The IPT-PS module 218 has, for example, a Philips microcontroller type 87LPC762 that data bytes represent the type of l-Wire bus probe and the probe data.

A set of four AC-Line outputs 606 are then connected to the four IPT-IPM’s, e.g., 120-123 in FIGS. 1 and 220-223 in FIGS. 2A and 2B. The voltage drop across the primary Winding of isolation transformer 604 is relatively small and insigni?cant, even at full load.
