1. A contactor module for installation in a power post, said contactor module comprising:
a first region associated with a first section of a printed circuit board and comprising communication and control circuitry mounted on said first section of the printed circuit board, wherein a power converter provides power to the contactor module,
at least one second region associated with a second section of the printed circuit board, the at least one second region being galvanically isolated from said first region and each of the at least one second region comprising:
a 2-pole contactor mounted on said second section of the printed circuit board,
an energy meter associated with said 2-pole contactor and mounted on said second section of the printed circuit board,
a digital isolator for transferring signals and/or power between the first regions and a respective one of the second regions, said digital isolator being mounted across an isolation barrier extending between said first section and said second section of the printed circuit board,
said printed circuit board being sandwiched between two layers made of a conducting material, and
an enclosure.
