Digital Energy Meter – Black & White (EV Charging)

A precision-built digital energy meter designed for real-time EV charging monitoring, delivering accurate electrical data, overload protection, and memory retention for safe and reliable single-phase EV charging. Key Capabilities 6-in-1 Real-Time Monitoring (±1% Accuracy) — Voltage, Current, Power, Units, Frequency & Power Factor Smart Overload Safety Alerts — Indicates unsafe EV load conditions Built-In Memory Retention — Stores kWh data even during power cuts Wide Operating Range (80–260V AC) — Stable performance in Indian power conditions EV-Compatible Design — Direct replacement for W2 Ultra & W3 Ultra Performance & Design Bright LCD display shows all critical electrical parameters required for safe and accurate EV charging Designed to continuously monitor voltage, current, power draw, energy consumption, frequency, and power factor in real time Smart overload indication alerts users when EV load exceeds safe operating limits, helping prevent overheating or wiring damage Resettable energy counter allows accurate tracking of individual charging sessions Built-in memory retains kWh readings and backlight state even during power outages Supports external CT sensor up to 100A for high-current EV applications EV-grade internal components engineered for long-term, continuous charging environments Simple single-phase wiring enables easy integration and direct replacement for existing Wundercurrent chargers Electrical Parameters Explained Voltage (V): Displays socket voltage in real time. Below ~180V EVs may charge slowly/refuse; above ~250V risk of heating or charger cut-off. Current (A): Shows how much current the EV is drawing. Helps verify charging speed, detects wiring/socket issues, and prevents overload. Power (W / kW): Displays real-time power consumption. Useful for checking charging speed and identifying fluctuating supply. Energy Consumption (kWh): Shows total electricity units consumed. Enables accurate cost calculation and billing verification (ideal for hotels, resorts, workplaces, shared charging). Frequency (Hz): Normal supply should be close to 50 Hz (India). Unstable frequency can cause EV charging interruptions and protects sensitive EV electronics. Power Factor (PF): Healthy EV charging typically requires PF between 0.95–1.0. Low PF indicates wasted electricity and inefficient charging.
