Formula
Ptotal = Σ(n × Punit) · Itotal = Ptotal / 24 · Ptarget = Ptotal × (1 + reserve ratio)Substitution
Ptarget = 17.76 × (1 + 25%) = 22.2 WCalculation Steps
- Convert each load entered in A to W at 24 V, multiply by quantity and sum.
- Add 25% design reserve to total power and round up to an example rating.
Result Explanation
A default 25% reserve is used for preliminary sizing. Verify simultaneous solenoid pickup, capacitive-load startup and high-temperature derating separately.
| Load | Quantity | Per-Unit Input | Subtotal |
|---|---|---|---|
| PLC | 1 | 12 W | 12 W |
| Sensor | 4 | 0.06 A | 5.76 W |

Formulas and FAQ
P_total = Σ(n × P_unit) · P_target = P_total × (1 + reserve)What should be checked for solenoid or capacitive loads?
Check coincident pull-in or startup peaks, supply peak capacity and temperature derating.
