 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.
-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.

-A real power supply system includes a voltage converter, a charger and a rechargeable battery. The charger included in the construction set charges the battery. The power supply system connects to the on-board information network/power network with [[wiring|standard loops]].

-With "ground" service, before 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.

 **Important notes** \\
-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.
