Electrophoresis Power Supplies

EV Series


Electrophoresis power supplies EV series can be run either in manual mode or in automated mode by using up to 9 different programs. 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. 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 voltage 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 interrupting the run. The method mode also allows to program a linear voltage gradient for any step provided the limiting current or power is not attained. Timer or volt-hour controlled operation is a useful standard feature on all models. The built in microcomputer will automatically terminate the run and sound an alarm when the count down of the selected value is achieved. Each model has constant voltage, constant current, constant power capabilities with automatic cross-over and shows which parameter is kept constant. After a mains power failure the instrument will automatically continue the run for the remaining time. Up to 3600 output values (voltage, current and power, time or volthours) including program number and step can be stored. A free data acquisition software for PC can be downloaded from our website. This software allows to visualize and examine the stored run details via RS232. All power supplies can be controlled by a computer using special commands. 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 until one of the pre-set limits is reached.
