EDIT [ 0 ]
U = 100V 0v
I = 500mA 0mA
P = 300W 0w
2. The cursor will flash at “U=□□□V”. Set the value of constant voltage by pressing “▲”or “▼”
button.
3. The cursor will flash at “I = □□□mA” when press “ENT” button. Set the value of constant current
by pressing “▲”or “▼”button
4. The cursor will flash at “P = □□□W” when press “ENT” button. Set the value of constant power
by pressing “▲”or “▼”button. The range of power can be set from 1 to 300W. The cursor will
return and flash at “U = □□□V”when you press “ENT”button. Set the value of constant voltage
again by pressing “▲”or “▼”button.

5. Power supply in Setting State now. Press “RUN/STOP” button, it will enter into Operating State.
EDIT [ 0 ] RUN! 00:01
U = 100V ▶100v
I = 500mA 350mA
P = 300W 35w
6. Power supply in Operating State now. Press “RUN/STOP” button, it will stop output and return
to Setting State.
7. In Setting State, continue to press “EDIT” button, itwill enter into Editing State and display:
“SAVE [□]” → “LOAD [□]” → “T= □□:□□” → “QUIT” → “SAVE [□]”…
EDIT [ 0 ]
U = 100V 0v
I = 500mA 0mA
P = 300W 0w
8. At “SAVE □”, press “▲”or “▼”button to select number of memory program. The range of
number is from 1 to 9. Then press “ENT”button to save current method into this program.
9. At “LOAD [□]”, press “▲”or “▼”button to select number that needed. The range of number is
from 1 to 9. Then press “ENT”button to load the current method from program.
10. At “T= □□:□□”, press “▲”or “▼”button to set operating time.
11. The range of timer is from 1min to 99hs and 59mins. Then press “ENT” button to save it.
EDIT [ 0 ]
U = 100V 0v
I = 500mA 0mA
P = 300W 0w
12. At “QUIT”, press “ENT” button to quit Editing state, and return to Setting State.
ERROR ALARM
1. When the power supply run with Over-load, it will stop automatically and alarm with buzzer,
then display“ERROR 1!”.Turn off the switch immediately.
2. When the power supply run with No-load, It will stop automatically and alarm with buzzer, then
display“ERROR 2!”.Turn off the switch immediately.

WARNING
Electrophoresis power supplies use high output voltages that are electrically isolated from earth
ground through a protective impedance to minimize the risk of electrical shock to the user. The
following guidelines should be observed and followed when using a power supply.
Electrophoresis power supplies have passed test for operation at temperatures between 0° and
40°C, with relative humidity between 0 and 95% non-condensing. Operating the power supply
outside these conditions is not recommended by our company and will void the warranty.
1. To ensure adequate cooling of the power supply, be sure that there is at least 6 cm clearance
around the power supply. Do not block the fan vents at the rear of the unit.
2. Always connect the power supply to a 3-prong, grounded AC outlet, using the 3-prong AC power
cord provided with the power supply.
3. Do not operate the power supply in extreme humidity (>95%) or where condensation can short
the internal electrical circuits of the power supply.
4. When taking the power supply into a cold room, the unit can be operated immediately.
However, when removing the power supply from the cold room, let the unit equilibrate to room
temperature for a minimum of 2 hours before using it.
5. Never connect a high voltage output lead to earth ground. This defeats the floating electrical
isolation of the power supply and exposes the user to potentially lethal high voltages.
IMPORTANT
This instrument is intended for laboratory use only. This product conforms to the class A standards for
Electromagnetic Emissions, intended for laboratory equipment applications. It is possible that emissions
from this product may interfere with some sensitive appliances when placed nearby or on the same
circuit as those appliances. The user should be aware of this potential and take appropriate measures to
avoid interference.
ENVIRONMENTAL CONDITIONS
Ensure the instrument is installed and operated strictly under the following conditions:
1. Indoor use only
2. ≤95% RH
3. 75-106 kPa
4. Altitude must not exceed 2000 meters
5. 4-40°C operating temperature
6. Pollution degree: 2
7. Mains supply voltage fluctuations up to ±10% of the normal voltage

AVOIDING ELECTRICAL SHOCK
Follow the guidelines below to ensure safe operation of the unit.
The Basic Power Supply has been designed to utilize shielded wires thus minimizing any potential shock
hazard to the user. BT Lab Systems recommends against the use of unshielded wires.
To avoid electrical shock:
1. In the event of solution spilling on the instrument, it must be dried out for at least 2 hours and
restored to NORMAL CONDITION before each operation.
2. Never connect or disconnect wires loading from the power jacks when the red indicator light of
power switch is on.
3. WAIT at least 5 seconds after stopping a run before handling output leads or any connected
apparatus.
4. ALWAYS make sure that your hands, work area, and instruments are clean and dry before
making any connections or operating the power supply.
5. ONLY connect the power cord to a properly grounded AC outlet.
AVOIDING DAMAGE TO THE INSTRUMENT
1. Do not attempt to operate the device if damage is suspected.
2. Protect this unit from physical damage, corrosive agents and extreme temperatures (direct
sunlight, etc.).
3. For proper ventilation and safety concerns, keep at least 10 cm of space behind the instrument,
and at least 6 cm of space on each side.
4. Use high level of precaution against the damages on the unit.
5. Do not operate the unit out of environmental conditions addressed above.
6. Do not operate the power supplies in high humidity environments (> 95%), or where
condensation may occur.
7. To avoid condensation after operating the power supply in a cold room, wrap the unit in a
plastic bag and allow at least 2 hours for the unit to equilibrate to room temperature before
removing the bag and operating the unit.
8. Prior to applying any cleaning or decontamination methods other than manufacturer’s
recommendation, users should check with the manufacturer’s instruction to see if the proposed
method will damage the equipment.

EQUIPMENT OPERATION
Follow the guidelines below to ensure safe operation of the unit:
1. NEVER access dangerous chemicals or other materials to prevent possible hazard of explosion
and damage.
2. Do not operate the unit without lids or covers to prevent possible hazards.
3. A temporary conductivity caused by condensation might occur even though this series is rated
Pollution Degree 2 in accordance with IEC 664.
