicating "Time" is illuminated. Use the UP and DOWN arrow keys to change the time duration to the desired value (0-999 minutes). A time duration of zero effectively disables timed run mode.
When running a timed run, the time parameter displays the time remaining in the run. When running a non-timed run, the time parameter displays the elapsed time during the run
FB300-2 MANUAL Page 6 7608001 Rev A 8/02
Automatic Power-fail Restart
Automatic power-fail restart capability allows a timed run which is interrupted by loss of AC power to be restarted automatically, so that the total time programmed for the time parameter will be met. NOTE: Loss of AC power includes switching off the unit using the power switch located at the rear of the unit. When performing timed runs with power-fail restart enabled, always use
the front panel controls to stop a run in progress.
To enable power-fail restart, press and hold the Set key when changing to the time parameter (from the current parameter). While continuing to hold the Set key, simultaneously press and release the UP arrow key. The display will show "PF" momentarily to indicate power-fail restart is active. Whenever power-fail restart is enabled, "PF" is displayed briefly as the time parameter is selected by pressing the Set key. The power-fail restart feature can be enabled either before or after changing the time duration to the desired value (0-999 minutes). Setting the time duration to zero will automatically disable power-fail restart (if you have enabled power-fail restart before setting a time value, and want to disable it, then simply increment and then decrement the time parameter back to zero to disable power-fail restart).
When AC power is restored during a timed run in which power-fail restart is enabled, the display will show "PF" for approximately 10 seconds indicating power-fail restart pending. During this time the output is not energized, to allow safely stopping the run (by pressing RUN). After the power-fail restart pending delay is completed, the power supply output will ramp up to the setpoint value and the time will continue from that point. Any number of power interruptions can occur during the completion of a single run.
Cleaning
Before cleaning the unit, be sure to always turn off AC power using the switch at the rear of the unit, and then disconnect 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.

Troubleshooting and Error Indications
The FB300 detects and reports several events and conditions that are considered errors. The FB300 will stop any run in process and display "EXX" where XX is one of the below listed errors. When the FB300 is displaying an error indication, press the gray ON/OFF key to clear the error and return to setup mode, or press the Run key to resume the run (after correcting the cause of the error). Note that loss of AC power during a run is considered an error condition. Always stop a run before turning off AC power to the FB300.
