1. 18 6 4 Operating Status Display The Power Pack P25 T is in one of the following three operating modes voltage limitation current limitation and power limitation depending on the selected voltage and current settings and the ohmic resistance of the electrophoresis chamber The operating mode is indicated by the two LEDs located below the display The following rules apply LED indication Display indication CURRENT LED illuminated Current limitation VOLTAGE LED illuminated Voltage limitation CURRENT LED and Power limitation VOLTAGE LED illuminated In the voltage control mode the output voltage will remain equal to the selected value see also chapter 5 8 Working with Constant Voltage Should the output current exceed the selected default value the current limitation function of the Power Pack P25 T is activated The output voltage is now adjusted to the ohmic resistance of the electrophoresis chamber The output current remains limited to the selected default value see also chapter 5 9 Working with Constant Current Should the user s selected voltage and current defaults exceed the maximum allowable output power of 200W the device will reduce the maximum allowable output current according to figure 1 in chapter 5 10 Both LED indicators are illuminated when the current limitation is accessed to indicate that the outp
2. 5 9 Working with Constant Current Adjust the current controller s set value to the desired output current see chapter 5 5 Current Setting when working with constant current The voltage controller s set value will then have been selected so high that the device will switch to current limit mode see chapter 5 4 Voltage Setting When the current output has reached the desired set value the Power Pack P25 T will limit the current The voltage output will then adjust to the ohmic resistance of the electrophoresis chamber and the current output will remain constant The LED indicator CURRENT see chapter 6 4 Operating Status Display is illuminated throughout the current limitation mode Should the set value for the voltage controller be selected too low the output voltage will therefore not suffice to reach the desired current The output power of the Power Pack P25 T is limited to 200W The maximum allowable current output of the device is limited to 200V as shown in figure 1 of chapter 5 10 Application example A semi dry blot should be conducted with a constant current of 800 mA For safety reasons the output voltage should not exceed SOV The following set values will be applied Output voltage 50V Output current 800mA 14 5 10 Power Limitation The output power of the Power Pack P25 T is limited to 200W Should the user s selected voltage and current defaults exceed the maximum allowable output power
