Formulas Used

DCI = P / V

No power factor needed for DC circuits.

AC 1φI = P / (V × PF)

Single-phase AC — multiply voltage by power factor.

AC 3φI = P / (√3 × V × PF)

Three-phase AC — divide by √3 ≈ 1.732.

Frequently Asked Questions

How do I convert watts to amps at 48V?

DC formula: Amps = Watts / 48. For AC, divide by (48 × Power Factor). Example: 1000W / 48V = 20.8333 A DC.

What is 1000 watts in amps at 48V?

20.8333 A for DC. For single-phase AC at PF 0.9: 23.1481 A.

What is 2000 watts in amps at 48V?

41.6667 A DC. Single-phase AC (PF 0.9): 46.2963 A.
