PowerEase® 500 Power Supply (220/240 VAC 50/60 Hz) - FAQs

Linear mode is a feature of the PowerEase 500 Power Supply that has not been described in the manual. The linear mode can be activated from the 'Edit' screen (where you would change settings for time, voltage, power, current). While on the “Edit” screen, press the left and right arrows simultaneously. This will activate another screen with a three choice menu where the third choice is linear mode. Move the cursor down to 'Linear mode' and turn on Linear mode by using the up/down arrows. Note: The PowerEase 500 Power Supply has been discontinued as of December 31, 2013 and our newer alternatives are the PowerEase 300W Power Supply and PowerEase 90W Power Supply.

Using the PowerEase 500 Power Supply, the number of Tris-Glycine or NuPAGE gels that can be run simultaneously is shown below:

- Tris-Glycine gels: 10 gels i.e., 5 XCell SureLock Mini-Cells
- NuPAGE Bis-Tris gels: 2 gels i.e., 1 XCell SureLock Mini-Cell
- NuPAGE Tris-Acetate gels: 6 gels i.e., 3 XCell SureLock Mini-Cells

The PowerEase 500 Power Supply can be run under a variety of conditions including constant voltage, constant current, and constant power. The default setting is for constant voltage. We recommend running our precast gels at constant voltage for the following reasons:

- They are continuous gels
- For most electrophoresis methods, resistance increases throughout the run. When run at constant voltage, current and power decrease throughout the run, providing a natural safety margin
- The same voltage setting can be used regardless of the number, or thickness of gels being run
If you want to use the PowerEase 500 Power Supply to run a gel at constant power, this can be accomplished by setting a voltage limit (at or slightly above the maximum voltage expected to be reached during the run) and then setting the power to the desired level. If no voltage limit is set and a local fault condition occurs, such as a poor connection, very high local resistance may cause a high proportion of the total heat to be generated over a small distance, damaging the electrophoresis unit and/or gel(s).

The PowerEase 500 Power Supply can be operated under a variety of conditions including constant voltage, constant current and constant power. The default setting is for constant voltage. We recommend running our precast gels at constant voltage for the following reasons:

If you would like to use the PowerEase 500 Power Supply to run a gel at constant current, this can be accomplished by setting a voltage limit (at or slightly above the maximum voltage expected to be reached during the run) and then setting the current to the desired level. In this way, the device will try to reach the set voltage. However, when it reaches the threshold current, the current will plateau and the run will switch to constant current (the limiting factor). If no voltage limit is set and a local fault condition occurs, such as a poor connection, very high local resistance may cause the voltage to increase to the maximum of the power supply. This can lead to local overheating and damage to the electrophoresis unit and or gel(s) or create unsafe conditions.

Yes, however, keep in mind that the LCD screen will fade away in the cold room. The PowerEase would still be working and this will be indicated by the green and red light. The screen should come back on when returned to room temp.
