Secure Module Test Load with secure module test load connected load of 30 kW: a worked example

What does the result look like when secure module test load connected load reaches 30 kW? The full calculation is worked below with real intermediate numbers. Use it when secure module test load in payment terminal and retail hardware is being quoted and energy is a real chunk of the payment terminal and retail hardware cost stack.

The inputs for this scenario

  • Secure module test load connected load: 30 kW (raised for this scenario; the documented default is 12)
  • Secure module test load runtime: 8 hr (unchanged)
  • Blended electricity rate: 0.12 $ / kWh (unchanged)
  • Units processed during runtime: 1,000 units (unchanged)

Working through the calculation

  • Applying the documented formula (Total secure module test load energy cost = secure module test load connected load × secure 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 secure module test load energy used, the number this scenario is built around.
  • At this operating point the engine returns 28.8 $ for total secure 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 secure module test load energy cost.

How this compares with the baseline

  • Against the tool's baseline example, where secure module test load connected load sits at 12 kW and the headline result is 96 kWh, this scenario comes in 150% above the baseline at 240 kWh.
  • A figure at this level is achievable when secure module test load connected load is genuinely sustained, not just peaked for a shift. It assumes the connected load runs steadily for the full runtime; duty-cycled racks or ramped test profiles will draw less than the flat estimate.

Results at a glance

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