Bio-Rad CHEF MAPPER Power Module

The Bio Rad CHEF MAPPER Power Module contains the electronics for pulsed field electrophoresis. This includes a 350 V power supply, the switching functions, and drivers for the 24 electrodes. The front panel contains a two line fluorescent display, buttons, switches, jacks, and a fuse as described in Section 4. The fused power supply operates with a maximum of 9 V/cm, or 350 V. The lowest gradient is 0.6 V/cm, or 20 V. The drivers provide clamped homogeneous electric fields in the chamber and maintain them regardless of the pulse angle selected. This feature, dynamic regulation, regulates the potentials so that the proper voltages are maintained regardless of gel size or fluctuations in buffer conductivity or temperature.
