Technical meaning
- A constant-voltage driver regulates output voltage while the connected compatible load determines current draw within the driver's rating.
- It must match the LED load type, output voltage and capacity requirements.
Calculation use
- LED strip load estimates multiply watts per metre by length, then add driver headroom before comparing a compatible driver rating.
- The load calculation can also show current by dividing watts by output voltage, but that does not settle installation details.
Not the same as
- A constant-voltage driver is not interchangeable with a constant-current driver.
- Driver capacity is not wiring design. Voltage drop, heat, enclosure, protection and installation method sit outside the calculator result.
Australian context
- Australian LED strip planning should note output voltage, strip load, driver headroom and licensed-work boundaries before installation decisions.
Examples
| Example | Value | Planning note |
|---|
| 24 V LED strip | constant-voltage load | The driver voltage must match the strip rating. |
|---|
| 48 W calculated load | add headroom | A 60 W compatible driver may be a practical capacity check before other requirements. |
|---|
| Long strip run | not solved by rating alone | Voltage drop and installation layout need separate review. |
