Important Read this instruction manual. Failure to read,
understand and follow the instructions in this manual may
result in damage to the unit, injury to operating personnel,
and poor equipment performance. s
Caution All internal adjustments and maintenance must be performed by qualified service personnel. s
This equipment has been designed and tested to conform to CSA1010 safety standards, as applicable to
laboratory instrumentation. This applies only to the EC300 when used as specified in the documentation, in its
intended applications, with Thermo Fisher Scientific approved electrophoresis 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 EC300 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 apparatus 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 current
capabilities of the EC300 power supply.
The output of the EC300 power supply is intended for connection to electrically isolated electrophoresis
apparatus only. Use only with electrically isolated electrophoresis apparatus with minimum isolation of 600V. Do
not connect any terminal of the EC300 output to earth ground. This may impair the safety protection provided
by the equipment, or cause equipment damage.
The high voltage output of the EC300 power supply takes some amount of time to decay when unloaded or
lightly loaded. Wait a minimum of 60 seconds after stopping a run before touching the power supply leads.
This equipment has a protective ground leakage current of less than 0.5mA using test methods defined in
CSA1010 and CSA151.
This equipment is for indoor use only.
Material in this manual is for information purposes only. The contents and the product it describes are subject to
change without notice. Thermo Fisher Scientific makes no representations or warranties with respect to this
manual. In no event shall Thermo be held liable for any damages, direct or incidental, arising out of or related to

Section 1 Introduction
Thank you for selecting a Thermo Scientific EC300 Electrophoresis power
supply. This manual describes the operation of the EC300. 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
Technical Services department if you need any assistance.
The EC300 power supply is designed to provide constant voltage or
constant current output to apparatus used in electrophoresis applications.
One to four sets of electrophoresis cells can be connected in parallel and
run simultaneously. The EC300 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
EC300 protects your electrophoresis cells from damaging over power
conditions. The EC300 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.
• 10-300V, adjustable in 1 volt steps
• 4-400mA, adjustable in 1mA steps
• 75W maximum output
• Automatic control mode crossover
• 0-999 minute timed run
• Automatic restart if loss of AC power (if enabled)
• Bright 3-digit display

Section 2 Set-Up and Operation
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 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. Power the unit on
by connecting the AC power cord to the power entry on the rear panel
then plugging the 3 prong AC plug into a power source. Connect the
power supply to a 3-prong grounded AC outlet, using the AC cord
provided with the unit only.
