Vending, Kiosk & Self-Service Equipment worked example

Payment Module Test Load with payment module test bench connected load of 30 kW: a worked example

Push payment module test bench connected load up to 30 kW and the picture changes. This example computes every intermediate figure at that operating point. Use it when payment module test load in vending, kiosk and self-service equipment is being quoted and energy is a real chunk of the vending, kiosk and self-service equipment cost stack.

The inputs for this scenario

  • Payment module test bench connected load: 30 kW (raised for this scenario; the documented default is 12)
  • Payment module burn-in runtime: 8 hr (unchanged)
  • Blended plant electricity rate: 0.12 $ / kWh (unchanged)
  • Payment modules tested during runtime: 1,000 units (unchanged)

Working through the calculation

  • Applying the documented formula (Total payment module test load energy cost = payment module test load connected load × payment module test load runtime × blended electricity rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 240 kWh for payment module test load energy used, the number this scenario is built around.
  • At this operating point the engine returns 28.8 $ for total payment module test load energy cost.
  • At this operating point the engine returns 0.03 $ / piece for energy cost per kwh.
  • At this operating point the engine returns 3.6 $ / hr for hourly payment module test load energy cost.

How this compares with the baseline

  • Against the tool's baseline example, where payment module test bench connected load sits at 12 kW and the headline result is 96 kWh, this scenario comes in 150% above the baseline at 240 kWh.
  • It computes total energy (kW connected load × runtime hours), total electricity cost at your blended rate, and the resulting cost per payment module tested. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Payment module test load energy used: 240 kWh (headline result)
  • Total payment module test load energy cost: 28.8 $
  • Energy cost per kWh: 0.03 $ / piece
  • Hourly payment module test load energy cost: 3.6 $ / hr
