There are two dedicated, floating 25 V<sub>AC</sub> transformer windings per slot, as well as several AC and DC buses shared by all slots.<br /> | There are two dedicated, floating 25 V<sub>AC</sub> transformer windings per slot, as well as several AC and DC buses shared by all slots.<br /> | ||
For each slot, two uncommitted transistors (one NPN and one PNP) are mounted in the mainframe. These are available for the module's power regulation circuits. | For each slot, two uncommitted transistors (one NPN and one PNP) are mounted in the mainframe.

Whereas TM500 mainframes supply filtered, unregulated DC voltages, in TM5000 units a switch-mode power supply feeds the DC rails. | |||
Whereas TM500 mainframes supply filtered, unregulated DC voltages, in TM5000 units a switch-mode power supply feeds the DC rails and provides regulated voltages. These voltages are lower than the ones specified for TM500 mainframes, but the lowest specified supply voltages coincide, ensuring full backwards compatibility of TM500 plugins when operated in TM5000 mainframes. | |||
The signal pin connections depend on the individual modules.
