Page II.3: Power unit (battery central)

I have separated the battery central components from the old astroserver. The battery and main fuse central will be stationary, the astroserver I can bring with me home when I do test with new components. No more climbing up the hill with the heavy battery!

The battery central connect to a car battery with 45 Amp/h capacity. It's just act as a filter and a backup if the power grid goes down. It can not hold it working a whole night, but a couple of hours.

From the fuse central I take power to the light in the observatory and power to the motors that shall operate the roof in the future. There is also a battery charger that is always powered and connected to the battery when I run the telescope.

An overview of the power unit. Fuses on the left up, The black box right up is a 3x cigarette power outlet. Bottom is the battery charger. The red and black cable at bottom connect to the battery.
