Electrophoresis Power Supplies
Manual programming
The manual mode allows to set voltage, current, power and time for a routine electrophoresis run. Parameters can be changed temporarily without interrupting the run.
Method programming
Up to 9 different programs, each with 9 steps, of frequently used parameters can be stored in the non-volatile memory for future recall. Reads volt-age in 1 V steps, current in 1 mA steps and power in 1 W steps. Each step is able to recall a next one, providing a flexible multiple step function for special techniques. Parameters of the running \step can be changed temporarily without inter-rupting the run.
Voltage ramp
The method mode also allows to program a linear voltage gradient for any step provided the limiting current or power is not attained.
Timer
Timer or volt-hour controlled operation is a useful standard feature on all models. The micro-computer will automatically terminate the run and sound an alarm when the count down of the selected value is achieved.
Automatic cross-over
Each model has constant voltage, constant current, constant power capabilities with automatic cross-over and shows which parameter is kept constant.
Automatic recovery after power failure
After a mains power failure the instrument will automatically continue the run for the remaining time.
Data-logging
Stores up to 3600 output values (voltage, current and power, time or volthours) including program number and step.
Data Transfer
A free data acquisition software for PC can be downloaded from our website. It allows to visualize and examine the stored run details via RS232.
Remote control
All power supplies can be controlled by a computer using special commands.
Safety precautions
The user is protected from potential shock hazard since the AC line is automatically disconnected from the high voltage transformer when a ground leakage path is detected.
The instrument is fully protected against any overload condition including accidental short circuit of the output.The high voltage cannot suddenly appear at the outputs. It will always increase smoothly up to one of the pre-set limits is reached.Galvanic RS232 input/output insulation prevents ground loop interferences when connected to a computer.
Warranty
Three year warranty.
