Operation modes 

Introduction 

The PowerEase

®

 90W Power Supply is a microprocessor-controlled power supply 

designed to meet most electrophoresis needs in a single, easy to use unit. The power 
supply offers two modes: Constant Voltage and Constant Current. Use the Constant 
Voltage or Constant Current Mode for applications that require only one specific voltage 
limit or current limit during the entire duration of electrophoresis.

Instructions for operating the PowerEase

®

 90W Power Supply in the 

Constant Mode 

are 

provided in this section.  The 

Constant Voltage 

or

 Constant Current Mode 

allows you to 

specify a voltage limit or current limit to be used during the entire duration of 
electrophoresis.  Review the guidelines provided in this manual before starting 
electrophoresis using the PowerEase

®

 90W Power Supply. 

A basic 

Constant Voltage 

or 

Constant Current Mode 

operating procedure of the 

PowerEase

®

 90W Power Supply is provided below. We recommend reading the 

guidelines provided in this manual for best results before starting an operation. 

1.

 

Use the power switch on the rear side of the instrument to turn on the PowerEase

®

 

90W Power Supply.  

The display screen will illuminate. 

The screen displays the last set 

(voltage) in large bold type on the left side of the 

display and 

TIME

 and 

AMP

 in small type on the right side of the display. 

2.

 

Press the 

Constant

 key to select either 

Constant Voltage

 or 

Constant Current

 from 

the display screen. 

The screen displays the selected operating mode in large bold type on the left of the 
display.  

3.

 

Use the 

 

 arrow keys to set the selected operation [voltage (VOLT) or current 

(AMP)] to the appropriate values. 

4.

 

Use the 

Mode

 key to select 

TIME

 and use 

 

 arrow key to set the time 

(hours/minutes) to specify the duration of the electrophoresis.  

5.

 

Press 

Start/Pause 

key to start electrophoresis.  The Red LED illuminates when the 

electrophoresis is running. 

6.

 

Press the 

Start/Pause

 key again to temporarily interrupt power to ongoing 

electrophoresis without terminating the operation along with LED flashing. 

7.

 

Press 

Start/Pause 

key to restart electrophoresis. 

8.

 

Press 

Stop 

key to stop the electrophoresis. 

Note:

 If the parameters need to be changed during the run you must press 

Start/Pause

, enter the 

changes, and then press 

Start/Pause

 once again to restart your operation. 

Note

: After stopping and restarting an operation, the timer resets to the selected time

Introduction 

The PowerEase

®

 90W Power Supply is capable of operating at limiting Voltage, or 

limiting Current.   We recommend operating the PowerEase

®

 90W Power Supply at 

limiting voltage for most applications. See below for more details.
