Section 1
General Information
• The EC-I05 Power Supply is intended for use with any
electrophoretic device designed to operate below 250 Volts and 500
milliAmps DC.
• Two sets of outputs operate in parallel to provide between 20 and 250
volts, up to 500 milliamps, and up to 75 watts in the constant voltage
mode.
• A single LED display provides output voltage or current readings.
• Overcurrent protection is provided by audible and visual alarms and a
single 1 amp slo blow fuse on the main circuit.

Section 2 Set-Up
Unpack and Check
Unpack and carefully examine the power supply. Report any damage to
the distributor. Do not attempt to operate this device if physical damage
is present. Save all packing material if damage is found.
Electricity Supply
Before connecting this device to the electricity supply, check the infor-
mation given on the power supply rating label and confirm the follow-
ing:
- Your electricity supply is single phase A.C. (alternating current) of
the stated frequency with neutral nominally at earth potential.
- Your supply voltage is within the stated range.
- The current rating is within the capacity of your supply outlet.
Warning This equipment must be earthed. s
The wires in the electrical lead are colored in accordance with the
following code:
Green Earth (Ground) White Neutral (Common) Black Live (Phase)
Connect the wires to a non-reversible plug as follows:
Green wire to the terminal marked E (Earth), G (Ground), or colored
Green.
White wire to the terminal marked N (Neutral) or Common.
Black wire to the terminal marked L (Live) or Phase.
Important Electrical Safety Notes Consult a qualified electrician if any
doubt or if your electricity supply system has any of the following:
- No Earth
- A Color Code different from the above
- Reversible plugs
- Supply and Return Leads that are both above Earth potential

Locate
Place the power supply in proximity to the electrophoretic cell(s) with
which it is to be connected. Be sure to place the power supply in a safe,
dry location with all the controls accessible.
Connect to Cell and Mains
Connect power supply to electrophoretic cell, then to the AC receptacle.

EC-105 3-1Thermo Scientific
Section 3 Operation
Power On
After the power supply is properly connected to the electrophoretic
cell(s), select the 10 range and set Voltage Select to the fully counter-
clockwise (minimum) position. Set the display switch to Volts and tum
on power using the Power switch. When "On," the red LED is illumi-
nated.
Select Voltage
Adjust the Voltage Select control to the desired output voltage. The
Select Control will increase the output voltage approximately 10 volts for
every incremental adjustment. The Lo/Hi range switch is set to the Hi
position whenever operating voltages above 140 volts are required.
Note The overcurrent alarm will sound whenever maximum output
current (500mA) is exceeded. Should this occur, reduce the operating
voltage until the overcurrent alarm goes off.
The volts/milliamps display switch will display either volts to nearest volt
or milliamps to the nearest milliamp, depending on the switch setting.
This switch may be changed at any time without affecting the output.
Disconnection
When disconnecting the power supply from the electrophoretic cell, for
any reason, first turn off the power switch and confirm that the red LED
is no longer illuminated.

EC-105 4-1Thermo Scientific
Section 4 Precautions and Service
Use the same precautions as with any electrical device. Do not operate
without the cover in place or with any possible short circuit. Do not
operate in a damp, humid environment where condensing moisture may
short out internal electrical components. When moving to or from a cold
room, allow at least eight (8) hours for the unit to temperature-equilibrate.
This power supply is equipped with a slo blow 1 amp fuse in the mains
circuit. Should this fuse open, the check fuse LED on the front panel will
illuminate.
Caution Use only 1 amp (3/4 amp for 240VAC mains) slo blow fuses in
this equipment. s
Should this product become excessively warm, smoke, or display erratic
information during operation, discontinue use immediately and contact a
qualified service representative.
Use only mild, non-abrasive detergents. DO NOT use solvents or immerse
in water, as this may cause permanent damage.
