Power requirements of the meteor cameras

Video camera (ICC): 0.4 A x 12 V =  5 W (measured)
Cuno time inserter: 0.3 A x 12 V =  4 W (measured)
VCR Panasonic:                     14 W (from the book), 5 A fuse recommended
Video monitor:                     29 W (operational only short times)
Laptop (Dell):                 ca. 20 W (estimated)

We will have two system configurations.

Sys1. Light curves and spectroscopy:

2 x ICC:  10 W
2 x Cuno:  8 W
2 x VCR:  28 W
1 x Mon: (29 W)
---------------
Sum:      56 W (on short term: 85 W)

Option A: only one Cuno

2 x ICC:  10 W
1 x Cuno:  4 W
2 x VCR:  28 W
1 x Mon: (29 W)
---------------
Sum:      52 W (on short term: 81 W)

Sys2. Rates and backup:

1 x ICC:   5 W
1 x Cuno:  4 W
1 x VCR:  14 W
1 x Mon: (29 W)
1 x Dell: 20 W
---------------
Summe:    43 W

NOTES:
(a) There are two Sys1
(b) For each Cuno, a GPS receiver would be nice to have for the time synchronisiation (if that is possible - will be checked by dvk). It is assumed that the receiver operates on its own batteries.
(c) The laptop has batteries, which last for 3h. It can be equiped with two batteries simultaneously. We need to check whether it is possible to charge the batteries from the car battery, but most likely yes.
