Rumus Konversi

Perhitungan tegangan bergantung pada jenis sirkuit — fase dan faktor daya mengubah perhitungan secara signifikan.

Sistem DC
V = (kW × 1000) ÷ I

Daya sederhana dibagi arus. Digunakan untuk bank baterai, array surya, dan sirkuit DC.

AC 1-Fase
V = (kW × 1000) ÷ (I × PF)

Standar perumahan dan komersial ringan. Faktor daya memperhitungkan beban reaktif seperti motor.

AC 3-Fase
V = (kW × 1000) ÷ (√3 × I × PF)

Standar industri. Faktor √3 (1,732) wajib untuk semua perhitungan tegangan antar-saluran tiga fase.

How to Convert kW to Volts

Calculating voltage from power and current is a fundamental electrical task — useful when verifying system design, checking nameplate data, or troubleshooting circuits. Because voltage, current, and power are linked by Ohm's Law and power equations, you need to know both the power in kilowatts and the current in amps to solve for voltage.

Key Takeaway

Higher voltage at the same power means less current flows. This is why transmission lines run at hundreds of thousands of volts — thin wires can carry enormous power with minimal resistive loss when current is kept low.

Step-by-Step Conversion Guide

  1. Identify the Power: Read the kW rating from your device or system specification sheet.
  2. Find the Current: Locate the ampere rating on the equipment nameplate or measure it with a clamp meter.
  3. Determine Circuit Type: Is it DC, single-phase AC (residential), or three-phase AC (industrial)?
  4. Apply the Power Factor: For AC circuits, locate the power factor (PF) on the nameplate — typically 0.8–0.95 for motors and 1.0 for purely resistive loads.
  5. Calculate: Divide (kW × 1000) by the appropriate denominator based on your circuit type.

Common System Voltages

  • 12V / 24V / 48V: DC systems — automotive, solar, telecom, and battery storage.
  • 120V / 240V: North American residential single-phase AC (split-phase).
  • 208V / 480V: US commercial and industrial three-phase AC.
  • 230V / 400V: European and international single-phase and three-phase standards.
