 The power supply system, or PSS, is the heart of the satellite. The power supply system of real satellites charges the batteries from [[sun_battery|solar batteries]],​ converts the voltage of the batteries into a stabilized board voltage to supply to various devices. In some cases, the PSS is able to turn the power of individual consumers on or off either on-command or automatically. ​ The power supply system, or PSS, is the heart of the satellite.

-In the construction set the power supply system includes a rechargeable battery. The presence of solar batteries (SB) and the logic of rechargeable batteries ​charge-discharge ​are "​virtually"​ considered. The "​virtuality"​ of solar batteries is related to the fact that charging batteries from real solar batteries ​is difficult in the room; the effective charge ​will require an excessively large surface ​of SB panels. Therefore, the PSS is arranged as follows.The first part of the PSS (real) provides energy to all consumers. It is charged from the 220V network and contains enough energy for a "​flight"​ of up to 4 hours. The second part of the PSS (virtual) simulates the operation of the satellite ​power supply system. It has a limited ​reserve ​of virtual energy. ​Virtual ​part is shown at the request of PSS telemetry. This energy is replenished when the imitator ​of the solar battery ​is placed on the [[sim_sun|Sun simulator]], and when the virtual energy is run out, the task executing ​by the "​spacecraft"​ is terminated ​abnormal ​- as it happens in real life.+In the construction setthe power supply system includes a rechargeable battery.

-With "​ground"​ servicebefore the flight, the on-board batteries, of course, need to be recharged. For this purpose, the charger is connected to the 220V network. In this case, LED indicator on the PSS lights up in green. In the case of battery ​is discharging ​to the load (to the satellite network), the LED lights up red. With simultaneous power-on and load connection, the LED lights up in yellow.+As part of the "​ground"​ service before the flight, the on-board batteries, of course, need to be recharged.

-When working with the satellite, it is not recommended to leave the power supply system ​connected to the charger for a long time (more than 4 hours) when there is no load (green LED color), this connection can shorten the battery life. Other combinations of connections are allowed.+When working with the satellite, it is not recommended to leave the PSS connected to the charger for a long time (more than 4 hours) when there is no load (green LED color).
