2 FEATURES
Microprocessor controlled switching Power Supply

Last settings are automatically restored at power up.

The PS 304 XL is equipped with an automatic restart system in case of
mains failure.
When the power returns, an audible alarm sounds for 10 seconds and
the power automatically restarts with the previous set values.
If during the power failure the electrophoresis unit is disconnected from
the power supply, the alarm still sounds when the mains supply returns.
Because no load is connected the power supply will immediately shutdown and set the output to zero.

Direct reading of programmed set values and actual values before and
during the cycle.

Volt and mA adjustable during a cycle.

Stabilisation and automatic crossover between the parameters according
to the set limitation values and when output limits are reached. 2 Red
LED indicate the constant mode.

2 operating modes: constant voltage - constant current.

2 LED Displays for set and output Volt, Current.

Settings by tactile switches on moisture resistant membrane panel.

Battery-backed memory feature "save" last output set values in the event
of a power failure or when the run is terminated and the unit is turned off.

4 recessed safety output jacks allow simultaneous operation of 4
electrophoresis units.

Fault detection and 500 µA current leakage detection or no load
automatically shuts down output and indicates the fault by STOP LED
blinking and audible alarm.

4 SAFETY PRECAUTIONS
Delicate instument! Handle with care!
Danger! High voltage!
The power supply is capable of delivering dangerously voltage and has
to to be operated by qualified technically trained personnel. Please
read the entire users´s manual thoroughly before operating this unit.
Take care as the mode of operation is continuous.
Make sure that the on/off switch of the Power Supply is always free
accessible.
The unit must be earthed. Use only the line cords supplied with the unit
for safe operation. The use of a line cord other than this supplied by the
manufacturer may result in user hazard.
For UK users, check the mains plug of the line cord to make sure it is
equipped with a protection fuse not exceeding 3 A. Connect the line
cord directly into a properly rated, 210/250 VAC 50/60 Hz or 105/125
VAC 50/60 Hz wall outlet.
For connection between the power supply and the electrophoresis
equipment, use only the safety output leads equipped with black and
red recessed plugs.
Check the power cords and the black and red recessed safety jacks
periodically to make sure that they are in good condition. Do not use
cords which are cracked, nicked or in otherwise poor condition.
The power supply ust only be connected to electrophoresis equipment
manufactured with built-in safety protected male plugs.
Always make all connections between the power supply and the
electrophoresis equipment prior to start-up of the output.
Never place any objects other than high voltage connectors rated to
1000 V into the output jacks.
Use electrophoresis equipment that can only be connected when the
protection lid is closed.
Never attempt to remove the outer casing or make any repair. Contact
our Service Department or your distributor if the need for servicing
should arise.
PS 304 XL Manual, 10_2015
7
If the power supply is used in a manner not specified by the
manufacturer then the protection systems of the equipment may be
impaired.
Never place an electrophoresis instrument on top of the Power Supply!
Site the unit such that the rear side has at least 20 cm of clearance to
provide for adequate unit ventilation.
For additional information, please call your distributor or our Service
Department.

6 Operation
Remind that last set output values are memorised.
6.1 Unit power up and immediate starting
1. Connect the AC line cord to a grounded, 3-prong wall outlet.
2. Connect the power supply to an electrophoresis device using the power cords
supplied.
3. To turn the power supply on, press the main power switch located on the rear
panel. The STOP LED (#11) illuminates, and the output LEDs will display zeros.
4. To display and check last set values, depress SET/OUT switch (#1)
As soon as this switch is activated, the output LED displays last output set values.
5. If Volts and mA set values are correct, press START/STOP switch (#9) for starting
the run. The green LED (#10) illuminates.
6. The actual values are immediately displayed. According settings and gel
resistance, one of the constant mode LED will be lit: #5 for constant voltage, #6
for constant current.
7. When separation is complete, press START/STOP (#9) to stop the run.
8. Turn off the power supply by using the main power switch on the rear panel.
6.2 Adjusting output set values when unit is in STOP mode
1. Depress the SET/OUT switch (#1).
As soon as this switch is activated, the output LEDs display last output set values.
2. The volts LED (#5) is blinking at first. Increase or decrease voltage by the help of
the two SET switches (#8).
3. Depress VOLTS/mA switch (#2) in order to select mA. The mA LED (#6) is blinking.
Increase or decrease current by the help of the two SET switches (#8).
4. Press SET/OUT switch (#1)to display the new actual values.
Maximum output values are as follow:
for 300 Volts - maximum current 400 mA (120 Watts)
for 400 mA - maximum voltage 300 Volts (120 Watts)
PS 304 XL Manual, 10_2015
10
6.3 Adjusting output set values when unit is in START mode
1. While the unit is running, depress the SET/OUT switch (#1)
As soon as one of this switch is activated, the output LEDs display last
output set values.
2. The Volts LED (#5) is blinking at first. Increase or decrease voltage by the help of
the two SET switches (#8).
3. Depress VOLTS/mA switch (#2) in order to select mA. The mA LED (#6) is
blinking. Increase or decrease current by the help of the two SET switches (#8).
4. Press SET/OUT switch (#1) for displaying the new actual values.
5. When separation is terminated, press START/STOP switch (#9) to stop the run.
6. Turn off the power supply by using the main power switch located on the rear
panel.

6.4 FURTHER INSTRUCTIONS
1. To view the set values during the run, depress the SET/OUT switch. The Led
display the set values as long as this switch is depressed. Once the SET/OUT
switch is released, the LED will display the output values for three seconds, and
then switch back to displaying the actual output values.
2. It is possible to change the values during the run without depressing the STOP
switch.
3. To change the output set values during the run or in STOP status :






Depress the SET/OUT switch (#1). As soon as this switch is activated, the
output LED display last output set values.
The Volts LED (#4) is blinking at first. Increase or decrease voltage by the
help of the two SET switches (#8).
Depress V/mA switch (#2) in order to select mA. The mA LED (#6) is blinking.
Increase or decrease current by the help of the two SET switches (#8).
After 3 seconds, the new actual output values are automatically displayed.
To read immediately the new actual values, press SET/OUT switch.
4. In START status, when the SET/OUT switch is depressed, the LEDs display the
output set values during three seconds and then switch back to displaying the
actual output values.
5. To establish the limiting (constant) mode for the particular experiment, set the
controlling parameter to the output desired, and increase the other output set
value until the appropriate mode LED (Constant voltage or Constant current )
illuminates.
6. If the non-controlling output set values is reached during the course of the run, the
power supply will automatically crossover to the new mode and control output
relative to that mode. The appropriate mode LED (Constant voltage or Constant
current ) will illuminate.
7. If automatic crossover is desired during the run, adjust the output set value of the
second controlling parameter to the maximum setting desired. When actual output
relative to the second controlling parameter equals its output set value, the output
will cross over from the first controlling parameter to the second.
8. When the run has been completed, depress the STOP switch to cease power
output. Wait one minute before disconnecting the power cords from the gel unit.
9. Turn the main power switch off when the unit is not in use.

power is operating again after a power failure or repetitive micro failures during a
cycle.
Simultaneously, the message “Str” is displayed and the STOP LED blinks for 10
seconds before operating again.
