Engineering inputs

Start here: Connected maximum electrical load

* Required for this basic result. Optional fields add other results. Only enter known values.

What else may be needed?

Add at least one equipment row; every row needs quantity and maximum input power. Cooling separately needs verified rack heat, temperature rise and air properties. Rack placement needs quantity, U size and start U for every row.

Still to enter: Equipment schedule: at least 1 row.

Calculation results

Preliminary engineering. Review the basis before using a value.

Connected maximum electrical load

Additional Input Required

— W

Do not count both PoE input and exported downstream load twice. All row quantities and powers required.

Typical operating electrical load

Additional Input Required

— W

Not inferred from maximum power.

Rack heat dissipation

Additional Input Required

— W

Use measured/manufacturer heat or an accounted energy boundary; electrical input is not automatically rack heat.

Sensible heat load

Additional Input Required

— BTU/h

1 W ≈ 3.412 BTU/h.

Ideal ventilation requirement

Additional Input Required

— m³/h

Simplified coefficient 0.33 is an explicitly selected air-property approximation. Fan static pressure and system resistance not included.

Rack placement

Additional Input Required

—

Requires integer start U, U per device and quantity for every row.

Equipment U requirement

Additional Input Required

— U

Shelves and blanking panels must be included as equipment.

Unallocated U capacity

Additional Input Required

— U

Negative means capacity exceeded; front-elevation placement checks overlapping blocks separately.

Single-phase input current

Additional Input Required

— A

Aggregate true PF must be applicable to the load.
