Descripción del producto

Functions and Features: 1. Long-term active energy measurement without any calibration. 2. Adopt LSI(large-scale IC)and SMT(surface mounting technology)which means advanced technology and simple structure. 3. Characteristics of long Life and high reliability exist in every electronic component. 4. LCD display with wide temperature scope, 5 Integers & 1 Decimal, 5. Meter reading and programming can be achieved with HHU or PC via **5 port or infrared ray. 6. Sample the current on neutral line and phase line at the same time to prevent one-fire-one-ground electric larceny root and branch. 7. Build-in magnetism-reserved relays can control the switch via **5 port or infrared ray. 8. Power break indicator. 9. Meter reading via infrared communication port. *0. Energy test pulse output interface. *1. Automatically switch calendar, time and leap year once set up at the first time (optional). *2. Store historical consumption data (optional).
