C.B.S. Scientific Electro-Eluter Concentrator 6
1.3 Safety
Power to the Electro-Eluter/Concentrator unit is to be supplied by an external DC voltage power
supply that must be ground isolated so that the DC voltage output floats with respect to ground.
For any power supply used, the maximum specified operating parameters for the units are:
Maximum Limits
250 VDC voltage
25 watts power
50 mA current
60° C ambient temperature
Current to the unit, provided from the external power supply, must enter the unit through the lid
assembly, providing a safety interlock to the user. Current to the unit is broken when the lid is
removed. Do not attempt to use the unit without the safety lid. Always turn the power
supply off before removing the lid, or when working with the unit in any way. Follow
safety precautions specified by the power supply manufacturer.
