Constant Power Operations
From the mode selection screen, select constant power operation by pressing the appropriate function
key located to the right of the display. To get to the selection screen from an operating screen, press
Exit, or cycle the control logic off and then back on by pressing the gray ON/OFF key and selecting
MANUAL. The EPS-3000P-II(V) will display the last saved setpoint for constant power mode. To switch
between volts/current/power and time/volt-hours/temperature, press function key F1. To change a
parameter, press the function key located to the right of the display, next to the parameter you wish to
change. The EPS-3000P-II(V) will allow a new value to be entered using the keypad numeric keys.
Press the function key labeled “Enter” to complete the new setting. Press Clear to erase previous
keystrokes. Press Exit to cancel entering a new value. The EPS-3000P-II(V) will not accept a power
setpoint outside of the allowed range. Press Clear to re-enter an appropriate value.
The limit parameters are normally set to the power supply maximum values. The EPS-3000P-II(V) will
not accept a limit parameter outside of the allowed range.
Constant Temperature Operations
NOTE: The EPS-3000P-II(V) controls for temperature by regulating the power output by the unit
until the set temperature control limit is reached. The unit will generate a constant power output to
the selected device until the temperature setpoint of the gel is reached. Once the set temperature
control limit is achieved, the EPS-3000P-II(V) will regulate the power output to maintain the gel at a
fixed temperature. It is important to optimize the power required for an application so that there is
sufficient power output from the EPS-3000P-II(V) power supply to enable the gel to reach the required
temperature. If the output power is not sufficient in allowing the gel to reach the desired temperature,
the unit will not be able to control /limit the temperature of the device.
From the mode selection screen, select constant temperature operation by pressing the appropriate
function key located to the right of the display. To get to the selection screen from an operating screen,
press Exit, or cycle the control logic off and then back on by pressing the gray ON/OFF key and
selecting MANUAL. The EPS-3000P-II(V) will display the last saved setpoint for constant temperature
mode. To switch between volts/current/power and time/volt-hours/temperature, press function key F1.
NOTE: Only the power and temperature values will be control parameters in the constant temperature
mode. If you desire, the default voltage and current limits may be changed. However, the unit
will not control for either voltage or current while in the constant temperature mode. To change a
parameter, press the function key located to the right of the display, next to the parameter you wish to
change. The EPS-3000P-II(V) will allow a new value to be entered using the keypad numeric keys.
Press the function key labeled “Enter” to complete the new setting. Press Clear to erase previous
keystrokes. Press Exit to cancel entering a new value. The EPS-3000P-II(V) will not accept a
temperature setpoint outside of the allowed range. Press Clear to re-enter an appropriate value.
The limit parameters are normally set to the power supply maximum values. The EPS-3000P-II(V) will
not accept a limit parameter outside of the allowed range.
In addition, the EPS-3000P-II(V) will never exceed the maximum power output specification of 400W.
To run in the Constant Temperature Mode, an FBTEMP temperature probe must be plugged into the
unit. Please ensure that the FBTEMP temperature probe is securely sealed to the surface of the
apparatus to be measured.
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.
Set up a constant mode setpoint and limits as described above. Enter a time duration of 0-99
hours, 59 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.
