Bio-Rad Trans-Blot® Cell - Manual (Page 5)

1.2 Safety Instructions
Power to the Trans-Blot cell is supplied by an external DC voltage power supply. This
power supply must be ground isolated in such a way that the DC voltage output floats with
respect to ground. All of Bio-Rad’s power supplies meet this important safety requirement.
Regardless of which power supply is used, the maximum specified operating parameters for
the cell are:
300 VDC Maximum voltage limit
200 Watts Maximum power limit
50 °C Maximum ambient temperature limit
Current to the cell, provided from the external power supply, enters the unit through the
lid assembly, providing a safety interlock to the user. Current to the the cell is broken when
the lid is removed. Do not attempt to circumvent this safety interlock, and always turn the
power supply off before removing the lid, or when working with the cell in any way.
