Digital Energy Meter - Multi-Color (EV Charging)

A colour-display digital energy meter engineered for precise, real-time monitoring of EV charging parameters, ensuring electrical safety, accurate energy tracking, and reliable performance in single-phase EV charging setups.

Key Capabilities

Performance & Design

• Bright colour LCD display presents all critical electrical parameters clearly and simultaneously
• Continuously monitors 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 enables accurate tracking of individual EV charging sessions
• Built-in memory retains kWh readings and display settings even during power outages
• Supports external CT sensor up to 100A for high-current EV charging applications
• EV-grade internal components designed for continuous, long-duration EV charging environments
• Simple single-phase wiring allows easy installation and direct replacement for existing Wundercurrent meters

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): Indicates how much current the EV is drawing. Helps verify charging speed, detects wiring/socket issues, and prevents overload conditions.
• Power (W / kW): Shows real-time power draw. Useful for checking charging speed and identifying fluctuating power supply.
• Energy Consumption (kWh): Displays total electricity units consumed during an EV charging session. Enables accurate cost calculation and billing verification (ideal for hotels, resorts, workplaces, shared charging).
• Frequency (Hz): Normal supply should remain close to 50 Hz in India. Unstable frequency can interrupt EV charging 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.
