Question #3:
Question: What are the power requirements for the PinScore display systems and how were they determined?
Answer:
It was known when we started the development of PinScore systems that low power was an important guiding principle. Different generations of game displays each had their own power requirements and those designers budgeted for the technology at that time. With the PinScore display systems every attempt has been made to operate within that budget.
For those non-technical individuals, Power is measured in Watts(W), and Power is calculated by the Voltage(V) * Current(I). All of the current PinScore systems require +5V, with the exception of the PS-12739. The current required is different for each system. The method for finding the maximum operating current for my products is simple. Each system has been placed in a temperature chamber subjecting the system to 70 degrees celsius for a period of 24 hours. The system was placed in a state with all segments being illuminated at maximum brightness. Using an HP 34401A benchtop multimeter and an HP 6002A power supply, the current was measured over time and an average current was computed. Here are the results per system:
- PS-8000-P(S) 335 ma
- PS-8363-P 362 ma
- PS-10749-P(S) 381 ma
- PS-10877 (all versions) 410 ma
- PS-12232 (all versions) 660 ma
- PS-12502 (single board) 404 ma
- PS-2518-58 (single display) 25 ma
