1. A safe voltage unit comprising:
a first terminal configured to be connected to a first power source;
a second terminal configured to be connected to a second power source; and
a pair of switches connected between the first terminal and the second terminal, wherein the pair of switches comprise a first switch connected in series with a second switch, and wherein the pair of switches are configured to control a flow of current through the safe voltage unit,
wherein the safe voltage unit is configured to operate in at least one of:
a first mode of operation where the first switch is turned OFF and the flow of current does not flow through the safe voltage unit; or
a second mode of operation where the first switch is turned ON and the flow of current does flow through the safe voltage unit, and
wherein, when the safe voltage unit is in the second mode of operation, the first switch is powered by a voltage between the first terminal and the second terminal.
