The PSU is housed in the electronics enclosure and there are two connections with the main board: voltage supply connection and auxiliary output connection. The voltage supply connection is implemented via a 15 pin connector with 14 wires, this connector supply the +3.3V, +5 V and +24 V voltages and the ground lines to the electronics. The auxiliary output connector provides the
There is an input connector to the supply implemented with a hard switch to provide the input voltage which is in the range
