Hi Dave!
Use the "Current consumption (for 24V applications the following must be halved)" table (readings in AMPS).
Top row - What is your target temperature ?? (I'll pick ZERO)
Compressor speed ...
2000rpm - Current is 4.0A
2500rpm - Current is 5.2A
3000rpm - Current is 6.2A
My ARB 47L uses the same compressor ... I work on an average of 1.2A/Hr per 24Hrs (29AHr/Day). It can be less than this. ARB quote 0.87A/Hr average. It will do this, but I find 1-1.2A is closer to real world experiance. I've tested with an ampmeter ... seems to draw around 3.8-4.2A when running. On startup it can go over 5A. Then it's down to how good the cabinet insulation is for the number of cycles per hour.
Cheers
