kW a Voltios Calculadora
Determine el nivel de voltaje requerido cuando conoce el consumo de energía y el flujo de corriente máximo. Crucial para la planificación de distribución y la configuración de transformadores.
Descubrimiento de Voltaje
Potencia + Corriente → Voltaje
Diferencia de potencial requerida para entregar la potencia objetivo.
La Fórmula de Conversión
El cálculo del voltaje depende del tipo de circuito: la fase y el factor de potencia cambian el cálculo significativamente.
Sistemas de CC
V = (kW × 1000) ÷ I Potencia simple dividida por la corriente. Se usa para bancos de baterías, paneles solares y circuitos CC.
CA Monofásica
V = (kW × 1000) ÷ (I × PF) Estándar residencial y comercial ligero. El factor de potencia tiene en cuenta las cargas reactivas como los motores.
CA Trifásica
V = (kW × 1000) ÷ (√3 × I × PF) Estándar industrial. El factor √3 (1.732) es obligatorio para todos los cálculos de voltaje línea a línea trifásico.
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
- Identify the Power: Read the kW rating from your device or system specification sheet.
- Find the Current: Locate the ampere rating on the equipment nameplate or measure it with a clamp meter.
- Determine Circuit Type: Is it DC, single-phase AC (residential), or three-phase AC (industrial)?
- 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.
- 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.
