DC Power Meters
DC power and energy meters are used for precise monitoring of direct current circuits by measuring key parameters such as voltage, current, power, and energy. Suitable for solar systems, EV charging, battery storage, and telecommunications. DC meters collects real-time data for optimized energy management, energy usage cost allocation, and revenue-grade billing.
