Installation Instructions
The MRC PWR-3030 Power Supply is actually a pre-installed instrument.
As long as it is placed on a sturdy and level surface in a safe and dry place,
and is further connected with a well-prepared electrophoresis system, it is
ready for operation.
Operation Instructions
*Note: To operate under constant voltage or constant current modes, adjust
the other parameter to the maximum value. For example, to operate under
constant voltage, adjust current to max before running using constant voltage,
and vice versa.
The PWR-3030 Power Supply is designed to operate under two modes: Constant
Mode or Programming Mode, depending on your electrophoresis conditions.
Use the Constant Voltage / Current / Power Operation for applications that
require only one specific voltage limit, current limit, and power limit
continuously during the entire duration of electrophoresis.

This section gives an instruction for constant mode operation. Constant
Voltage / Current / Power Mode allow you to specify a voltage limit or a
current limit to be used continuously during the entire duration of
electrophoresis. Review the guidelines provided in this manual before
starting electrophoresis using PWR-3030 Power Supply. We recommend reading
the guidelines provided in this manual for best results before starting an
operation.
