Single-phase electronic energy meters (track-mounted) (hereinafter referred to as "energy meters") are high-tech products manufactured using advanced ultra-low power consumption large-scale integrated circuit technology and SMT processes. The key components are selected from internationally renowned brands for long-life, enhancing product reliability and lifespan. Equipped with an LCD display and RS485 communication function. This meter boasts high measurement accuracy, excellent stability, strong overload capacity, and high reliability.
Product Features
Independent electrical energy metering, accuracy class 1.0
Malicious load identification, effectively identifies non-compliant high-power appliances and resistive loads (hair dryers, rice cookers, quick-heaters, etc.).
Remote pre-paid, automatic power cutoff for non-payment, power restored automatically upon recharge.
Built-in system clock for scheduled on/off power functionality.
One in, two out; each path can be individually measured and controlled.
Based on the environment (daytime, nighttime, or other application scenarios), different time periods can be set with distinct overload thresholds (time-limited flow control and overload control).
Automatic power recovery function, capable of automatically restoring power after overloading or using a faulty load to trip the power off. The recovery time and number of power interruptions can be set.
Real-time monitoring of voltage, current, power, power factor, and other parameters.
Independent CPU, independent metering unit, independent storage unit; parameters configured locally, capable of running independently.
The meter can monitor the internal working temperature and the high-voltage terminal temperature (optional). Abnormal temperatures can trigger alarms or trip the circuit breaker as configured.
Content can be viewed by scrolling through buttons, and manual emergency reclosing can be achieved by pressing buttons (optional according to customer requirements).
