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 V (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.
