| Single-phase rail LCD Meter | | The single-phase electronic energy meter is the use of advanced microelectronic technology and SMT manufacturing process of products, the products are used in rated frequency 50Hz (also produce nominal frequency of 60Hz) single-phase AC active energy measurement. The LCD display used in the table. With the measurement of high precision, high sensitivity, reliable performance, load width, low power consumption, small size, light weight, simple operation, easy to install and so on.
The products meet the IEC 62053-21 standard for electronic energy meter of the relevant technical requirements.
1. Has a positive and negative sides to the measurement function, and the accumulated energy in the same direction, that is included in the reverse power forward.
2. Power display with 7-bit LCD (see Figure 2) shows, in which five integer bits, two decimal places; it can be six integer bits, one decimal place; unit kWh, recording cumulative total active power consumption .
3. When the power meter device communicate with the outside world by the communication indicator light, said the state energy meter in communication.
4. Has the passive-isolated pulse output energy, pulse-output square wave, pulse width of not less than 80ms ± 20%.
5. Parametric programming (RS485 or infrared programming, setting, meter reading) can be set to meter the table number (address), active energy start reading passwords.
6. With a reverse direction feature: When the current is reversed, reverse indicator light1. Rated Current: 5 (20) A, 5 (30) A, 10 (40) A, 15 (60) A
2. Rated voltage: 220V, 230V
3. Rated frequency: 50Hz/60Hz
4. Accuracy Class: Class 1, Class 2
